CoorsTek Abrasion-Resistant Valve Components

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.
