Product Summary

                     Main Features

Precision Vacuum Control Mainly for Tube Extrusion

Vacuum Pressure Ranges 1/100 psi to 5 psi

Hysteresis free control action

Precision setting with Vernier Knob

Remote or automatic setting option

Available in Manual or Servo Versions


The VPR series of regulators are designed to control vacuum pressure down to 1/100 psi, or a few mm of water gauge, on sensitive production processes such as small tube extrusion. The regulator balances the vacuum pressure against the tension of a low rate spring and allows enough air into the vacuum chamber to maintain the balance.  With the vacuum relief valve hung vertically on the balance spring and literally floating on a cushion of air, friction is negligible.  A vernier knob permits precision adjustment of the vacuum setting without any chance of causing a sudden disturbance.
