The Jordan Valve Sliding Gate Seat is a true value-added alternative to conventional trim designs. Here's why:
Easy Maintenance
Sliding Gate Seats only have one moving component. The seats are not pressed or screwed, making removal simple. Cv values are interchangeable. Valve action is easily changed.
Seat Materials
Jorcote is tougher than stainless steel, offering excellent wear, corrosion, and galling resistance. It has lower friction coefficient than Teflon, providing higher pressure drop capability and less offset. Jorcote seats handle temperatures from sub-zero to 550 ° F (288 ° C). Seats were tested to 1,000,000 full stroke cycles in 70 psi steam, maintaining ANSI Class IV leakage while exhibiting negligible wear.
Constant Seat Contact
Disc and plate are in constant contact. Therefore, there is no 'chatter' inside the valve, less mechanical wear and greater stability at the stroke's low end. Constant touch results in self-lapping and self-cleaning.
Straight Thru Flow
The control element is perpendicular to flow, resulting in lower turbulence and greater trim life.
Short Stroke
In regulators, this results in faster response to input signals, less droop (greater accuracy), and longer diaphragm life. In control valves, the gate seat's short stroke results in less packing wear. Smaller actuators may also be used, resulting in lighter weight, smaller envelope dimensions and less air consumption.
Multiple Orifice Layout
The sliding gate seat's multiple orifice dissipates wear from downstream flow, resulting in longer trim life and quiet activity.
Disc plate overlap
Disc and plate overlap 1/32 "(0,8 mm) around each tube. This creates an area of closure, not line of closure, resulting in better shutoff for a longer period of time, reducing waste and lowering costs.
