Highlight: Flange gate valve
Product introduction:
Gate valve refers to a valve in which the closing element (gate) moves vertically along the centerline of the passage. Gate valves are mainly used for cutting off in pipelines. Gate valve is a widely used type of valve. Gate valves can only be used for fully open and fully closed blocking in pipelines, and cannot be used for adjustment or throttling.Cast steel is mainly used for controlling the flow rate, pressure, and temperature of pipelines in various industrial automation production. For example: electricity, metallurgy, petrochemicals, environmental protection, energy management, fire protection systems, etc.

Product features:
1. Cast steel gate valve with low flow resistance.
2. Cast steel gate valve with less erosion of the sealing surface by the medium.
3. Cast steel gate valve with compact structure, opening and closing are more effortless.
4. The flow direction of the medium is not restricted, does not disturb flow, and does not reduce pressure.
5. As medium can flow toward either direction of the two sides, it is easy to be installed.
6. Short structure and manufacturing process and there are many materials available for high temperature and high pressure resistance.
