Gate Valve

Hyper-connection & Hyper-intelligence Control System Leader

PARALLEL SLIDE GATE VALVE
  • The disks (parallel) are in two halves separated by spring and are urged into contact with the opposing seat in the closed position by a spring.
  • Advantage to this design is that thermal expansion in the valve does not forces the Gate tighter into the seats.
  • As this valve closes, the disk slides across the seats until it bottoms out. So, it does not tighter in the full closed position
  • This valve should equip with Equalizing Pipe Line valve certainly. An equalizing pipe line allows the relief of fluid which might otherwise become trapped in the body chamber space (Body cavity) of the valve body.
CHARACTERISTICS AND MERITS
  • Gate valves are used for on-off Service.
  • Gate Valve are straight-through flow valves which provide positive shutoff with
  • minimal pressure drop (Low flow resistance coefficient) and flow turbulence. Large size valves with short end to end to are acailable.
  • Overcome the thermal expansion problems due to the increased temperature with applying the flexible wedge disk or parallel slide disk for high temperature conditions
  • Gate valve installations should always be made with consideration for the potential of bonnet over-pressurization caused by fluids which may become entrapped in the bonnet of a closed valve. Where this possibility exists, it is the user's responsibility to insure that proper venting is installed.
  • Excellent performance of open/close operations and fluid control capabilities,
  • Gate valves may be installed without consideration for the direction of flow, they are not recommended for use in a partially open, throttling position which are caues for erosion, noise and excessive wear.
