Pressure-Regulating Valves for Chemicals

For Use With: Chemicals
Temperature Range:
Polypropylene Body: 35° to 180° F
PVC Body: 40° to 140° F

A plastic body and fluoroelastomer seal stand up to harsh chemicals. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

Polypropylene valves withstand higher temperatures than PVC valves.
