The working principal of this valve is such that on the retraction of the piston, a “Negative Pressure” is created to “Pull Back” the material so as to achieve a quick cut off and or prevent dripping of material.

This valve is suitable for a wide range of material but is especially good for grease, silicone and pasty materials. Easy to maintain and operate, this valve is economical and robust.
