      Product Details

      Description
      🔧

      Designed for use in water distribution and fire protection systems, the Non-Rising Resilient Seat Gate Valve conforming to DIN F4 is ideal for underground and space-restricted installations. Its non-rising stem design eliminates the need for extra vertical space, making it well-suited for buried or compact layouts.

      🛡️

      Constructed with a ductile iron body and coated with fusion-bonded epoxy, this valve offers high resistance to corrosion. The fully encapsulated EPDM rubber wedge ensures a bubble-tight seal even under elevated pressure conditions.

      📐

      Built to DIN F4 dimensions, its compact face-to-face length allows for straightforward integration into piping systems that follow European standards. With smooth operation, low torque demands, and reduced maintenance requirements, it is widely favored in municipal and industrial water networks.

      🏭

      Produced by a prominent Chinese valve manufacturer, this Non-Rising Resilient Seat Gate Valve meets the requirements of EN 1074 and BS 5163. Available in sizes from DN50 to DN1400, it can be equipped with either a manual handwheel or an electric actuator.

      Frequently Asked Questions
      ❓What is a Non-Rising Resilient Seat Gate Valve and how does it differ from a rising stem gate valve?
      A Non-Rising Resilient Seat Gate Valve uses a stem that rotates in place without moving upward during operation. Unlike rising stem gate valves — where the stem extends above the handwheel when opened — the non-rising design keeps the overall installed height constant. This makes it especially suitable for underground installations, valve pits, and any application where vertical clearance is limited.
      ❓What does DIN F4 compliance mean for this gate valve?
      DIN F4 refers to the face-to-face dimension standard defined under DIN 3202 F4, which specifies the short face-to-face length for gate valves used in European water supply systems. A DIN F4-compliant valve ensures it can be directly installed as a replacement or new installation in pipelines designed to European standards without requiring additional adapters or modifications.
      ❓What size range is available for the Non-Rising Resilient Seat Gate Valve?
      This valve is available in sizes ranging from DN50 up to DN2200, covering a wide spectrum of pipeline applications. Whether you need a compact valve for a residential water supply line or a large-diameter valve for a major municipal distribution network, the appropriate size can be supplied to match your project specifications.
      ❓What international standards does this valve comply with?
      This Non-Rising Resilient Seat Gate Valve is manufactured in compliance with multiple internationally recognized standards, including DIN 3352 F4/F5 for design, DIN 3202 F4/F5 and BS 5163 for face-to-face dimensions, DIN 2533 PN10/PN16 and ANSI 125/150 for flange drilling, and DIN 3230 / BS 6755 for test inspection. It also meets the performance requirements of EN 1074 and AWWA C509/515.
      ❓Can this gate valve be used with an electric actuator?
      Yes. The Non-Rising Resilient Seat Gate Valve can be equipped with either a manual handwheel for standard operation or an electric actuator for remote or automated control. This flexibility makes it suitable for modern SCADA-integrated water distribution systems and industrial pipeline automation projects where manual operation is not practical.
      ❓What materials are used in the construction of this valve, and why are they chosen?
      The valve body and wedge are made from ductile iron or cast iron, offering excellent mechanical strength and durability. The stem is manufactured from stainless steel or brass for corrosion resistance in wet environments. EPDM or NBR rubber is used for the sealing ring and O-rings, providing reliable sealing performance across a wide temperature range from -10°C to 120°C. The internal and external surfaces are coated with fusion-bonded epoxy to further enhance corrosion protection, particularly for buried or submerged installations.
