Dependable Valve Service for Poor Fluid Quality
Abrasion-Resistant & Specialty Valves
Abrasion-resistant valves are recommended for applications where erosive particulates are causing premature failure of standard valves and suspended solids dictate the use of an open flow design. These valves are especially effective in saltwater disposal service, tank truck, and workover applications.
CoorsTek abrasion-resistant valves utilize a hardened 17-4 stainless steel seat and twin guided plate. The cage is made of 316 stainless steel and the springs are shot peened Inconel® metal. This abrasion resistant valve comes with a lock ring fitted between the cage and seat.
The twin-guided plate comes standard with a polyurethane insert — providing a more cut-resistant seal for the seat. The polyurethane insert is recommended when operating temperatures are 160°F (71°C) or less. Otherwise, we recommend a metal seal.
STEM-GUIDED PLATE VALVES
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.
