Valve Components

There are many types of valves, such as hydraulic valves, globe valves, overflow valves, cleaning valves, gate valves, butterfly valves, ball valves, etc.

We are good at processing heat-treated valve core and valve sleeve, end cap and piston rod and other parts

The hydraulic valve is an automatic component operated with pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with an electromagnetic pressure distribution valve. Commonly used in oil circuits such as clamping, control and lubrication. There are direct acting type and pilot type.

The spool is a valve part that realizes the basic functions of directional control, pressure control or flow control by means of its movement.

Shut-off valves, also known as gate valves, are forced-sealed valves, so when the valve is closed, pressure must be applied to the clapper to force the sealing surface to not leak. When the medium enters the valve from below the clapper, the resistance to be overcome by the operating force is the friction force between the stem and the packing and the thrust generated by the pressure of the medium. The diameter should be large, otherwise the failure to bend the valve stem will occur. According to the connection method, it is divided into three types: flange connection, screw connection and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the shut-off valve is changed into the valve cavity from above the valve flap. At this time, under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, the diameter of the valve stem can be corresponding To reduce. At the same time, under the action of the medium, this form of valve is also relatively tight. China's valve "three chemical" once stipulated that the flow direction of the globe valve should be top-down. When the cut-off valve is opened, the opening height of the valve flap is 25% to 30% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the shut-off valve should be determined by the stroke of the disc.
