Complete PTFE valve

Griffco PTFE diaphragm low-flow back pressure valves are designed to enhance the performance of chemical (dosing) pump systems by applying a continuous back pressure to the chemical feed pump, while also acting as an anti-syphon valve. The robust construction ensures reliability in heavy-duty industrial applications, among others.
The PTFE valve is characterized by the integrated flanges. The valve and the flanges are made out of 1 piece. This reduces the chance of leakage through seals or O-rings to zero. Very high chemical resistance, robust and leak free!
