Weinhold - Steam Valve with Scavenging Function
Functioning, components and connection types of the Weinhold® steam valve with scavenging function are nearly identical with that of Weinhold® steam valve. In addition there is another function: scavenging and drying of the pressure reverse side. Apart from positions “shut” and “open” the lever can be shifted to a third position: “scavenging”. After shutting the third position can be shifted. The subsequent air scavenging of the pressure reverse side via an additional connection may start. After completion the lever is to be removed to position “shut”. A lever stop protects the valve against unintentional opening and scavenging.
The throttling effect is produced by turning the outside part. With that the bore is shifted towards the inside flow passage in off-centre direction, thus resulting in a cross section reduction. But the Weinhold® steam throttle is no shutting element; even in minimum flow cross-section position some creeping steam may escape.
The Weinhold® steam throttle is a solid and compact unity, which can be easily manipulated by hand. No additional tools are required. Its high leak-tightness prevents steam losses on the one hand and provides increased safety. By avoiding steam escapes, burns and scalds are prevented. To provide an even higher protection, the steam throttle is equipped with an additional thermal insulation cover on the outside.
The parts cannot be turned apart totally, thus preventing an unwelcome falling apart of the whole throttle. An outside scale allows to adjust the passage opening continuously.
