Stainless Steel Check Valve

Category Check Valve

The main material of the valve is stainless steel, precision casting technology, swing type hard seal structure, the valve opening and closing pressure is small, the fluid resistance is small.

Nominal Diameter	1.6/2.5MPa
Applicable temperature	0~150°C
Applicable medium	Water, steam, oil, weakly corrosive media

Process Description

Stainless steel is used as material to form the basic shape of the valve. The valve then goes through the process of casting, Solution Treatment, Pickling and Passivation, Machining, Ultrasonic Cleaning, Assembly, Pressure Testing, Drying, Packaging, and Storage. With a final inspection, the valve will be packaged and sent out

Feature

1.Only allow the medium to flow in one direction, suitable for small diameter pipes to prevent the backflow of the medium.

2. The disc opens or closes by itself depending on the flow of the medium, the kinetic energy of the fluid and the weight of the disc.

3. The lock shaft is connected with the valve disc with built-in structure, which has excellent performance and more reliable sealing.

4. The product is installed horizontally to ensure sensitive and reliable action.

5. Suitable for heating, air conditioning, petroleum, chemical, pharmaceutical, metallurgy, electric power industry and other working conditions of the pipeline.
