一.Product Introduction
WJ41H, WJ41W type PN16~PN40 bellows globe valve is suitable for various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with a working pressure of 1.6~4.0MPa and a working temperature of -29~350℃, but it is disconnected or connected to regulate the pipeline medium.
二.Product Features
1. The product structure is reasonable and the sealing is reliable
2.The sealing surface is surfaced with Co-based cemented carbide, which has good wear resistance, corrosion resistance, friction resistance and long service life.
3.The valve stem is tempered and the surface is nitrided, which has good anti-corrosion and anti-friction properties.
4.The material of the parts, the flange and the size of the surfacing end can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
5.The valve core can be made into cut-off type and adjustable type as needed
