Signal Flange Gate Valve

This valve is manufactured in China and fully compliant with Chinese national fire safety standards. It has passed rigorous quality and safety testing, including CCCF (China Compulsory Certification for Fire Products), ensuring reliable performance and long service life. While it is certified for the Chinese domestic market, it meets international design and quality specifications and can be used in many projects worldwide where local certification is not mandatory.

Core Advantages of Flanged Non-Rising Stem Signal Gate Valve

----------------------------------------
Non-Rising Stem Flanged Resilient Seated Signal Gate Valve (Z45X-16Q / XZ45X-16Q)

• Signal Feedback Function for Remote Monitoring & Safety Management--The Z45X-16Q non-rising stem flanged signal gate valve is equipped with a signal feedback device. It transmits real-time open/closed status signals of the valve to the control system, realizing remote status monitoring. No on-site manual inspection is required, perfectly matching fire alarm linkage systems for building fire protection pipelines.

• Flanged Connection for Stable, Reliable Assembly--Designed with standard flanged ends, this resilient seated signal gate valve achieves firm, leak-free connection with pipelines. Convenient disassembly and maintenance make it adaptable to municipal water supply, underground pipe galleries and large-scale fire water pipeline projects. The connection structure withstands long-term pipeline vibration.

• Compact Non-Rising Stem Structure, Space-Saving Layout--Adopting the non-rising stem (NRS) design, the valve stem does not extend outward during opening. It occupies less vertical installation space, ideal for limited-space conditions such as basement pipe trenches and overhead piping, solving installation restrictions of traditional rising stem gate valves.

• Full Bore Straight Channel, Low Fluid Resistance--Built with a full through bore flow path, the signal flanged gate valve avoids medium deposition and flow dead zones. It guarantees low pressure loss during medium circulation, suitable for long-term continuous delivery of fire water, domestic tap water and circulating water systems.
