Internal screw lift check valve (H11W-25P)

H11W internal thread lift check valve structure is generally similar to the globe valve, the valve disc along the channel to the line for lifting movement, the valve body is: 304, 316 and other stainless steel, is silica sol precision casting, used to prevent the media backflow.

How it Works 】 :

H11W internal thread lift check valve When the medium flows into the valve body as shown by the arrow of the valve body, the pressure of the medium acts on the valve disc to produce upward thrust, when the medium thrust is greater than the gravity of the valve disc, the valve opens. When the force of the medium pressure acting on the valve disc and the gravity of the valve disc itself is greater than the force acting on the valve disc by the pressure in front of the valve, the valve is closed to prevent the backflow of the medium.

【 Product Features 】 :

1, simple structure, small size, light weight.

2, easy maintenance, unloading and replacement are more convenient.

3, a variety of thread types: G·NPT.BSPT.BSP DIN259/2999 available.

4, the flow path is smooth, the fluid resistance is small, the valve disc can be fully opened under a small pressure difference.

H11W internal thread lift check valve is silica sol cast stainless steel body. Reasonable structure, beautiful shape. The seat adopts elastic sealing structure, easy to open and close and reliable sealing. It is used to prevent the backflow of media in the pipeline. Applicable media: water, oil, steam, acid media, etc. The valve is installed on the horizontal pipe and can automatically prevent the flow back
