Designed for industrial automation, our PPH Pneumatic Actuated True Union Diaphragm Valve combines polypropylene (PPH) corrosion resistance with reliable pneumatic actuation for precise media control. The true union design enables quick maintenance without pipeline disruption, while the diaphragm ensures bubble-tight sealing in aggressive environments. Ideal for chemical processing, semiconductor, and wastewater systems, it supports EPDM/FPM diaphragms for broad chemical compatibility. Available with normally open (NO) or closed (NC) configurations.
Single action, normal closed.
