Quick Exhaust Valve 1/4 NPT

This brass nickel-plated quick exhaust valve manages compressed air lines with a 1/4 inch NPT female inlet and outlet. It operates between 29 and 145 psi and handles temperatures from 14 to 158 degrees Fahrenheit. The unit meets PED Directive 97/23/EC, REACH Regulation 1907/2006 and RoHS Directive 2002/95/EC standards.

Build Quality And Mounting

The brass body with nickel plating resists corrosion in pneumatic systems. Female NPT threads on both ports allow direct connection to standard 1/4 inch fittings without extra adapters. The compact 3/8 inch overall length fits tight manifolds and control panels where space is limited.

Upgrade From Basic Silencers

This valve replaces simple exhaust silencers when faster cylinder return strokes or reduced back pressure are required. The jump is worth it for machines that cycle rapidly and lose dwell time through restricted exhaust flow. Buyers who need integrated flow control or solenoid piloting will need a different component.

Questions about this item

What pressure range does the 1/4 in NPT quick exhaust valve handle?

The valve operates between 29 psi minimum and 145 psi maximum, so it exhausts air within that window on any 1/4 in NPT line.

What thread and clearance does the 7982 valve need to mount?

Both ports are 1/4 in NPT female; the body is 3/8 in overall length, so allow at least that depth plus wrench clearance on the hex.

How do I install the valve without blocking exhaust flow?

Thread the inlet port to the pressure source and the outlet port to atmosphere or a silencer; reversing them traps pressure and prevents quick exhaust.
