BFDG7M43HX piston type tube force valve

Pipe force valve is the fifth generation new product of water pump outlet after old-fashioned manual control valves, hydraulic butterfly valves, multifunctional hydraulic valves, and hydraulic automatic valves. Through the fluid design of the valve, a straight flow channel is formed, which has low energy consumption, stable operation, and good sealing effect. It combines the functions of an electric gate valve, an electric butterfly valve, and a check valve. By improving the fast closing time, it can better eliminate water hammer hazards and protect the safety of water pumps and pipeline systems. When the steering wheel is turned in sequence, the large and small valve stems simultaneously drive the upper and lower cutting plates, compression tube sleeves, and close them, and vice versa to open them. In this way, the gate reciprocates up and down between the guide columns to complete the valve opening and closing work.

Pipe force valves are mainly used for the outlet pipelines of centrifugal pumps, mixed flow pumps, and axial flow pumps in automated water supply and drainage pump stations. They are designed with two types of control devices: piston type and diaphragm type, which can be respectively applied to clean water, raw water media, and sewage, slurry water media; Real time feedback on the online operation of valves can be provided through auxiliary components, achieving automatic control and remote detection functions for distance conveying projects; In terms of product types, the company has developed five specifications including ordinary type, low pressure return type, and sewage type to meet the needs of different customers and working conditions. Due to its compact structure, small size, and light weight, it is particularly suitable for large-diameter pipeline systems. It can be widely used in power, environmental protection, metallurgy, petrochemicals, water supply, municipal, food and other industries for water supply and drainage systems, sewage pump rooms, chemical fluids and other transportation systems. It is currently the most innovative, advanced and reliable pump station control equipment in terms of structure, performance and operation at home and abroad

Installation type description
1. Pipe force valves can be installed vertically or horizontally. For the convenience of installation and maintenance, horizontal installation should be given priority when space permits, and the valve shaft should be ensured to be horizontal.
2. When the valve is closed, the smooth surface of the valve plate is in the inlet direction, and the side of the valve shaft with the control cylinder top rod is in the outlet direction. Reverse installation is strictly prohibited. The distance from adjacent valves, bends, etc. shall not be less than 1DN.
3. When installed horizontally, in order to improve the stress condition of the pipeline, when the valve diameter is greater than 900mm, brackets or foundations can be set up to improve the stress condition of the pipeline.
