Overview

The ZJ(M)HL series pneumatic diaphragm control valve is a single-seat control valve . In addition to the various advantages of a single-seat plunger control valve, the unique symmetrical multi-hole cage valve disc is more effective for control Noise and cavitation are not only suitable for more demanding working conditions, but also various flow coefficients can be tailored to meet the more detailed process requirements of customers. You can choose multi-spring pneumatic membrane mechanism or electric actuator.
