Integrated Lug Type Double-disc Swing Check Valve

Integrated Lug Type Double-disc Swing Check Valve uses stainless steel in the design that provides reliable service for many years to come. You can install this lug-type valve in clean water or air pipelines that are either horizontal or vertical. Both orientations are acceptable. Fluids such as sewage in its raw form and wastewater are two examples of the types of fluids that are not permitted to travel through this valve, Be careful. If it detects that the flow is going in the other way, it will instantly turn off. This valve is a great option for the management of gases that are toxic, corrosive, or harmful.

The GMK Integrated Lug Type Double-disc Swing Check Valve valve has a single cast body. Because of the architecture of this valve, the number of possible leak spots within the valve body is reduced. As a result, Double disc check valves made by GMK with integrated lug bodies may be used in a broad variety of liquid, natural gas, steam, and vacuum service applications.


  • GMK double-disc check valves have a shorter face-to-face dimension, weigh less, and have a lower breaking pressure as a result of their double-disc spring loading. 
  • Because of the way that the tension spring is built, it is able to elevate the disc, which prevents the “heel” portion of the elastomer seat from wearing down too quickly. 
  • Because each of the shafts is placed on its respective bearings, you are free to switch them out as necessary.
  •  At high flow rates, the stop shaft maintains the discs’ stable position.
  • Field maintenance can be performed without the use of any specialized equipment.
  •  ASME guidelines are adhered to in the development of GMK lug-type double disc check valves.
