  • Small forged steel linear regulating valve

Structural features:
Composed of a combination valve and a flow control scale, equipped with a micrometer scale and pointer, when the operator rotates the valve handwheel once, the scale pointer immediately shifts by 10% of the scale.
A scientifically designed regulating valve disc ensures controllable flow.
The sealing surface is welded with cobalt chromium tungsten hard alloy, which provides a more wear-resistant/corrosion-resistant and erosion resistant surface.
Manual operation for opening and closing, with linear flow regulation function.
If a locking device needs to be installed, it must be specified in the order contract.
Bolt connected valve cover (B.B) and rising stem bracket (OS&Y) or welded valve cover (W.B) and rising stem bracket (OS&Y)
The valve disc is divided into single or V-shaped double or four petals
