Product Description

Advanced Inline Force Control Valve,
diaphragm type / piston type

This model is the fifth generation product developed from old manual operated valve, hydraulic butterfly valve, multifunctional valve and hydraulic control valve. It is installed at the outlet side of the pump station. After structure reform, this model has straight line flow channel with advantages of energy saving, smooth running, perfect sealing performance. It mixes the functions of electrically operated gate valve, electrically operated butterfly valve and check valve. Its closing speed is very quick so as to avoid pressure surge and protect the pump station and the pipeline.
This valve is popularly used in the downstream pipeline of centrifugal pump, mixed flow pump and axial flow pump of automatic water supply and drainage system. There are two operation choices: Piston type and Diaphragm type. It can be applied to many mediums such as clean water, source water, sewage and slurry water etc. 

It is very suitable for big size pipeline system because of its compact structure, small size, light weight. It is popularly used in pipeline of electricity power industry, environment protection industry, metallurgy industry, petrochemical industry, waterworks, city construction and food industry etc.

It is a new control device for pump station with the latest design, most advanced capacity, most dependable performance in the world market.
