Product Details

Description

Non-Rising Stem Design

Bubble-Tight EPDM Seal

DIN F4 / EN 1074 / BS 5163

Fusion-Bonded Epoxy Coated

DN50 to DN1400 Available

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.

Opt for this DIN F4-compliant Non-Rising Resilient Seat Gate Valve when a dependable, space-saving shut-off solution is required for demanding infrastructure projects.

Frequently Asked Questions

Q What does "non-rising stem" mean in this gate valve, and why is it beneficial?

A non-rising stem design means the stem does not move upward when the valve is opened or closed — instead, it rotates in place while the wedge travels internally. This eliminates the need for extra vertical clearance above the valve, making it ideal for underground installations, valve pits, and space-restricted environments where overhead room is limited.

Q What standards does this DIN F4 Non-Rising Resilient Seat Gate Valve comply with?

This valve is designed and manufactured in compliance with multiple international standards, including DIN3352 F4/F5 for design, DIN3202 F4/F5 and BS5163 for face-to-face dimensions, DIN2533 PN10/PN16 and ANSI 125/150 for flange drilling, and DIN3230 / BS6755 for testing and inspection. It also meets the performance requirements of EN 1074 and AWWA C509/515.

Q What size range is available for this resilient seat gate valve?

The Non-Rising Resilient Seat Gate Valve is available in a wide range of sizes from DN50 up to DN1400 for standard configurations, with the full specification range extending to DN2200. This broad size availability makes it suitable for both small distribution lines and large-diameter municipal water mains.

Q What materials are used in the construction of this gate valve?

The valve body and wedge are made from either cast iron or ductile iron, with the body coated in fusion-bonded epoxy for superior corrosion resistance. The stem is manufactured from stainless steel or brass, while the sealing ring and O-ring are available in EPDM or NBR rubber. The EPDM-encapsulated wedge provides a fully bubble-tight shut-off even under elevated pressure.

Q Can this valve be operated with an electric actuator?

Yes. This Non-Rising Resilient Seat Gate Valve can be equipped with either a manual handwheel for traditional operation or an electric actuator for automated and remote-controlled applications. This flexibility makes it suitable for both manually operated systems and modern automated water distribution or fire protection networks.

Q What media and temperature conditions is this valve suitable for?

This gate valve is suitable for a wide range of media including water, air, steam, oil, chemicals, acids, and salts. It operates reliably within a working temperature range of -10°C to 120°C and at nominal pressures of PN10 or PN16, making it versatile for municipal water supply, fire protection, irrigation, and various industrial pipeline applications.
