Product: Pneumatic wafer ball valve

Introduction

Pneumatic wafer ball valve is composed of pneumatic double piston gear rack actuator and ultra-short wafer type ball valve. It can be widely used in petroleum, chemical, metallurgy, power station, In light industry and other fields.

Features

1. The actuator is connected by direct mounting with the advantages of compact structure, small size, light weight, small friction resistance, small backlash, stable and reliable action, etc;

2. The valve body adopts integral structure. Through precise processing and assembly, the ball is inserted from one end. The sealing retainer is tightened to keep the two valve seats and the ball core in good contact and bubble tightness;

3. Due to the integral structure of the valve body, the valve achieves an ultra-short face to face distance. Thus the weight of the whole machine is greatly reduced, which is only about 50% of the common ball valves of the same type.
