Grooved Rising Stem Gate Valve

Product Features and Applications

Structural Features

Rising Stem Design

In a rising stem gate valve, the valve stem is exposed, moving up and down during operation to raise or lower the gate, thereby controlling the flow of the medium. The position of the stem provides a direct indication of whether the valve is open or closed, making it ideal for applications where clear indication of valve status is required.

Grooved Connection

Utilizing a grooved connection method, installation only requires connecting the valve to the pipeline using grooved couplings, eliminating the need for welding or flange connections. This allows for quick and easy installation, making it particularly suitable for on-site construction and rapid installation needs.

Gate Structure

The gate typically features a wedge or parallel double gate design, ensuring excellent sealing performance when closed, effectively preventing medium leakage.

Sealing Materials

The sealing surfaces between the gate and the valve seat use either metal or soft sealing materials (such as EPDM or NBR), effectively preventing leakage and enhancing the valve’s service life

Operation Method

Operated via a manual handwheel or gear operator, the valve’s stem moves up or down during opening or closing, making the operation process intuitive and easy to control.

Performance Features

Visual Indicator of Open/Closed Status

Since the valve stem is exposed, the open/closed status of the valve can be directly observed by the position of the stem. This makes operation simple and intuitive, ideal for situations where quick judgment and operation are required.

Easy Installation

The grooved connection method makes valve installation and removal extremely quick and easy, reducing installation time and labor costs. This is ideal for the rapid construction of large-scale piping systems.

Excellent Sealing Performance

Utilizing a wedge gate or parallel double gate design, the valve ensures excellent sealing performance when closed, making it suitable for piping systems that require high sealing integrity.

High Durability

The valve body and sealing materials are carefully selected and manufactured to ensure long-term use under various conditions, offering excellent corrosion resistance and wear resistance.

Easy Maintenance

The rising stem design keeps the stem threads away from the medium, reducing corrosion and wear, thereby extending the service life. Additionally, maintenance is simplified, as basic inspections and repairs can be performed without removing the valve.

Application Fields

Fire Protection Systems

Used in fire protection water supply pipelines to control the opening and closing of water flow, ensuring that the valve can be quickly opened or closed in the event of a fire.

Water Supply Systems

In urban and industrial water supply systems, grooved gate valves are used to regulate and control water flow, ensuring stable system operation.

Industrial Pipelines

Suitable for pipeline systems in industries such as petroleum, chemical, and metallurgy, it effectively controls the flow of media, meeting the demands of industrial production.

Heating, Ventilation, and Air Conditioning (HVAC) Systems

In HVAC systems, it is used to control the flow of hot and cold water, ensuring the efficient operation of the system.
