Pneumatic V-type wear-resistant valve

Pneumatic V-type wear-resistant valve

Product features and applications: This valve is a specialized valve designed for powdered and granular media pipelines in melamine process systems. During the valve closing process, the V-shaped port moves tightly against the valve seat to scrape away crystals and impurities from the sealing surface, ensuring the reliable sealing of the valve. 2. The surface of the V-shaped sphere is sprayed with tungsten carbide high hardness coating using supersonic flame spraying technology, and the sealing surface of the valve seat is welded with Stellite hard alloy, which is resistant to erosion and wear. 3. According to the needs, insulation sleeves can be added to the valve to insulate it with high-temperature gas, preventing material crystallization on the inner wall of the shell.

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status

3/4 Way ball valve has T type,L type and X type. T type can make three orthogonal pipes connect with each other and cut off the third channel, and play the role of shunt and confluence. L type way ball valve type can only connect two pipes with each other orthogonal, can not keep the third pipe interconnected at the same time, only play the role of distribution.
