Overview and Application
The cast steel gate valve is bolted to the bonnet, and the elastic wedge-shaped gate plate is completely guided by a cast guide rail; it can adapt to the deformation of the valve seat caused by thermal effects and connecting pipe loads; it can ensure the reliability of sealing under low pressure difference conditions; it can Avoid bonding or rocking between the gate and the valve seat under harsh working conditions; it can be used in high-pressure, high-temperature steam conditions and other occasions that have strict requirements on valve closing tightness and reliability.
Features
Valve stem: lift the valve stem, easy to operate and ensure sealing
Gland bolts: Use double-headed bolts for easy removal of the packing
Process hole: easy to remove the sealing ring retaining ring
Graphite sealing ring: maintains good sealing even under instantaneous high temperature conditions
Hard sealing surface: high heat resistance, corrosion resistance and wear resistance
advantage
1. Valve pressure drops
2. The valve body guide rail allows the surface of the valve seat guide groove to slide
3. The surfaces of the valve seat and gate plate are made of Stellite hard alloy surfacing to ensure the operating performance of the valve under high pressure differential conditions.
