Product Description

I. Overview
Q671 pneumatic clamp positioning adjustment ball valve is one of the pneumatic ball valve, is the introduction of Italian technology for domestic design and development of a new generation of ultra-short flange distance ball valve, the shape of the ball core channel is rectangular, V-shaped and O-shaped. The product has the characteristics of compact structure, small size, light weight, easy installation, etc. It can be widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to automatically adjust or cut off the oil, water, gas and pulp or fiber fluid.
The

thin ball valve is a new type of ultra-short flange pitch ball valve developed by absorbing Italian technology and domestic design.
It adopts the direct connection method of the actuator connection, has the advantages of compact structure, small size, light weight, small friction resistance, small return difference, stable and reliable action.
