Gate Valve

  • Double Flange High-Pressure Gate Valve GOST Russian Standard Sluice Gate Valve
    Double Flange High-Pressure Gate Valve GOST Russian Standard Sluice Gate Valve
    Brief:
    Cast iron rising stem gate valve is mainly used as a shut-off valve in water supply, heating, cooling, drainage, irrigation and general industrial pipeline systems. The valve adopts a rising stem structure. When the valve is opened, the stem rises upward, allowing the operator to clearly check the open or closed position of the valve. The valve is connected to the pipeline by flanges and operated manually by handwheel. It is suitable for full open or full close service and is not recommended for long-term throttling operation.

  • Flanged Resilient OS&Y Gate Valve
    Flanged Resilient OS&Y Gate Valve of FM UL Osy Gate Valves for Fire Fighting Pipe Fitting
    Brief:
    Flanged Resilient OS&Y Gate Valve is mainly used for fluid control in pipeline systems and can effectively open or close the flow in the pipeline. It operates the gate by rotating the valve stem. OS&Y stands for "Outside Screw and Yoke", which means the valve stem is externally designed for easy operation and maintenance. The resilient seat sealing technology ensures that the valve has better sealing when opening and closing to prevent leakage. This valve is commonly used in fire protection systems, water treatment systems and water supply pipelines, and is particularly suitable for applications that require high reliability and durability. Its flange connection method facilitates quick docking with other pipeline components and simplifies installation.
  • BS5163 DIN F4 Flanged Resilient Seated Nrs Gate Valve for Water Supply HVAC Fire Fighting
    BS5163 DIN F4 Flanged Resilient Seated Nrs Gate Valve for Water Supply HVAC Fire Fighting
    Brief:
    NRS Gate Valve
    NRS means Non-Rising Stem. The stem does not move upward when the valve is opened or closed, making it suitable for installations with limited vertical space, such as underground pipelines, valve chambers, pump rooms, and compact piping systems.
    Common types include:
    Flanged NRS Gate Valve
    Grooved NRS Gate Valve
    Resilient Seated NRS Gate Valve
    Post Indicator NRS Gate Valve

  • Flanged Resiliend NRS Gate Valve
    Flanged Resiliend NRS Gate Valve
    Brief:
    Flanged Resilient NRS Gate Valve is mainly used for fluid control in pipeline systems and has reliable switching functions. NRS stands for "Non-Rising Stem", which means that the valve stem remains unchanged during operation, and the valve disc is operated to open or close the flow of the pipeline by rotating the valve stem. The elastic seat seal design ensures that the valve has better sealing performance during the opening and closing process to prevent leakage. This valve is widely used in water supply, fire protection, water treatment and other systems. The flange connection makes it easier to install and maintain, and is suitable for application environments that require pressure resistance, strong durability and high sealing.
