Swing Check Valve With Counter Weight- GMK- Protect pipelines

Swing Check Valve With Counter Weight

GMK swing check valve equipped with a counterweight is a product that is used when there is a potential for significant dampening on large-scale pipes. There is a possibility of breaking between the seat and the disc if there is an abrupt change in the direction of flow coming from the pipeline. It is the purpose of the counterweight or damper mechanism to prevent the breaking from occurring. Both horizontal and vertical installations are possible with the use of swing check valves that are equipped with a counterweight or damper.

DESCRIPTION

GMK swing check valve equipped with a counterweight is useful when the flow is unobstructed and linear across the valve, the consequent pressure loss is negligible. As the media moves through the line, the disc rotates into the open position and becomes accessible. The closed position of the disc is maintained by the presence of back pressure in the line. We propose that, while installing the valve in vertical flow lines, you spin the counterweight 90 degrees in the clockwise direction. This ensures that the damper or counterweight will be in the horizontal position when the valve is ready to be used.

Benefits

Check valve with metal seating and a hinged disc
In order to prevent backflow, the valve may be installed in either the horizontal or the vertical position.
It is possible to attach the counterweight to either the left or the right-hand side of the valve.
To each other’s faces
Ductile cast iron was used for both the body and the bonnet.
Steel, stainless, for the obturator
The shaft is made of stainless steel.
The seat of the body is bronze.
Coating both the inside and exterior with an authorized potable epoxy coating of fewer than 250 microns.
