Rotary disc gate valves

Disc valves are designed for installation on pipelines as shut-off and regulating devices.
as shut-off and regulating devices, they serve for shutting off the flow and
regulate the parameters of the working medium by changing its pressure
and flow rate.
The gate design with triple eccentricity and "metal-to-metal" sealing allow to increase the temperature interval.

media up to 325°C and significantly reduce the torque during opening-closing of the valve.
The triple eccentricity and metal-to-metal seals allow to increase the temperature range of the operating media up to 325°C and significantly reduce the opening-closing torque and increase the tightness of seals.
Due to triple eccentricity at the moment of opening/closing of the gate
During opening/closing, the sealing ring of the disc is not in contact with the seat and is completely stress relieved.
