Advantages
– 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. -
