    Description

    Rising Stem Design
    Solid Wedge Gate
    EN 1074 / BS 5163
    EPDM Encapsulated
    Epoxy Coated Body

    Rising Stem Solid Wedge Gate Valve is engineered for applications where both visual valve status and secure shut-off are required. The rising stem design allows users to easily observe whether the valve is open or closed, making it ideal for fire protection systems, municipal water supply, and irrigation networks.

    This valve features a solid wedge gate, which delivers a reliable bidirectional seal even under fluctuating pressure conditions. Its ductile iron body is coated with epoxy for excellent corrosion resistance, while the fully encapsulated EPDM rubber wedge ensures long-lasting performance.

    Our Rising Stem Solid Wedge Gate Valve supports manual or actuator-based operation and is available in a wide range of pressure classes and sizes. The visible stem movement provides quick operational feedback, which is especially valuable in emergency systems and maintenance scenarios.

    As one of China's trusted valve manufacturers, we ensure each Rising Stem Solid Wedge Gate Valve meets international quality standards like EN 1074 and BS 5163. Whether used above ground or in accessible underground chambers, this valve offers strength, visibility, and durability.

    Choose our Rising Stem Solid Wedge Gate Valve for dependable flow control backed by quality construction and a proven track record in critical applications.

    Frequently Asked Questions

    Q What is the advantage of a rising stem design in a gate valve?
    The rising stem design provides a clear visual indication of the valve's open or closed position. As the handwheel is turned, the stem visibly rises or descends, allowing operators to instantly confirm valve status without additional instrumentation — especially useful in emergency systems and maintenance operations.
    Q What international standards does this Rising Stem Solid Wedge Gate Valve comply with?
    Our Rising Stem Solid Wedge Gate Valve is manufactured to comply with internationally recognized standards including EN 1074 and BS 5163. These certifications ensure the valve meets stringent performance, pressure, and safety requirements for water supply and fire protection applications.
    Q What are the typical applications for this valve?
    This valve is widely used in fire protection systems, municipal water supply networks, irrigation systems, and industrial pipelines. It is suitable for both above-ground installations and accessible underground chambers where visual stem monitoring is required.
    Q Can this valve be operated with an actuator?
    Yes. The Rising Stem Solid Wedge Gate Valve supports both manual handwheel operation and actuator-based operation. This makes it versatile for automated control systems as well as traditional manual installations across various pressure classes and pipe sizes.
    Q What materials are used in the construction of this gate valve?
    The valve body, disc, bonnet, yoke, and handwheel are made from ductile iron with epoxy coating for corrosion resistance. The seat and bonnet gasket use EPDM rubber for reliable sealing. The shaft is SS420 stainless steel, the wedge nut is brass, and the packing material is flexible graphite for high-performance sealing.
    Q How does the EPDM encapsulated wedge benefit long-term performance?
    The fully encapsulated EPDM rubber wedge provides a tight, bidirectional seal that remains effective even under fluctuating pressure conditions. EPDM is highly resistant to water, weathering, and chemical exposure, which significantly extends the service life of the valve and reduces maintenance requirements.
