DI WATER VALVE

DI WATER VALVE

DI WATER VALVE part of the bandit series pneumatic valves

NACOM'S  DI WATER VALVES. The perfect valve for wet bench manufacturers or any semiconductor facility where ultra-pure DI water is required.


Our DI WATER VALVE is part of the "Bandit" series pneumatic valves that incorporates the proven PTFE Internal Bellows design .


Available in sizes ranging from 1/2" FNPT  going up to 1.0" FNPT in 2way or 3 way configurations.


What makes the DI Water valve different from the original Bandit valve is the body material being fabricated from a choice of PVC, POLYPROPYLENE, and PVDF. The OBV  valve has a PTFE Body and is used in applications with more aggressive fluids.  The 2way version of the DI WATER VALVE has a straight flow path and the 3way has a 90 degree Flow path.  The DI water valves body, cap and piston are fabricated from PVC, POLYPROPYLENE and PVDF  while the Bellows and backing plate are virgin PTFE.
