ZTGZ/ZNAZ-64 pneumatic eccentric rotary control valve (hereinafter referred to as eccentric valve) is a commonly used angular stroke pneumatic control valve. After using an electrical converter, it can be combined with an electric unit combination instrument to form an automatic control circuit. It can be widely used in automatic regulation and remote control of industrial production such as chemical, petroleum, textile, metallurgy, and power stations.

Characteristics of ZTGZ/ZNAZ-64 Pneumatic Eccentric Rotary Control Valve:
The valve body has a smooth flow path, low resistance, light weight, and has greater flow capacity compared to single and double seat valves of the same diameter. Its weight is only about one-third of that of single seat valves of the same diameter. The valve core of the eccentric valve rotates, and the sealing performance of the packing box is good. At the same time, the actuator has a large output torque, and the leakage of the valve is small.
