Rising Stem Design Resilient Seat Gate Valve

The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 degrees when the medium temperature is not high.Structural characteristics：Valve stem exposed: The valve opening can be determined by the lifting height of the valve stem.

Soft sealing materials, such as EPDM (ethylene propylene diene monomer rubber), NBR (nitrile rubber), etc., are corrosion-resistant and have good sealing performance.

Flange connection: commonly used in pipeline flange installation, easy to maintain

What are advantages of Rising Stem Design Resilient Seat Gate Valve?

Good sealing performance: Soft sealing materials can effectively prevent leakage, especially suitable for media such as water and gas.

Intuitive operation: The clear stem design facilitates observation of valve status.

Corrosion resistance: suitable for corrosive media such as water treatment and chemical industry.

Please note some precautions for using the Rising Stem Design Resilient Seat Gate Valve:

Not suitable for high temperature and high pressure: Soft sealing materials usually have a temperature resistance of ≤ 80 ° C (depending on the material), and metal hard seal gate valves should be selected for high pressure conditions.

Avoid particulate media: Solid particles may damage the soft sealing surface.
