Diaphragm Valves
Diaphragm valves provide reliable shut-off and throttling service for corrosive, abrasive, and sanitary applications. The flexible diaphragm isolates the operating mechanism from the process fluid, ensuring contamination-free operation and extended service life.

The Guardian of Contamination-Free Flow
A diaphragm valve uses a flexible diaphragm to isolate the operating mechanism from the process fluid. This design prevents contamination and provides excellent shut-off for corrosive, abrasive, and sanitary applications.
REW manufactures diaphragm valves in Cast Iron, Cast Steel, and Stainless Steel body materials, available up to 300mm (12") diameter. Available with rubber, PTFE, or Teflon diaphragms for various service conditions.
Three Core Configurations
Each engineered for specific service conditions — from general water service to corrosive chemical applications.
