The ZRIN-D41 Resilient Seated Flanged Gate Valve is a high-performance industrial solution engineered for superior sealing reliability. By integrating a metal-to-soft seal design—featuring a rubber-lined wedge against a metal seat—this valve ensures a bubble-tight shut-off, making it an ideal choice for fluid control in demanding environments where leakage prevention is critical.
Specifically designed for versatility, the ZRIN-D41 is widely deployed in wastewater treatment, drinking water supply systems, and large-scale irrigation projects. Its robust construction, combined with professional epoxy coating, ensures long-term durability and resistance to corrosion, providing a reliable flow control mechanism for modern industrial piping networks.

| Application Suitability | Water/Wastewater Systems | Low-Pressure Piping |
A Resilient Seated Gate Valve is a valve featuring a rubber-lined wedge. This "soft seal" provides a tighter closure than metal-to-metal valves, making them ideal for drinking water and wastewater applications.
For ZRIN-D41 Flanged Gate Valves, we apply a high-quality epoxy coating to ensure maximum resistance against corrosion and environmental wear.
No. Because the resilient seat uses non-metallic elastic materials, it is not suitable for high-temperature environments as the soft seal can wear down or deform.
The primary difference is the installation: Flanged valves are bolted to piping flanges, providing easier replacement and a different connection method compared to the socket-fit design.
We offer several material options including Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), and Stainless Steel (SS) to meet various industrial requirements.
The ZRIN-D41 follows DIN 3352 for design, DIN 3202 F4/F5 for face-to-face dimensions, and DIN 2501 for flange drilling.
