Plunger Packing:

Abrasion-resistant (A/R) valves - recommended for applications where abrasives are causing premature failure of standard valves and suspended solids dictate the use of an open flow design. A/R valves are especially effective in saltwater disposal service, tank truck, and work-over applications. A/R 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 A/R 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. However, the polyurethane insert is not recommended when operating temperatures are over 160
