Material

▪ Long service life and high functional reliability

– Actuating moments are absorbed by the wedge holder guided in the body. No additional loads on the wedge halves and the seat/disc interface. – Easy mounting of actuator at yoke head. No modifications required. No need to dismantle pressure-retaining components.

8.

Fluid handled

– Stop nut as standard from PN 40. Limited wedge action prevents jamming in closed position and ensures reliable opening of the valve even in the event of temperature transients.

9.

Flow rate

– Of the gland packing due to non-rotating stem with burnished shank.

– Threaded bush runs in ball bearings for smooth actuation.

Always indicate the original serial number and the year of construction when ordering spare parts.

– Hard-faced seat/disc interface made of wear-resistant and corrosion-proof 17 % chrome steel. ▪ Threaded bush free from non-ferrous metals, for versatile application.
