Keystone can supply all types of check valves, including swing, lift-style, disc/poppet style and wafer style.
Swing Check Valves are valves where flow is kept going in one direction using a swinging flapper that either swings freely or can be spring-assisted to maintain a minimal cracking pressure. The flapper and seat might both be metal, or include soft seats such as EPDM or Teflon among others. Larger flanged swing-type check valves may be assisted by a counter-weight. This is the most common style of check valve that we sell.
This is a check valve with a disc or plug similar to a globe valve that stays closed until sufficient flow acts on it to push it up and let the medium travel through the valve. These valves are often gravity-only, but can come in spring-assisted versions.
These are in-line check valves with a calibrated spring and poppet disk assembly that keeps flow going only in one direction. Poppet check valves come in a wide range of sizes, connection styles, materials, and calibrated cracking pressures.
This is essentially a swing style check valve, except it involves the swing disc mechanism only and is fitted between two flanges rather than inside a valve body.
