ONE. Product Overview

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is used as the valve rod rotation circular disc to do, to be opened in order to realize the opening action of main block valves use pneumatic valve, can be designed to have a adjustment or section of the valve and the adjustment function, at present the use of butterfly valve on the low voltage and medium caliber pipeline more and more, pneumatic butterfly valve advantages mainly, simple structure, small volume light weight, low cost, The characteristic of pneumatic butterfly valve is particularly significant, installed in the upper air tunnel, pneumatic butterfly valve through two three (or two five) solenoid valve control easy operation, can also adjust the flow medium.

TWO. Product features

1. Small and light, easy to disassemble and maintain, and can be installed in any position.

2. Straight-line flow characteristics, good regulation performance.

3. Simple structure, compact, small operating torque, 90 degree turn and quick opening.

4. The connection of valve plate and stem adopts pin free structure to overcome internal leakage point.

5. The outer circle of the valve plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. Zero leakage is still maintained after opening and closing more than 50,000 times with pressure.

6. The sealing parts can be replaced, and the sealing is reliable to achieve two-way sealing.
