OVERALL：

GTs Pneumatic Diaphram Control Valve, which is composed of pnematic diaphragm Actuator and cage-guided valve, which is one of the principle products in G series Control Valves. The air-to-close type is made up of 857 or ZHGA direct actuator and the applicable valve type for example globe or Butterfly Valve. As the input signal pressure increases from the low limit to high limit，the valve travels from full open to full close. The air-to-open type is made up of 867 or ZHGB reverse actuator and the valve. As the input signal pressure increases from the low limit to high limit, the valve travels from full close to full open.

With characteristics such as cage guiding, balanced trims and easy replacement of trims, GTs Automatic Control Valve is mainly applied to common and tough services conditions, as well as zero leakage requirement conditions, high differential pressure services with clean liquid or gas as the fluid.

GTs automatic cage-guided control valve is sealed with bellows. With bellows, stem, spacer bush and other components connected into a whole, the leakage on the bonnet is eliminated. The product is fit for process control of chemical industry.

We can design and build it with Ball Valve, Check Valve, Globe Valve, Gate Valve and butterfly valves for 90% or above industrial applications. Please email your issues to our sales once you have any further construction projects.
