High Temperature Needle Valve
Introduction:
The high-temperature needle valve adopts an upper threaded valve stem structure, which avoids direct contact between the medium and the valve stem thread. There is a heat sink on the valve stem, which has the function of heat dissipation at high temperature. The hard chrome-tungsten alloy steel ball valve disc greatly improves the material hardness of the valve disc under high temperature conditions, and the valve disc rotates three-dimensionally when the medium is washed, which significantly improves the valve disc. Improve the erosion resistance of the valve disc under harsh working conditions, and solve the problem of internal leakage on the sealing surface.
Features:
High-temperature needle valves have good sealing performance, and are generally used for the sealing of gas or liquid (such as steam, oil) media with small flow and high pressure.
It is an advanced connection valve in power station, oil refining, chemical plant and instrument measuring pipeline.
