Product Details

ZSHO-16type pneumaticOCut off ball valve

Overview

ZSHO-16Type PneumaticOIt is composed of a solid ball valve and a pneumatic double acting actuator. It has the advantages of simple structure, small size, light weight, and easy operation, and can be widely used in automatic adjustment and remote control of industrial production processes such as petroleum, chemical, hydropower, and textile.

structural principle

OA ball valve is composed of valve body, ball body, valve shaft, sealing ring, packing, pressure plate and other components.

The actuator consists of gas, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bearing shell, adjusting bolt“O”Composed of main components such as rings.

Principle: The actuator and valve are connected by a connecting shaft. After the input of air pressure into the cylinder, a certain thrust is generated on the piston, causing the gear type output to rotate under the push of the piston, driving the valve shaft to rotate, thereby causing the ball valve body to rotate inside the valve, changing the flow area of the valve, and achieving the purpose of changing the medium flow rate through the valve.
