CE Certification German Standard Elastic Seat Gate Valve Manufacturers, Manufacturer
Product Description
Product Features
1. Non-Rising Stem Design
This design allows for space-saving installation, as the stem does not extend vertically when opening or closing the valve. It is especially beneficial in applications with limited vertical space.
2. Durable and Long-Lasting Performance
These valves are made with high-quality materials, ensuring durability and longevity even in demanding environments. They are built to withstand high pressures and maintain reliable performance over time.
3. Easy to Operate and Maintain
Non-rising stem gate valves are designed for easy operation, requiring minimal effort to open or close the valve. Additionally, their simple construction makes maintenance and repairs hassle-free.
4. Space-Saving Installation
The non-rising stem design eliminates the need for vertically extending stems, making these valves ideal for installations with limited space, such as underground or in compact piping systems.
5. Suitable for Low-Profile Installations
Due to their compact design, non-rising stem gate valves are well-suited for applications where a low-profile valve is required. They can be installed in tight spaces without compromising functionality.

Frequently Asked Questions
FAQ What is the advantage of a Non-Rising Stem (NRS) gate valve compared to a Rising Stem valve?
A non-rising stem valve features an internally threaded stem where the gate moves upward inside the body while the stem stays stationary vertically. This compact design is ideal for locations with limited vertical headroom, such as underground pipelines, trenches, and confined utility chambers.
FAQ What pipeline connection and face-to-face standards are supported?
The valves conform to comprehensive international standards including AWWA C509/C515, BS5163, DIN3202 3352 (F4/F5), SABS663, AS, KS, and GOST, fitting flanges from PN6 to PN25, JIS 5K through 16K, ANSI 150LB, and AS2129 Table D/E.
FAQ What fluid media can this valve handle?
Thanks to multiple body and seat material configurations (including Ductile Iron GGG40/50, NBR, EPDM, and FKM), the valve is suitable for fresh water, sea water, oils, natural gas, mild acids, food processing, and steam across temperatures ranging from -50ºC to 250ºC.
FAQ What actuator and operation methods are available?
The valves can be operated manually via standard handwheel or operating cap, mechanically via gearbox, or automated using electric, pneumatic, or hydraulic actuators through an optional ISO 5211 direct-mounting flange.
FAQ What size ranges and pressure ratings are available?
Standard manufacturing sizes range from DN40 up to DN1200, supporting working pressure ratings of PN10, PN16, and PN25 depending on piping requirements.
