Poppet Valve

Poppet valves are precision machined for your application and are available in single deck, deck-and-a-half, and double deck valve configurations. CPI poppet valves are adaptable to existing plug style unloaders, or can be supplied with new plug unloader systems. Finger unloaders are also available for poppet valves with smaller nose diameters. The large seat and guard porting result in a valve that can be used effectively in applications in which debris or liquid is present. The poppet itself is designed to withstand high pressure differentials and high impact velocities, while providing a smooth, aerodynamic flow surface. Along with the large porting in the seat and guard, the poppets contribute to a low valve pressure drop, which results in lower valve loss power, lower valve temperature increase, and improved capacity. All CPI poppets are injected molded in-house to ensure complete quality control from raw material to finished product.

Reconditioning and Replacement Components

CPI poppet valves permit the easiest and most economical reconditioning when required. Seats can be fully reconditioned by the customer on-site utilizing our readily available reconditioning tools, or at one of our conveniently located service centers. Poppets and springs are easy to stock and are also readily available from CPI.

Poppet Valve Application Summary
Poppet Material	Recommended RPM Range	Maximum Operating Temperature	Poppet Advantages
Nylon	<1000 rpm	225 F	Low pressure drop due to high free lift area (Reduced valve HP loss) Standardization of poppet design requires less replacement parts inventory No maximum limit on valve outside diameter High lift can pass debris Can continue to run with damaged/missing poppets
PEEK	<1000 rpm	425 F
