725D Piston Valves

The 725D Series piston valve delivers consistent, precise deposits of viscous fluids. Its unique diaphragm isolates wetted components from the actuator, providing superior wear resistance.  

Ideal for use with a variety of medium-to-thick fluids, the 725D pneumatic valve’s rugged construction features an ultra-high molecular weight (UHMW) polyethylene diaphragm that isolates the wetted components from the actuator and provides long wear.

A slight snuff-back at the end of the valve dispensing cycle prevents dripping between shots. All models feature the ability to be mounted in any position.

The 725DA-SS model provides stroke adjustment for both fluid flow and snuff-back control. The 725D-SS model is non-adjustable with fixed stroke travel.
