مشخصات:
Gate valve to DIN/EN with flanged ends (AKG-A) or butt weld ends (AKGS-A), pressure seal design, body of forged or welded construction, non-rotating stem, split wedge with flexibly mounted discs for precise alignment with the body seats. Seat/disc interface made of wear and corrosion resistant 17 % chrome steel or Stellite.
Additional features ensure safe sealing to atmosphere:
Pressure seal bonnet. Low risk of leakage, particularly at high pressures and temperatures.
Graphite gland packing with packing end rings.
Reliable, tight shut-off and service-friendly design
Wedge holder with flexibly mounted split wedge. Precise alignment of wedge discs with body; wedge discs are easy to replace.
Actuating moments are absorbed by the wedge holder guided in the body. No additional loads on the wedge discs and the seat/disc interface.
Standard DIN/ISO top flange at the yoke head simplifies actuator mounting.
Additional safety and blow-out protection by standard back seat.
Long service life and high functional reliability
Stop nut as standard. Limited wedge action prevents jamming in closed position and ensures reliable opening of the gate valve even in the event of temperature transients.
Of the gland packing due to non-rotating stem with burnished shank.
Threaded bush runs in ball bearings for smooth actuation.
Hard-faced seat/disc interface made of wear-resistant and corrosion-proof 17 % chrome steel or Stellite.
