Precision Valve Stem For Hydraulic And Pneumatic Systems

It is usually made of metal and has a certain length and diameter.

Its use method depends on the specific valve type and application scenario.

The valve stem is not only a moving part and a force-bearing part during the opening and closing of the valve, but also a sealing part. Therefore, when selecting the valve stem material, it must be ensured that it can withstand the impact and corrosion of the medium under the specified conditions and produce friction with the packing. Commonly used valve stem materials include copper alloys, etc., which need to have good machining performance and heat treatment performance.

In addition, the safety design of the valve stem is also very important, especially under working pressure, the valve stem should be prevented from being "blown out". To this end, an anti-blowout flange is set on the valve stem, and an annular ring is used to reduce the friction coefficient. In the hydraulic system, the excavator valve stem is used to control the switch of the hydraulic valve, thereby regulating and controlling the flow, pressure and flow direction in the hydraulic system.

The valve stem plays a vital role in valves and hydraulic systems. Its design and material selection must meet strict performance requirements to ensure its reliability and safety under various working conditions.
