Stainless Steel H74w Check Valve

H74H type sandwich check valve main performance and characteristics:

1. For clip-type connection, it can save cost and be affordable.
2. The raft flap has short stroke, small volume and short length.
3. Suitable for narrow space working condition, easy to install.
4. The impact force is small when closed, and the pressure of the water hammer is small.

Working principle:
Is a super thin check valve, it has the advantages of simple structure, beautiful appearance, light weight, convenient installation, etc. Mainly applicable to the water supply system, petroleum, chemical, metallurgy and other industrial sectors, the installation space is more suitable for the place. It's a valve that automatically stops the flow from going back. The disc of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side.

Structure and Use

H74H sandwich check valve is a kind of ultra-thin check valve, it has the advantages of simple structure, beautiful appearance, light weight, easy installation and so on. H74 type Ⅰ, type Ⅱ clamping disc type check valve produced by our factory is a kind of ultra-thin shape check valve, it has the advantages of simple structure, beautiful appearance, light weight, convenient installation and so on. The valve is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors to have installation space limit place is suitable for the most.

Installation should pay attention to the following things:
1. Do not make the check valve bear weight in the pipeline. The large check valve should be supported independently, so that it is not affected by the pressure produced by the pipe system.
2. When installing, pay attention to the direction of the flow of the medium and the direction of the arrow of the valve body.
3. The lifting vertical flap check valve should be installed on the vertical pipe.
4, lift type horizontal flap check valve should be installed on the horizontal pipe.

Features:
1, the valve structure length is short, suitable for the position of narrow space.
2, swing valve disc structure, fluid resistance is small.
3. Depending on the medium pressure, the valve disc is opened under pressure and automatically closed without pressure.
4, suitable for water, steam, oil and so on.

Advantages:
Is a super thin check valve, it has the advantages of simple structure, beautiful appearance, light weight, convenient installation, etc. Mainly applicable to the water supply system, petroleum, chemical, metallurgy and other industrial sectors, the installation space is more suitable for the place.
