790HP-LF High-Pressure Spool Dispensing Valve

790HP-LF High-Pressure Spool Dispensing Valves

The 790HP-LF high-pressure spool valve offers an effective solution for dispensing high viscosity materials such as silicones, sealants, and grease.

A spring snap-back retraction closes the valve resulting in a suck-back at the fluid outlet to prevent dripping.
