This compact, in-line, poppet style check valve allows fluid flow (liquid or gas) to pass through a pipe line in only one direction. Unlike some other style check valves, this fully guided poppet – spring design reduces the potential danger of pressure surges as a result of check valve slam. As the direction of flow reverses, the positive pressure differential across the valve (inlet to outlet) decreases and will want to reverse. As the pressure differential decreases to the point of full flow reversal, the poppet will have rapidly approached the seat so that at full flow reversal the valve is already providing an ANSI Class VI seal.

Chrome Plated Poppet for Wear Resistance

**Price May Vary with Materials of Construction, Size, and Selected Options/Alternatives**

Pressure-Containing Parts: Made from solid bar stock materials — unlike castings which have wall thickness variations and porosity.Body and Trim: Standard material is type 316 stainless steel. 316 stainless steel spring comes standard. (Alternate materials may be available. Consult factory.)
No-Slam Poppet Style: The spring force causes the poppet to seat rapidly at flow reversal. This reduces the chance of a pressure surge in the process lines that could result from a conditions of flow reversal.
Compact In-Line Porting
Mechanical Travel Stop: Damage due to over compression of the spring is reduced by mechanically inhibiting excessive poppet movement.
Captive O-Ring Seat: Reduces the tendency for O-Ring blowout.

This check valve is available in four different fixed cracking pressures. The soft seated poppet seals against the valve seat shutting off the fluid flow in a no flow, or reverse flow situation. Once the inlet pressure exceeds the springs pre-set cracking pressure, the poppet will lift off the valve seat and allow fluid flow through the check valve. The cracking pressure for the fixed check valve cannot be changed without ordering a replacement spring and accompanying spring insert. Before removing the check valve for servicing, or adjustment to the cracking pressure, it is important to take all necessary precautions to protect any service technician from possible harm by removing any line pressure from the system.
