Cast steel gate valve connected by valve cover bolts

Overview and Application

Cast steel gate valve connected by valve cover boltsThe elastic wedge-shaped gate is guided by a cast guide rail; Can adapt to valve seat deformation caused by thermal effects and connecting pipeline loads; Can ensure the reliability of sealing under low pressure differential conditions; Can avoid adhesion or protrusion between the gate and valve seat under harsh working conditions; It can be applied to situations with strict requirements for valve closure tightness and reliability, such as high-pressure and high-temperature steam conditions.

Cast steel gate valve connected by valve cover bolts

feature

Valve stem: Lift and lower the valve stem, easy to operate while ensuring sealing

Cap bolt: using double headed bolts, easy to disassemble packing

Process hole: easy to disassemble sealing ring retaining ring

Graphite sealing ring: can maintain good sealing even under instantaneous high temperature conditions

Hard sealing surface: high heat resistance, corrosion resistance, and wear resistance

advantage

1. Valve pressure decreases

2. The valve body guide rail allows the surface of the valve seat guide groove to slide

3. The valve seat and gate surface are welded with Stellite hard alloy to ensure the operational performance of the valve under high pressure differential conditions
