Non Rising Stem Gate Valves

Hanno Valve offers high quality Non Rising Stem Gate Valves for tight spaces and limited-installation environments. As a trusted China manufacturer and supplier, Hanno Valve produces durable Non Rising Stem Gate Valves with the stem hidden inside the valve body. This space-saving design reduces interference from external factors, extends service life, and is especially suitable for small pipelines, low-viscosity fluids, and applications where installation space is strictly limited.

Hanno Valve Non Rising Stem Gate Valves are particularly suitable for applications where installation space is limited, high sealing performance and ease of operation are required, such as small piping systems or where installation space is strictly limited.

1. Working Principle of Non Rising Stem Gate Valves

Non Rising Stem Gate Valves are devices that open and close valves by rotating the valve stem. When the valve stem rotates upwards, the valve disc rises accordingly, opening the fluid channel; when the valve stem rotates downwards, the valve disc descends and closes the fluid channel. Due to the metal seal between the valve disc and the valve seat, the concealed stem gate valve has good sealing performance. In addition, the opening and closing torque of the concealed stem gate valve is relatively small, making it easy to operate and suitable for various environments and usage scenarios.

2. Structural Characteristics of Non Rising Stem Gate Valves

① Valve body: The valve body of Hanno Valve Non Rising Stem Gate Valves is usually made of materials such as cast iron, cast steel, or stainless steel, which have high strength and corrosion resistance. There is a fluid channel inside the valve body, and the inlet and outlet of the channel are connected to the pipeline.

② Valve disc: The valve disc is a key component of a concealed stem gate valve, used to control the opening and closing of fluid channels. The valve disc is usually made of the same material as the valve body, with good sealing performance and wear resistance.

③ Valve stem: The valve stem is a component that connects the valve disc and the handle, and drives the opening and closing of the valve disc by rotating the valve stem. Valve stems are usually made of high-strength materials such as stainless steel to ensure good corrosion resistance and a longer service life.

④ Sealing structure: The sealing structure of a concealed stem gate valve mainly consists of a valve disc and a valve seat. The valve seat is usually made of elastic materials such as rubber or polytetrafluoroethylene (PTFE) to ensure a tight fit between the valve disc and the valve seat, thereby achieving a good sealing effect.

FAQ

Q: What is the main advantage of a Non Rising Stem Gate Valve over a Rising Stem design?

A: The primary advantage is space savings. Since the stem does not rise, Non Rising Stem Gate Valves require no vertical clearance, making them ideal for underground pipes, tight equipment rooms, and small pipeline systems.

Q: Are Hanno Valve Non Rising Stem Gate Valves suitable for high-temperature applications?

A: Yes, depending on the material selection. Stainless steel and cast steel options can handle elevated temperatures. Please consult Hanno Valve for specific temperature ratings based on your application.

Q: Can these valves be used with corrosive fluids?

A: Absolutely. Hanno Valve offers Non Rising Stem Gate Valves in corrosion-resistant materials such as stainless steel, with PTFE seats that provide excellent chemical resistance.

Q: Where can I purchase Hanno Valve Non Rising Stem Gate Valves?

A: You can contact Hanno Valve directly to request quotes, product catalogs, technical datasheets, or bulk purchase options. As a China manufacturer and supplier , we offer competitive pricing and worldwide shipping.
