API Flange Cast Steel Swing Check Valve

Features:

Size Range: 1/2" up to 30"

Pressure Range: ANSI 150LB to 2500LB

End Connection: BW, RF, RTJ

Material: Carbon Steel

Seals: Metal to Metal Introduction to Swing Check Valve The swing check valve is also called a check valve or check valve, its role is to prevent the medium in the pipeline from flowing backward.

The opening and closing part is opened or closed by the flow of the medium and the force to prevent the medium from flowing backward is called a check valve.

The non-return valve is an automatic valve.

It is mainly used for pipelines where the medium flows in one direction.

It only allows the medium to flow in one direction to prevent accidents.

This type of valve should generally be installed horizontally in the pipeline.

Standards:

Valves Design: BS1868

Face to Face: ANSI B16.10

End Connection: ANSI B16.5, ANSI B16.25

Testing&Inspection : API6D, API598

Suitable Medium: Water, Oil, Air, And Some Corrosive liquid Application of the Ball Check Valve:

The check valves for water is suitable for nominal pressure PN1.0MPa ~ 42.0MPa, Class150-2500; nominal diameter DN15 ~ 1200mm, NPS1 / 2 ~ 48; working temperature - 196 ~ 540 ℃ on various pipelines to prevent Media is flowing backward.

By using different materials (WCB, CF8 (M), CF3 (M), 1Gr5Mo, 15CrMo1V, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea.

It is mainly used for petroleum, chemical, pharmaceutical, fertilizer, power, and other pipelines.

The swing check valve adopts a built-in swing-arm swing structure.

All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body.

Except for the gasket and seal ring in the middle flange, the whole There is no leakage point, preventing the possibility of leakage of the valve.

Swing check valve rocker arm and valve disc adopt a spherical connection structure, so that the valve disc has a certain degree of freedom within a 360-degree range, with appropriate micro-position compensation.

Suitable for clean media, not suitable for media with solid particles and high viscosity.
