Safety Valve Actuator-Pneumatic Actuator Diaphragm Type

1,Product Description
The pneumatic diaphragm actuator is designed by one-stroke. the one stroke pneumatic piston actuator is mainly installed on the surface safety valve, used as the control mechanism of the main valve. The design is simple, reliable, easy to disassembly without the use of special tools and easy maintenance.

2, Composition and Structure

It is mainly composed of the cylinder, diaphragm, upper and lower cylinder cover, springs, seals and pressure relief devices and so on.

3, Working Principle
The working principle of diaphragm pneumatic actuator:
the pressure compresses the diaphragm and spring downward to drive the open or close of the gate.when the pressure disappears ,the spring automatically reset back to the normal position.

Pneumatic Actuator Piston Type

1,Product Description
the Pneumatic piston actuator is designed by one-stroke and two-stroke. Among them, the one stroke pneumatic diaphragm actuator and the one stroke pneumatic piston actuator is mainly installed on the surface safety valve, used as the control mechanism of the main valve. The design is simple, reliable, easy to disassembly without the use of special tools and easy maintenance.

2, Composition and Structure

It is mainly composed of the cylinder, piston, upper and lower cylinder cover, springs, seals and pressure relief devices and so on.

3, Working Principle
The working principle of one-stroke piston pneumatic actuator

The pressure compresses the piston and spring downward to drive the open or close of the gate.when the pressure disappears ,the spring automatically reset back to the normal position.

The working principle of two-stroke piston pneumatic actuator

The pressure compresses the piston and spring downward to drive the open or close of the gate.when you want to close or open the valve,the pressure goes into the lower piston through the selector valve and then drive the close or open of the gate.

Hydraulic Actuator

1.Product Description

Our hydraulic actuators are divided into two types:one stroke and two stroke.it is mainly used as the control system on the valve for controlling the on and off of the valve.

2.The Composition and Structure

It is mainly composed of the cylinder, piston (two-stroke) or spring(one-stroke), upper and lower cylinder cover, springs, seals and pressure relief devices and so on.

3.Working Principle

The working principle of two-stroke hydraulic actuator

The working principle of one-stroke hydraulic actuator

The pressure compresses the piston and spring downward to drive the open or close of the gate.when the pressure disappears ,the spring automatically reset back to the normal position.
