To match your application needs, CoorsTek Stem-Guided Plate Valves are available in a variety of pressure ratings and material combinations.
Seats — The CoorsTek standard seat is a three-webb, investment-cast, 316 stainless steel unit that is also available in a five-webb, high-pressure design. Both styles are also available in Monel® stainless steel. The three webb style is rated at a maximum of 4200 psi (290 bar).
Plates — Our general-service plate, used in most applications, is made with Delrin® plastic. It can be used at up to 1800 psi (124 bar) on our three webb seat and 3500 psi (241 bar) on our five webb seat when used in 70°F (21°C) fluid. The Delrin® material strength will retain 25% of its original rating at 160°F (71°C).
Titanium plates are recommended for high temperatures and/or high pressures. Titanium plates can be used at up to 2500 psi (172 bar) on our three webb seat and 4200 psi ( 290 bar) on our five webb seat.
Springs — CoorsTek springs are made with shot peened Inconel® metal. This provides the dependable service required for virtually all plate-valve applications.
Fasteners — All CoorsTek plate valves use Monel® stainless steel fasteners — complete with a nylon thread lock plug which prevents fluid leakage around the threads and keeps the fastener in place.
