fully. Control (V40) valves are used to regulate flowing
fluid. Both types are used especially in power engineering, chemical industry
as well as other industries putting great demands on functionality at high
pressures and high temperatures. Working medium water steam gas other fluids
seawater Technical description The valve has a one-piece body which can be a
forged or a cast depending on nominal size and nominal pressure. The yoke-type
bonnet is also cast or forged and is connected with the body by means of a
bolted or flanged joint. The seat and the disc are hard faced. The disc is made
as either a plug type disc (valves V46) or a regulating disc (valves V40).
Valves with regulating disc have a linear regulating characteristic. Tightness
is achieved by means of special graphite gaskets and packing rings. Tightness
of the stem of valve type V46.6 is achieved by a bellow. The valves are
designed so as to be earthquake resistant. Operation manual (hand wheel, chain
wheel) electric actuator pneumatic actuator, hydraulic actuator actuator
located out of the valve Globe valves can be equipped with a locking device.
Position indicator on request. Operation is dimensioned for the working
parameters acc. to EN 13709.
