DIN Standard Non-Rising Stem Flanged Gate Valve

German Standard Gate Valve is a valve that complies with German Industrial Standards (DIN) and is widely used in industries such as petroleum, chemical, power, and metallurgy.  It is a type of valve used to cut off or connect media in pipelines. It has the characteristics of simple structure, good sealing performance, low flow resistance, and easy operation. It is suitable for various working conditions, especially for environments with high temperature, high pressure, and corrosive media.

Core Advantages of Flanged Non-Rising Stem Resilient Gate Valve DIN

----------------------------------------

• Non-Rising Stem Design & Space-Saving Operation--The Z45X-16Q non-rising stem (NRS) flanged resilient seated gate valve adopts an internal concealed stem structure. The stem only rotates without vertical displacement when opening and closing. It greatly saves vertical installation space, perfectly suitable for underground buried pipelines, pipe trenches, low clearance pipe rooms and municipal water supply compact piping conditions.

• Standard DIN Flanged Connection & Reliable Assembly--Designed in accordance with DIN standard flanged end, the valve body is manufactured from ductile iron QT450 (GGG50). Standard flange dimensions enable convenient interchangeable installation with DIN pipeline fittings. No special adapter is required, simplifying project piping design and shortening on-site construction cycle for municipal waterworks, sewage treatment and building water supply systems.

• Full Bore Flow & Anti-Sediment Structure--Adopting full-port straight through flow channel, this resilient seated gate valve avoids flow dead zones and turbulence. Medium flows smoothly without sediment deposition and blockage risks, supporting stable long-term service for drinking water, reclaimed water and general industrial water pipeline networks.

• Zero-Leakage Resilient Sealing & Long Service Stability--Fitted with EPDM rubber encapsulated wedge, the valve realizes bidirectional bubble-tight shut-off under PN16 (1.6MPa) working pressure. Excellent sealing performance, outstanding pressure resistance and anti-ageing property guarantee reliable cut-off function for municipal water supply projects, water treatment plants and building plumbing systems.
