High Pressure Globe Valve

Description

The high-pressure globe valve is small in size, but the structure is not simple. The high-pressure globe valve is usually used in places where the temperature is high, so it can withstand high temperature. Relatively speaking, the high-pressure globe valve has many advantages, which are unmatched by other valves, and its working environment is special, which cannot be replaced by other valves.

Features:
1. The middle cavity of the valve adopts a pressure self-tightening sealing structure, and the sealing performance is better.n2. The sealing surface of the valve disc and valve seat is made of Stellite cobalt-based cemented carbide by spray welding, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance.n3. High temperature creep resistance design.n4. The valve stem adopts an integral forging structure, which is quenched and tempered and surface nitrided, and has good corrosion resistance and scratch resistance.n5. The depth of the bonnet stuffing box is reasonable, the packing is added with corrosion inhibitor, and the sealing is reliable.n6. The wear of the sealing surface of the globe valve.n7. The wear of the trapezoidal thread of the stem and stem nut.n8. Whether the packing is outdated and invalid, if it is damaged, it should be replaced in time.n9. After the globe valve is repaired and assembled, the sealing performance test should be carried out.
