Overview

The GB standard pneumatic ball valve adopts a straight through cast valve body, and the spherical surface is processed and hardened by special technology to make its surface smooth and wear-resistant. The GB standard pneumatic ball valve has the characteristics of long service life, compact structure, reliable action, high flow capacity, and low flow resistance coefficient;

Product Details

GBStandard pneumatic ball valveIt is a type of corner90Rotation class of degreescontrol valveIt is composed of a pneumatic piston actuator andOThe ball valve is composed of a type of valve core, and the valve core adopts a cylindrical through-hole sphere. There are two types of sealing materials: soft sealing and hard sealing.

GBStandard pneumatic ball valveUsing compressed air as the power source and receiving distributed control system（DCS）Programmable controller（PLC）Waiting for the switch signal, throughsolenoid valveCan be implemented forvalveQuick position control.

GBStandard pneumatic ball valveThe valve body adopts a straight through casting method, and the spherical surface is processed and hardened by special technology to make it smooth and wear-resistant. It has the characteristics of long service life, compact structure, reliable action, high flow capacity, low flow resistance coefficient, easy installation, good cutting function, and overcoming large pressure difference. The product is widely used in industries such as papermaking, petrochemicals, metallurgy, aerospace, food, medicine, water treatment, etc., and is particularly suitable for process control of high viscosity and fiber containing media.

Pneumatic piston actuators can be divided into two types: single acting and double acting. When the double acting pneumatic actuator loses air during use, the valve remains in the lost air position to ensure continued production. When the valve loses power or gas, it is in its original limit position (fully open or fully closed) to ensure that the production process is in a safe position.
