CH2M series double membrane head actuator
Overview

The CH2M series double membrane head actuator is a double-force pneumatic actuator with two membrane heads. Compared with a single membrane head actuator, it has a larger output thrust and can meet the demand for greater thrust. It can be used for the control of regulating valves, globe valves, gate valves and other straight-stroke valves that require large thrust.

Features

◎ Independent intellectual property rights, Bili type pneumatic actuator (patent number: ZL 2015 2 1095706.7);
◎Two structural forms of positive/reverse effect;
◎The output thrust of the double membrane head structure under the same pressure is increased by 50% compared with the traditional single membrane head structure;
◎Support multiple control methods;
◎Comply with IEC61508 system safety standard, SIL certification level SIL3.
