Three-in-One Check Valve for Water Steam Oil ISO Certified

Highlight: Three-in-one Check Valve

Product introduction:

The three-in-one check valve is a valve device applied to water supply and drainage systems in buildings and factories, as

well as the outlet of boiler pipeline pumps. It is mainly used to prevent water hammer impact caused by medium backflow

when the pump stops running. This valve integrates the triple functions of a globe valve, check valve, and balance valve. It

achieves silent closing through a spring-preclosed valve disc, is equipped with a nitrile rubber gasket to ensure zero leakage,

and has a built-in stainless steel spring to enhance corrosion resistance. The valve adopts a streamlined structure to reduce

pressure loss and supports installation in horizontal or vertical pipelines. The built-in opening indicator can adjust the pump

output in real time, and medium cutoff or bypass water diversion recovery is realized through the rotation of the valve stem.

Its flange connection design is compatible with pipelines of DN40-1200mm, with the applicable medium temperature

reaching up to 250℃ and the nominal pressure covering 1.0-4.0MPa. The core components include a copper alloy valve

disc, 2Cr13 stainless steel valve stem, and ductile iron valve body, which meet the protection needs of various industrial

scenarios such as building water supply and drainage systems and boiler condensate water systems.

Product technical parameters:

Product features:

1. The output of the pump can be adjusted by regulating the opening degree.

2. An indicator is equipped to visually confirm the valve's opening degree.

3. The gasket is made of nitrile rubber, thus ensuring no leakage at all and being able to absorb impact force.

4. The spring is made of stainless steel, so it has strong corrosion resistance.

5. It can save equipment materials and costs for water consumption and reduce installation space.

6. Due to the streamlined shape and structure, the pressure drop is very small.

7. As it functions as a bypass, it has the function of recycling water in the pipeline on the outlet side, and can supplement

water when a vacuum occurs on the inlet side.

8. It can be installed on both horizontal and vertical pipelines.
