Jordan Valve's Sliding Gate Seat Technology for Regulators and Control Valves

Jordan Valve's Sliding Gate Seat is an excellent alternative to traditional control valve trim designs. The benefits are easy to see. They include: 
  1. Straight Thru Flow – The control element is perpendicular to the flow, resulting in less turbulence and superior trim life.
  2. Constant Contact in Seats – The disc and plate are in constant contact. Therefore, there is no valve ‘chatter’, less mechanical wear and greater stability at the low end of the stroke. The constant contact results in a self-lapping and self-cleaning action. Jordan Valve sliding gate seats wear in – they don’t wear out.
  3. Easy Maintenance – There is only one moving part in the Sliding Gate Seats. The seats are not pressed or screwed into place, so removal is easy. Cv values are interchangeable and control valve action is easily changeable.
  4. Short Stroke – In regulators, this results in faster response to input signals, less droop (greater accuracy), and longer diaphragm life. In control valves, the short stroke of the sliding gate seat results in less packing wear. Additionally, smaller actuators can be used resulting in lighter weight, smaller envelope dimensions and less air consumption.
  5. Seat Materials – Jorcote is the standard seat material. Jorcote is harder than stainless steel and provides excellent wear, erosion, & galling resistance. It has a lower coefficient of friction than Teflon; providing higher pressure drop capability and less offset. Jorcote seats perform in temperatures from sub-zero to 550°F (288°C). These seats have been lab tested to 1,000,000 full stroke cycles in 70 psi steam and maintained ANSI Class IV leakage while displaying negligible wear.
  6. Disc Plate Overlap – The disc and plate overlap by 1/32” (0,8mm) around each orifice. 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.
  7. Multiple Orifice Design – The multiple orifice design of the sliding gate seat dissipates the wear energy and downstream flow, resulting in longer trim life and quiet operation.
