– Additional features ensure safe sealing to atmosphere:

– Pressure seal design: The higher the pressure in the gate valve body, the tighter the bonnet joint. Metal-capped pure graphite gasket. Very low risk of leakage, particularly at high pressures and temperatures. Compact design.
– Graphite gland packing with packing end rings, protected against oxidation by metal caps.

– Robust body made of billet-forged steel.

– Very dense, homogenous and fine-grained microstructure. Extremely robust material able to withstand high stresses.
– Ideal for very high pressures and temperatures.
– Compared with cast bodies no risk of porosity and shrinkage cavities. Excellent weldability.

– 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.
