[Product Name: Double Clamp Swing Check Valve]

[Product Model: H74H]

H74H clamp swing check valve is suitable for nominal pressure PN1.6Mpa~42.0Mpa, Class 150~2500LB; Nominal diameter DN15-1200mm, PNS1/2-48 '; Working temperature: -196~540 ℃ on various pipelines, used to prevent medium backflow. Valve body materials include carbon steel, stainless steel, etc., which can be used in water, steam, gas, oil, acid media, etc.

[Product Introduction]:
The H74H pair clamp rotary check valve is an ultra-thin check valve that adopts a short structural size and a single valve disc design. The valve disc is equipped with an O-ring seal, which has good sealing performance. Compared with traditional rotary check valves, this series of valves has the advantages of no external leakage, can be installed at any position, good sealing performance, small linear vibration, low pressure drop, and zero seat ring wear.

[Working principle]:
The H74H clamp swing check valve adopts an internal rocker arm swing structure. The valve disc rotates around the axis and pushes the valve disc through the medium flow. When the medium flows back, the valve disc closes the valve by its own weight and the action of the backflow medium.

[Product Features]:
1. The valve disc closes quickly and the water hammer pressure is low.
2. It has a short structure, small volume, and light weight.
3. The valve disc can fully open under a very small pressure difference.
4. Smooth flow channel with low fluid resistance; Quick action and good sealing performance.
