Precision Stainless Valve Pin

Function Description: The valve stem serves as the core moving component inside a valve. It transmits opening‑closing signals to regulate fluid flow direction and flow rate. Directly subject to medium pressure and friction, it is critical to the valve’s sealing performance and service life. Shangqin Advantages: “Mirror‑finish machining for zero‑leakage performance.” Supported by excellent rigidity of Japanese Tsugami machine tools, our valve stems deliver outstanding straightness and cylindricity on sealing surfaces. Precision turning creates high‑smoothness surfaces that greatly lower friction against sealing gaskets, maintaining superior sealing capability even under high‑frequency reciprocating motion. Technical Points: Surface hardening treatments such as nitriding and quenching are available; surface roughness of sealing area reaches Ra 0.2μm; corrosion‑resistant materials including 316L stainless steel and titanium alloy are supported; coaxiality is controlled within 0.01 mm.
