Purpose :

Cast wedge gate valves for high parameters of TU U 29.1-33704680-003: 2008 are used as a locking device on equipment and pipelines of thermal power plants (TPP, TPP, GRES), transporting water, steam. The valves are controlled by actuators: electric actuators of various manufacturers (A) , wheel (W), driving head with cylindrical (CG) or conical (CG) gear transmission.

Sealing surface – welding on corrosion-resistant steel

Tightness class – "С" as for GOST 9544.

Connection to the pipeline – by welding.

Medium supply – any direction.

Valve installation position on horizontal pipeline – electric drive up. For easy maintenance it is possible to install valves on a horizontal pipeline at any positon of upper semicircle; on a vertical pipeline – as required the installation position of the electric drive according to its operation manual.

Ambient class – U3 as for GOST 15150.

The valves are made with the locks of three design versions: the bayonet connection of the poppets with shackle (Figure 1), with spherical axial pivots of the "lentil" type (Figure 2) and "fungus" (Fig. In valves with a flap with spherical axial pivots of the "lentil" and "fungus" type, the covers are made with elements in the form of tapering surfaces that fix the poppets in the open position of the flap, which leads to a significant reduction in the vibration of the poppets.
