Pneumatic butterfly valve is a valve and actuator, the actuator is rotated 90 degrees through the 4~20mA signal and the pressure of compressed air, and drives the rotary valve body, thereby to open and close the valve. The actuator can match most of the butterfly valve, the valve bodymaterial SUS316, SUS304 stainless steel, WCB, PVC, PP, UPVC... Etc.. Connection with flange, a clamp type. Is the ideal accessory products in petroleum engineering construction, chemical,electric power, mine, metallurgy, light industry, transportation, water supply, shipping, boiler project.

Valve positioner is South Korea YTC pneumatic valve positioner YT-1000R is an accepted 4~20mA DC current signal from the controller or control system, and to the angle travel pneumatic actuatingdevice mechanism to control valve position of air transportation.

Characteristic:

1 in the 5~200Hz range of non resonance phenomenon.

2 forward and reverse, between single and double acting easy conversion.

3 for small actuator can be to prevent shock by reducing locator orifice.

4 less air consumption, the economy is good.

5 replacement parts can realize split range control without 1/2.

The actuator is Italy AIR Torque pneumatic actuator "PT" series, material for aluminum alloy by oxidation treatment. "PT" series is AIR Torque company developed the latest generation of gearrack type pneumatic actuator, the comprehensive development of the latest technology and practical material improvement and become, have the following characteristics:

1 adhere to high quality, high quality and high reliability

Streamline structure compact 2

3 modern aesthetic design to increase the beauty of the art industry

4 high performance motion, high accuracy

5 design innovative

6 of all the design accord with the standard of the latest international

7 a high level of efficiency is not influenced by the environment performance more show its superior technology

8 surface protective coating to the new superior, showing excellent anticorrosion technology, the product has wide range of application

More than 9 specifications product selection of more affordable 10 general output shaft with patentand multifunctional indicator can choose, can choose to double action (DA), single action (SR), the supply of gas source can be provided in torque from 5.5 bar

6.7~9173 Nm. Pneumatic actuator optional accessories: function indicator, solenoid valve, limit switch box, a proximity sensor, positioner.
