I. Core Structural Features
- Rubber Flap Sealing Structure An integrated rubber flap is used (conforming to GB/T 12238 "Flanges and double-flanged butterfly valves"), which automatically opens using the medium pressure and quickly closes under reverse pressure (the red rubber flap component in the picture). The sealing surfaces are tightly fitted to achieve zero leakage, meeting the requirements of GB/T 13927 "Industrial valves Pressure test".
- Flange Connection Type Standard flanges are provided at both ends of the valve body (conforming to GB/T 9113 "Integral steel pipe flanges"), which are fastened to the pipe flanges with bolts for convenient installation and are suitable for medium and low-pressure pipeline systems.
- Self-Dropping Closing Design The rubber flap uses a gravity-assisted closing structure (weight design of the flap in the picture), which closes quickly and without impact noise. The water hammer suppression effect is superior to that of traditional swing check valves.
- Streamlined Flow Path The internal flow path of the valve body is designed to be smooth (straight-through structure in the picture), with a small flow resistance coefficient (≤1.5), low head loss, and significant energy-saving effect.

V. Typical Application Scenarios
- Building Water Supply and Drainage High-rise residential water supply system, preventing backflow of water in the pipeline when the pump stops, protecting the pump equipment.
- Sewage Treatment Outlet of the sewage treatment plant lifting pump station. The rubber flap is resistant to sewage corrosion and ensures unidirectional flow of the medium.
- Municipal Water Supply Urban water supply network branch lines. The low resistance characteristics reduce the energy consumption of the network and are suitable for high-flow transportation.
- Air Conditioning System Central air conditioning cooling water and chilled water circulation pipelines. The silent closing characteristics reduce system noise.
- Seawater Desalination Seawater transport pipelines. The EPDM rubber flap is resistant to seawater corrosion, extending the service life of the equipment.

Flange rubber flap check valve HC44X
The HC44X flange rubber flap check valve uses a flange connection and rubber flap sealing structure, conforming to national standards such as GB/T 12238.
The rubber flap design achieves zero-leakage sealing, and the self-closing design reduces water hammer impact. The streamlined flow path reduces energy consumption; the ductile iron valve body + stainless steel components are corrosion-resistant and impact-resistant, suitable for PN1.0~1.6MPa, 0~80℃ operating conditions.
It is widely used in water supply and drainage, sewage treatment, and other fields, providing reliable unidirectional flow protection for pipeline systems, and features energy saving and quiet operation.
