The valve is designed for installation in the schemes of CHPP units and for installation of pressure gauges. The valve in operation serves as a shut-off valve.
In operation the valve is controlled by means of manual drive - flywheel.The principle of operation of the valve is as follows: by means of the flywheel the rotation is transferred to the spindle; coupling of sealing surfaces of the spindle and the body with a given torque provides tightness of closing and reliability of the product; the design provides shut-off of the medium in any direction of flow; tightness in relation to the external medium is provided by the node "body-spindle".Diameter |mm|: from 10 to 10; Design pressure |MPa|: from 0,6 to 13,7; Temperature of medium
