CONRADER NRP-A Unloader Valve 3/8in Inlet 14 Cfm Max

Conrader NRP-A unloader valve maintains pressure levels and prevents system overload by draining air from the compressors and providing a way for draining an air tank manually. It can convert a pressure switch control compressor into a constant speed unloader compressor.

Working Mechanism:

• When the air pressure inside the compressor's tank reaches the cut-out pressure of the switch, the switch trips off and interrupts the motor's power supply.
• This interruption opens the unloader valve and vents the accumulated air.
• When the tank pressure drops back down to the preset setting on the pressure switch, it trips again to release the unloader pin of the valve, restricting the release of compressed air.

Features:

• It features brass construction for structural rigidity and resists corrosion on exposed surfaces.
• This unloader valve is equipped with Viton / silicon O-rings for resisting temperature and chemicals.
• It has an FNPT vent outlet of 1/4 inch and can be pneumatically controlled for smooth operations.
• This unloader valve comes with a stainless steel ball & spring for heat resistance and a PTFE poppet to prevent overpressure.
