Product Overview
Introducing the H71 Wafer Check Valve, a true marvel of compact engineering brilliance! This cutting-edge valve features a revolutionary wafer connection design that dramatically reduces the structural length to an impressive 1/4 to 1/8 of traditional flange check valves. This achievement marks a significant leap forward in both size and weight reduction, making it exceptionally lightweight at a mere 1/4 to 1/20 the weight of conventional alternatives. Revel in the advantage of rapid closure, significantly minimizing the risk of water hammer, all while benefiting from low fluid resistance. Seamlessly install it in both horizontal and vertical pipelines and experience how it gracefully overcomes the burdensome nature and maintenance challenges associated with traditional H41 flange check valves. Elevate your pipeline's efficiency and embrace the future with the modern marvel of the H71 Wafer Check Valve.
Structural Features
