Commonly used valves: electric actuators and pneumatic actuators

The  electric actuator  and pneumatic actuator in the commonly used valves, first of all, the pneumatic actuator in the Pneumatic Butterfly Valve in the dyeing and finishing plant, such as the KEYSTONE actuator, is to determine the torque of the butterfly valve first. With a simple and compact rack tooth design, using the entire piston area to output torque, the integral piston rack and pinion drive can reduce the number of seals, so that air leakage is minimized, in order to ensure that the valve can be accurately connected, the KEYSTONE actuator can be directly connected to the valve as a result of the output and installation standards, so as to save unnecessary processing. The gear shaft entering the bottom of the actuator makes the actuator easy to disassemble and assemble, and the anti-blowout device at the upper end of the shaft can make the actuator absolutely safe.

Pneumatic actuators in ball valves, such as aluminum alloy actuators for Pneumatic Ball Valves. First of all, it is necessary to have a compact two-piston tie-rod mechanism with quarter-turn output. The cylinder body is made of aluminum alloy material, the standard connection flange provides convenience for replacement and installation, the top of the quad, flat output shaft is easier to operate manually, the pneumatic actuator usually uses air, no corrosive gas and oil, the ambient temperature is -20 °C to +80 °C, and lubricant needs to be added under normal working conditions, whether it is indoor or outdoor installation. The output and installation standards can be connected directly to the valve, which saves unnecessary processing. The gear shaft entering the bottom of the actuator makes the actuator  easy to disassemble and assemble, and the anti-blowout device at the upper end of the shaft can make the actuator absolutely safe.
