Swing Check Valve

Since their invention, GMK swings check valves have consistently dominated the market share of all check valve products sold for use in water and wastewater pumping systems. They are not only easily accessible, but also inexpensive, and they have modest head loss qualities even when fully opened. They are automated in the sense that they do not need any external power or control signal but instead function solely based on the reversal in the direction of flow. However, this category encompasses a wide variety of valve types, and each of those kinds has its own set of benefits that a person using the valve should be aware of.

GMK Swing Check Valves derive their name from the fact that they typically have a body and a closure member or disc that “swings” or pivots around a hinge pin. This gives the valve its characteristic movement. Because this valve is likely to experience vibration and wear while in operation, it needs to be equipped with stabilization spheres at the ends of the pins to eliminate the possibility of pin vibration. In most cases, the robust seat is shaped to the body as well as the spoke that traverses the body.


  • Energy efficiency, low maintenance requirements, and long service life are just some of the benefits you’ll enjoy thanks to the GMK Swing Check Valve’s thoughtful design.
  • Both the Lever and Weight and Lever and Spring designs are field-adjustable and may be set up in either a horizontal or a vertical pipeline.
  • The strength and durability of ductile iron surpass those of regular grey iron.
  • It is possible to purchase GMK Swing Check Valves with either drop-tight robust seating or aluminum bronze metal seating.
