How does a non-rising stem elastic seat gate valve work

Jul 5, 2023 | News

China’s renowned big size gate valve manufacturer has unveiled its latest innovation – the non rising stem resilient seated gate valve, specifically designed for big size applications. This groundbreaking valve is set to revolutionize fluid control systems with its exceptional performance and reliability.

Non-rising stem elastic seat gate valve is a kind of gate valve with special structure.

It features a non-rising stem design that does not rise or fall during opening and closing, thereby reducing operating force and friction. Flexible seat gate valve with good sealing performance and wear resistance, suitable for high pressure, high temperature and corrosive media fluid control. It is widely used in petrochemical, electric power, metallurgy and other industries.

Non-rising stem elastic seat gate valves work as follows:

When the operator rotates the handle or electric device, the valve stem moves the valve plate upward by transmitting force. At the same time, the elastic seat on the valve plate is separated from the valve seat, opening the fluid passage. Fluid can flow freely through the valve.

When the operator rotates the handle or electric device, the valve stem moves the valve plate downward by transmitting force. The elastic seat on the valve plate is in contact with the valve seat and prevents the passage of fluid. The valve is completely closed and a good seal is formed between the valve plate and the valve seat ring.

Non-rising stem Elastic seat Gate valves control the opening and closing of the door plate through the rotating motion of the stem. Fluid control is achieved by the contact and separation of the elastic seat on the valve plate from the valve seat. The valve has good sealing performance and wear resistance, and is suitable for fluid control of high pressure, high temperature and corrosive media.

The non-rising stem resilient seated gate valve

Developed by the leading Chinese company, is engineered to meet the demanding requirements of various industries, including water supply, wastewater treatment, and irrigation. With its robust construction and superior functionality, this valve offers a reliable and efficient solution for controlling the flow of fluids in large-scale applications.

One of the key advantages of the non-rising stem resilient seated gate valve is its exceptional sealing performance and durability. The resilient seat ensures a tight seal, preventing leakage and ensuring reliable operation even in harsh operating conditions. The non-rising stem design eliminates the need for vertical space, making it ideal for installations with limited headroom.

Furthermore, the valve’s big size design allows for high flow capacity and low pressure drop, optimizing system efficiency. The non-rising stem gate valve’s resilient seat provides excellent resistance to wear and corrosion, ensuring long-lasting performance and reducing maintenance requirements.
