Description
A Variable Flow Restrictor with Positive Shut-Off and Free Reverse Flow.
A wide range of flow adjustment in the controlled flow direction is possible because of the fine thread and tapered needle. A spring biased ball check or optional poppet check allows full flow in the opposite direction. Unwanted changes in adjustment are prevented by a lock nut.

- Maximum Operating Pressure (Non-Shock Service)
- Brass: 2,000 psi (138 bar)
- Carbon Steel: 5,000 psi (345 bar)
- Stainless Steel: 5,000 psi (345 bar)
- Maximum Operating Pressure (Flow Control Poppet)

- Cracking Pressure
- 1 to 2.5 psi (.07 to .17 bar) Soft seat check valves if left seated for a period of time, will have the rubber adhere to the metal it is in contact with. This results in an initial high crack point due to sticking. The degree depends on many things (time seated, pressure, etc.).
