China hydraulic control valve type introduction: According to the structure, connection and material classification

China hydraulic control valve is a commonly used fluid control equipment, according to the structure, connection and material can be divided into many types. This article will introduce the types of hydraulic control valves in China from a professional point of view.

1. Sort by structure

(1) Piston type Chinese hydraulic control valve: composed of body, piston, seat, valve disc, etc. When water passes through the piston, the valve opens or closes due to the movement of the piston. Piston type Chinese hydraulic control valve has simple structure, but poor pressure resistance, suitable for low pressure occasions.

(2) Diaphragm type Chinese hydraulic control valve: composed of body, diaphragm, seat, valve disc, etc. When water passes through the diaphragm, the valve opens or closes due to the movement of the diaphragm. Diaphragm type Chinese hydraulic control valve has good pressure resistance and reliability, suitable for high pressure occasions.

(3) Rotary Chinese hydraulic control valve: composed of body, valve cover, valve disc, valve stem, spring and so on. When water flows through the valve, the valve opens or closes because the kinetic energy of the water flows into rotational energy. Rotary Chinese hydraulic control valve has good regulation performance and reliability, suitable for large flow, high temperature, high pressure occasions.

2. Type by connection type

(1) Flange connection type China hydraulic control valve: through the flange and pipe connection, easy to install and maintain.

(2) Threaded connection type Chinese hydraulic control valve: through the thread and pipe connection, easy to disassemble and clean.

(3) Welded joint type Chinese hydraulic control valve: through welding and pipeline connection, with good sealing performance and strength.

3. Sort by material

(1) Cast iron Chinese hydraulic control valve: has good casting performance and mechanical properties, suitable for general occasions.

(2) Stainless steel hydraulic control valve: has good corrosion resistance and high temperature resistance, suitable for corrosive media and high temperature occasions.

(3) Copper alloy China hydraulic control valve: has good thermal conductivity and wear resistance, suitable for high temperature and high pressure occasions.

In short, China’s hydraulic control valves can be divided into many types according to the structure, connection methods and materials. When selecting Chinese hydraulic control valves, the appropriate type should be selected according to the actual needs and use environment. I hope this article can help you better understand the types and characteristics of Chinese hydraulic control valves.
