Ductile Iron Rubber Disc Swing Check Valve For Water Pipeline

Ductile Iron Rubber Disc Swing Check Valve For Water Pipeline Use

Product introduction:

H44X (SFCV) series rubber disc check valve mainly consists of three main parts: body, bonnet and rubber disc.
The rubber disc in the valve is made of steel plate, steel rod and reinforced nylon cloth as the substrate, and the outer layer is covered with rubber. The valve disc has a switching life of up to 1 million times. The H44X (SFCV) series rubber disc check valve adopts a full flow area design, which has the characteristics of small head loss, less accumulation of debris, and easy maintenance.

The H44X (SFCV) series rubber disc check valve is mainly suitable for horizontal installation in water supply and drainage systems. It can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump. The H44X (SFCV) series rubber disc check valve can also be installed on the bypass pipe of the inlet and outlet pipes of the reservoir to prevent water from flowing back into the water supply system.

Check valves are generally suitable for clean medium and are not suitable for the mediums containing solid particles and high viscosity. The check valve is installed at the outlet of the water pump for shut-off and check purposes. It is an ideal equipment to eliminate the damage of water hammer to the water pump unit and pipeline network. When there is a sudden power outage, the valve can automatically close to protect the safety of the water pump and pipeline.

Product technical paramters:

Product features:

1. A small volume, light weight and sturdy, wear-resistant design make it with low fluid resistance and is not easily clogged.
2. A short structural length, compact overall structure and simple design for good sealing performance and flexible operation. The valve disc can be used multiple times and has a long service life.
3. Double flange connection, with a simple structure and convenient installation and use.
Under high flow pressure conditions, the rubber disc check valve operates smoothly with an amplitude not exceeding 0.5mm.
4. All materials used to manufacture rubber disc check valves are suitable for corrosive environments in various parts of water supply engineering.
5. The rubber disc check valve adopts a national standard flange, which is convenient and fast to install when matched with the pipeline compensation joint.
6. The special structural form makes the sealing pair less prone to damage and improves the service life of the valve.
7. When the valve is fully open, it is not easy to produce shaking phenomenon. When it is fully closed, it is not easy to deform and damage the sealing ring, causing the entire sealing pair to leak the valve. Moreover, it has a simple and compact structure, light weight, easy operation, and reliable performance,
8 Reliable sealing, with an opening and closing life of over 30000 times and a service life of over 30 years.
9. During the operation, the noise is low and there is no vibration, giving the operator a sense of safety.
10. The valve plate adopts a fully lined rubber structure, which has strong corrosion resistance.
