Forged Gate Valve 800LBS

JOEPAI has developed and produced the high-quality Forged Gate Valve 800LBS. According to pressure requirements, the middle of the valve body can be selected from three structures: bolted connection, middle welding, and pressure self tightening; The middle flange adopts sealing gaskets made of carbon steel, stainless steel, flexible graphite, metal ring gasket and other materials; Adopting handwheel transmission, electric transmission, gear transmission, and sprocket transmission; The valve has an upper sealing structure to assist in sealing; The valve seat adopts structural characteristics such as forged valve seat, stainless steel valve seat, and welded alloy sealing surface. Forged steel gate valve is one of the commonly used shut-off valves, mainly used to connect or cut off the medium in pipelines; Gate valves are suitable for a wide range of pressure, temperature, and diameter, especially for medium and large diameter pipelines.

Product Features

The Forged Gate Valve 800LBS developed and produced by Joepai is easy to maintain, with a simple structure and convenient disassembly and replacement; The product structure of forged steel gate valve is simple, small in size, and light in weight; Forged steel gate valves have low fluid resistance, and their resistance coefficient is equal to that of pipes of the same length; Tight and reliable, currently electric forged steel gate valves have good sealing performance and have been widely used in vacuum systems.

Forged Gate Valve 800LBS has low flow resistance. The internal medium channel of the valve body is straight through, and the medium flows in a straight line with low flow resistance. It is more effortless to open and close. Compared to globe valves, the direction of gate movement is perpendicular to the direction of medium flow, whether it is open or closed. High height, long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lowering is carried out through the screw. Water hammer phenomenon is not easy to occur. The medium can flow in any direction on both sides, making it easy to install. The two sides of the gate valve channel are symmetrical.
