Haskel 54080 SS Check Valve
Features & Benefits:
- Combines the best features of durability and positive sealing
- Constructed throughout of 316SS for the high corrosion resistance essential in the chemical, processing and power generating industries
- PTFE soft seal for positive bubble-tight sealing (with gas) from cryogenic to +375F temperatures; seals also available for radioactive environments or up to +500F steam
- Sizes 1/4″ through 1″ use a ball, and for reduced inertia the larger sizes (1-1/4″ through 2″) use a poppet
- Cracking pressure is 1 to 4 psi
- Semi-soft means the check ball or poppet initially seats on the PTFE, but after the PTFE deflects a slight amount the ball or poppet comes to rest against the metal seat so the PTFE does not have to absorb the full load of the high pressure
- Internal passages have flow capacity equal to or greater than pipe of the same size capable of the rated pressure
- Design allows the removal of the springs from the flow path: the larger spring is outside the flow and simply provides a pre-load for the disk while the smaller spring (inside the cage) actuates the ball or poppet but the flow, which is routed through the cage windows, misses the spring entirely.
- Able to withstand extremely high shock loads and have been tested at rapid high shock up to 2 million cycles without failure
