GRACO 571172 – Direct-Mount Vent Valves for G3 Pumps – BSPP, 24 VDC, 500-3500 PSI, Normally Closed, RH

G3 Max Pump Vent Valve Kit designed for normally closed operation with 24 VDC power supply. Features adjustable pressure relief from 35-241 bar (500-3500 PSI) and mounts directly to G3 pump with cable included. BSPP threading for international applications.

Industry leading feature for your lube system needs.

Vent valves are designed to be mounted to the G3 Electric Lubrication Pump to make it simple to install your injector based lube systems.

Easily mounts to your G3 pump.

Eliminates time and material costs associated with remote mounted vent valves.

24 VDC

Normally Closed

The normally closed valve works with the G3 Max pumps controller, and vents pressure based on the time duration you program into the G3 control.

Adjustable pressure relief is integrated into the valve, no need to purchase an additional relief valve.
