Types of Electrical Connectors Used for Hamilton Process Analytics Sensors
VP – This is a common connector used throughout the Hamilton sensor product line. VP is abbreviation for “VarioPin”. The VP designation often includes a number referring to the number of exposed poles on connector head. Example VP6 = 6 pole.
K8 connectors are typically used on pH / ORP sensors which lack temperature compensation. These connectors have a two pole design comprised of the center core and outer metallic threaded connection.
S7 & S8 – S7 and S8 connectors are typically found on sensors which no temperature compensation. They are the same basic design however S8 connectors have PG13.5 mounting threads, while S7 connectors do not. These connectors are recessed thus care must be taken to avoid moisture getting trapped which could lead to a short circuit.
M12 - Metallic threaded M12 connectors are found on Dissolved Oxygen Sensors and Cell Density products. M12 adapters have either 4 or 8 poles hidden within the socket. Since the poles are recessed avoid getting moisture inside the connection.
T82 – The T82 connector is sometimes known as a D4 connector. It uses a twist lock design to secure the cable to the sensor. These connectors are less common.
Memosens – These inductive electrical connectors are only found on digital pH sensors using Memosens technology. They use a twist lock design to affix the cable. There are no exposed metallic
connections on Memosens connectors.

A Visual Understanding of Steam Induced Water Hammer
When improperly drained of condensate in a high pressure steam main fills with condensate and completely surrounds the steam, an implosion takes place causing devastating water hammer.
Draining condensate and keeping it away from the steam by using proper steam trapping equipment will prevent this from happening.
The following video, courtesy of TLV, dramatically demonstrates the principle behind water hammer and its potentially devastating effects.

Understanding Cavitation in Valves
Download the Flowserve Cavitation document here.
According to Wikipedia, "Cavitation is the formation of vapor cavities in a liquid, small liquid-free zones ("bubbles" or "voids"), that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities in the liquid where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave."
Cavitation presents serious concerns to engineers and specifiers of control valves. Understanding ways to mitigate cavitation is important. Flowserve has put together this excellent document on understanding cavitation and offers solutions on reducing or eliminating its effects.

The Basics of Control Valve Actuators
Control Valve (Flowserve Valtek) |
Control valve actuators control fluid in a pipe by varying the orifice size through which the fluid flows. Control valves contain two major components: the valve body and the valve actuator. The valve body provides the fluid connections and a movable restrictor comprised of a valve stem and plug that is in contact with the fluid that varies the flow. The valve actuator is the component that physically moves the restrictor to vary the fluid flow.
The video below introduces the viewer to basic control valve operation concepts and the basic types of actuators.

What Are Cryogenic Ball Valves?
Cryogenic Ball Valve (Flowserve Worcester) |
Cryogenic ball valves are high-performance shutoff valves for intermittent and continuous flow applications with temperatures to -425°F. They are used on tough applications involving all types of cryogens, such as oxygen, hydrogen, methane, ammonia, nitrogen, fluorine, LNG and deuterium.
Cryogenic ball valves include unique features to ensure safety and performance in cryogenic applications. Central to the cryogenic design is a rugged, one-piece, pressure safe stem with a Polyfill thrust bearing and stainless steel split ring. It provides design safety and low operational torque. Polyfill seats give you tight shutoff throughout the temperature range. With an orientation-controlled stem/ball connection and an upstream hole in the ball, you get positive overpressure protection.
Summary of specialized design features:
Brass Cryogenic Ball Valve (Flowserve Worcester) |
- Positive Ball Cavity Relief – An upstream relief hole in the ball prevents dangerous overpressure due to thermal expansion. On extended stem valves through 2", a one-piece stem with alignment pin assures proper orientation of the ball.
- Pressure Safe Stem – Both one-piece and two-piece, assembled inside-the-body stems are safe from blowout and are supported with Polyfill® thrust washers.
- Zero Leak Packing – Belleville live-loaded TFE packing rings and stem centering followers assure zero leakage through the toughest, high-cycle applications.
- Effective Bonnet Extensions – The stem extensions of cryogenic valves conform to standard industrial practices. That means wall thickness and lengths that keep heat transfer down, the packing frost-free, operational torques low, and actuators solidly supported.
- High-Performance/Low-Thermal Stress – The special “part compatibility” design of valve parts, Polyfill seats and body seals assure tight shutoff, zero body leakage and low torque through large thermal excursions from ambient to -425°F.
Cryogenic valves are normally available in four body configuration, in either stainless steel or brass:
- Three-piece construction - makes it easy to install, versatile in application and simple to maintain.
- The cryogenic diverter valve - accepts media through the bottom inlet port and directs it to one of two side ports.
- The wafer design - a flangeless cryogenic valve that mounts between ANSI Class 150 or 300 flanges.
- A flanged design - has a body cast with ANSI Class 150 flanges.
Application for cryogenic ball valves:
- Over-the-Road LNG-LPG Trailers
- Terminal Unloading Stations
- High-Purity Cryogenic/Gas Systems
- LNG Storage and Distribution
- CO2 and Nitrogen Injection for Enhanced Oil Recovery
- Over-the-Road CO2, LNG, Food Carriers
- Petroleum Refining Unleaded Gasoline (Gas Treatment Skids)
- Lyophilization Systems
- Air Separation Plants
- Liquid and Gaseous Oxygen
- Inerting and Heat Treatment

