Frequently Asked Questions

What does NKA-15 do?

Pneuforce NKA-15 is a pneumatic check valve. The internal check element permits flow in its rated direction and blocks reverse flow. Verify orientation, opening pressure and required flow capacity.

What port size does NKA-15 use?

The primary port designation on this model is 1/2 NPT. Some multiport valves use different exhaust-port dimensions; consult the full product data before selecting fittings.

Does the valve restrict flow in both directions?

No. A check valve allows flow in its permitted direction and resists flow in the reverse direction.

What is cracking pressure?

It is the differential pressure required to begin opening the valve. Consult this model’s specification when setting a low-pressure circuit.

What should be checked before installation?

Verify model number, pressure and temperature limits, air preparation, direction of flow and the port/thread arrangement against the system design.
