Product Description

FR Series Pneumatic Eccentric Control Valve

The FR series pneumatic eccentric rotary control valve (also known as the cam flexure valve) adopts Masoneilan technology combined with China's characteristics. It integrates the advantages of single-seat valves, ball valves, butterfly valves, etc., and has prominent features such as a simple structure, small size, light weight, large rated flow coefficient, wide adjustable range, wide operating temperature range, small leakage, and good stability.

Since the valve core and valve stem only perform rotational movement, the friction force they bear during operation is very small. When the valve core and valve seat are in contact and closed, the flexible arm of the valve core produces slight elastic deformation and elastic tension under the thrust of the actuator, making the contact between the valve core and the valve seat more tight and firm. Therefore, the leakage of the eccentric valve is very small. At the same time, the actuator thrust required to close the valve is smaller compared with ball valves and butterfly valves.

For these reasons, this series of products is widely used in industrial process automatic control systems such as chemical industry, metallurgy, and power plants.

Note: If the allowable pressure difference exceeds the value in the table, it is recommended to use a piston-type actuator. If the Cv value is greater than 500, it is recommended to use a piston-type actuator. The allowable pressure difference shall not exceed the nominal pressure of the valve.

Accessories
Since the flow characteristic of the FR series pneumatic eccentric rotary control valve is approximately linear, a valve positioner (including an air filter pressure reducer) must be equipped in occasions where control accuracy is required. In addition, auxiliary components such as electro-pneumatic converters, position retaining valves, safety valves, travel switches, and solenoid valves can also be equipped according to process requirements.

The handwheel of the FR series is integrated with the valve, and it can be supplied without special indication when the user places an order.