What Are Valve Positioners?
Digital Positioner (Valtek) |
A valve positioner responds to a signal from some type of master control system, typically a distributed control system (DCS), a programmable logic controller (PLC), or PID controller. The control system reads a signal from a process sensor (flowmeter, temperature sensor, pressure sensor, etc...) and compares that reading to the desired setpoint. A corrective signal, based on the difference, is provided to the valve positioner which re-adjusts (if necessary) the valve position to bring the system in to equilibrium.
Valve positioners are available with pneumatic, electrical, electro-pneumatic, and digital operation. Here is a brief description of each:
Pneumatic
Pneumatic Positioner (Valtek) |
Electric
Electric valve positioners receive an electric signal, usually 4-20 mA, 1-5 VDC, 2-10 VCD or 0-10 VDC and generally drive the motors in electric actuators. They perform the same function as pneumatic positioners do, but use electricity instead of air pressure as an input signal.
Electro-Pneumatic
Electro-pneumatic Positioner (PMV) |
Valve positioners are used throughout the process industries including power, pharmaceutical, chemicals, oil and gas, food and beverage, pulp and paper, refining and petrochemicals, pipelines, and many other processes.

A Process Industry Stalwart - The Plug Valve
Lubricated plug valve. (Flowserve Durco) |
Fluid process control operations commonly employ pumps, piping, tanks and valves as the means of transporting, containing and controlling the fluid movement through a system.
Valves, of which there are many types, provide control over the flow rate, direction and routing of fluids in a processing operation. Flow can be started, stopped or modulated between zero and full rate using a properly sized and configured valve. Some valves enable media flow to be diverted to a selection of outlets, in lieu of a single inlet and outlet pair. Specialized valves regulate inlet or outlet pressure, or prevent fluid flow from going in an undesirable direction. All of these capabilities are packaged into differing valve product offerings that present a very large selection array to a process designer or engineer.
Non-lubricated plug valve. (Flowserve Durco) |
Plug valves, like ball and butterfly valves, span from fully open to fully closed positions with a shaft rotation of 90 degrees. The “plug” in a plug valve is installed in the flow path within the valve body and rotated by means of a stem or shaft extending to the exterior of the body. Plugs are tapered toward the bottom and are fitted to a seating surface in the valve body cavity that prevents fluid from bypassing the plug. An opening through the plug, the port, can be shaped to provide particular flow characteristics. There are two main types of basic plug, lubricated and non-lubricated. Lubricated plug valves have a cavity into which a sealant is injected. The sealant provides a renewable seal between the plug and the body, prevents internal leakage, and protects the seating surfaces against corrosion. Non-lubricated plug valves utilize an elastomeric body liner or a sleeve in the body cavity that is pressed in to the body of the valve by the plug's wedge-like shape, with the result of reducing the friction between the plug and the body.
Plug valve considerations:
- 90 degree rotation from open to closed provides fast operation.
- With proper configuration, can be well suited for frequent operation.
- Availability of corrosion resistant liner may provide comparative cost savings because valve body can be constructed of less expensive material.
- Design is simple and employs a low parts count.
- Valve can be serviced in place.
- Generally, low resistance to flow when fully open.
- Reliable leak-tight service due to tapered plug wedging action, replaceable sleeve, and injection of lubricant in some variants.
- Potential issues of concern for plug valve application include a short list of items.
- Higher friction in the plug closure mechanism may require comparatively higher operating torque than other valve types.
- Without a specially designed plug, generally not well suited for throttling applications.
- Rapid shutoff delivered by plug design may not be suitable for some applications where hammering may occur.
