The role of hydraulic or pneumatic system in mechanical engineering is mainly to increase the force by changing the pressure. The Body Casing and Fittings, valve body and other accessories are a major part. According to the pressure and the use of the environment and conditions, different mechanical manufacturing methods are used, such as casting, forging, etc. Medium and low pressure specifications of the valve body usually adopts the casting method (precision casting, gravity casting, low pressure casting) process production, and the valve core and valve seat sealing ring together to form a seal can effectively withstand the medium (water, gas, oil) pressure, the material of the valve body according to different process media, choose different metal materials, Commonly used materials are: aluminum alloy, cast iron, cast steel, stainless steel, carbon steel and so on!

Product Feature And Application
Hydraulic and pneumatic valve body application equipment or industry:
Metallurgy, construction machinery, all kinds of processing machine tools, agriculture, energy industry, transportation and shipping industry, special industry, general machinery, etc.
There are many kinds of valve body classification, according to the function of points, control mode points, spool structure form points, installation mode points.
According to the function, can be divided into three kinds of pressure control valve, flow control valve, direction control valve!
In construction machinery hydraulic and pneumatic system is an indispensable component, often used in the operation of construction machinery, control part. The main components are pressure gauge, oil pump, valve body, joint, tubing, cylinder and so on.
