The PTFE lined flange check valve SMH44F46-16, except for the valve disc that can be freely raised and lowered, is similar to a globe valve. The fluid pressure lifts the valve disc from the sealing surface of the valve seat, causing the medium to reflux and causing the valve disc to fall back onto the valve seat, cutting off the flow. According to the usage conditions, the valve disc can be made of all metal structure or embedded with rubber pads or rubber rings on the valve disc frame. Like globe valves, the passage of fluid through lift check valves is also narrow, so the pressure drop through lift check valves is greater than that through swing check valves, and the flow of swing check valves is less restricted.

Overview of Semir Products

SMH44F46 swing type fluorine lined check valve is used to control corrosive or highly corrosive media. The surface of the valve body cavity is covered with various fluoroplastics for selection, which have the characteristics of high strength and good corrosion resistance; Suitable for different working temperatures and fluid pipelines to prevent one-way opening and closing of media backflow on various pipelines or equipment.

Working principle of Semir

The valve shaft and disc of the SMH44F46 swing type fluorine lined check valve are designed as one unit, with all fluorine lined plastic shafts embedded in a special groove formed between the valve body and the valve cover, providing flexible opening and closing and reliable sealing. In addition, in addition to the valve body and disc, all reset springs are lined with corrosion-resistant fluoroplastics. A well-designed spring ensures that the disc can also generate sufficient sealing pressure in low-pressure areas, ensuring the reliability of valve sealing in low-pressure areas.

Characteristics of Semir products

1. Suitable for general working conditions and special working conditions with worn or strongly corrosive media.

2. The swing type fluorine lined check valve does not require any additional energy device, reducing operating costs.

3. Good anti backflow effect, utilizing the elasticity of rubber itself and the effect of reverse back pressure.

4. During work, opening and closing are naturally achieved through the pressure difference between the inside and outside, which is a highly corrosive medium and power plant desulfurization.

5. Reliable sealing, especially the new curved valve nozzle, further increases sealing performance, reduces leakage or has no leakage.

6reasonableThe design features allow solid particles to pass smoothly through the valve, and even utilize the flexibility of the body to wrap the solid particles to ensure sealing.
