ZJHC ZJHC-16 ZJHC-40 ZJHC-64 Pneumatic on-off valve

Overview of ZJHC ZJHC-16 ZJHC-40 ZJHC-64 Pneumatic on-off valve

ZJHC ZJHC-16 ZJHC-40 ZJHC-64 Pneumatic on-off valve is designed with soft sealing structure and pneumatic diaphragm multi spring actuator on the basis of digesting and absorbing foreign advanced technology. Therefore, it has the characteristics of small size and lightness, and the leakage level can reach GB / t4213-92vi. It receives the signal from the regulating instrument, closes or opens the valve, and regulates the process parameters such as pressure, temperature, flow and liquid level in the system. It is suitable for the automatic control system requiring tight cut-off and compact installation space.

Features of ZJHC ZJHC-16 ZJHC-40 ZJHC-64 Pneumatic on-off valve

1. The sealing surface of valve core is composed of polytetrafluoroethylene and metal. Polytetrafluoroethylene plays a sealing role, and the metal part plays a limiting role, with reliable sealing performance.

2. The action mode of zjhc pneumatic diaphragm shut-off valve can be divided into air closed type and air open type. The air closing type is composed of Zha type positive action actuator and valve, and the air opening type is composed of ZHB reaction actuator and valve.
