ZPL160F Series Pneumatic-Operated Lined Regulated Diaphragm Valve consists of a multi-spring pneumatic diaphragm actuator and a diaphragm valve.
Product Overview
The diaphragm valve body features a smooth flow passage with an elastic diaphragm as the throttling element, and the valve bonnet is designed without a stuffing box. Consequently, the valve offers greater flow capacity than conventionalcontrol valveswhile maintaining zero leakage, and can function as a shut-off valve within the allowable pressure differential range. The air-to-open and air-to-close operations are achieved through direct and reverse-acting actuators, respectively. This valve is particularly suitable for regulating high-viscosity fluids, suspensions containing particles, fibrous media, as well as toxic and corrosive media applications.
