CF series multi-spring cylinder piston actuator
Overview

The CF series multi-spring cylinder piston actuator is a new generation of single-acting actuator developed by our company. Compared with the single-spring cylinder piston actuator, the multi-spring cylinder piston actuator has a smaller volume and a wider thrust coverage. Drive all kinds of linear action valves. This series of actuators are widely used in regulating valves, globe valves, gate valves and other straight-stroke valves, especially suitable for traps with small diameters and large differential pressures.

Features

◎Independent intellectual property rights, stamping membrane cover type multi-spring cylinder piston actuator (patent number: ZL 2017 2 0348333.2);
◎Compared with the traditional diaphragm type multi-spring pneumatic actuator, the output thrust is increased by about 30%, and the piston structure has a longer life;
◎Two structural forms of positive/reverse effect;
◎Permanent lubrication system design, long-term use without lubrication;
◎The surface of the substrate is galvanized, anti-corrosive and beautiful;
◎Support multiple control methods;
◎Can realize fault open or fault close;
◎Modular design of the whole machine, the number of return springs can be adjusted according to user needs, thereby providing a more suitable output force;
◎Comply with IEC61508 system safety standard, SIL certification level SIL3.
