Signal Grooved Butterfly Valve with Worm Gear

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.

Worm Gear Grooved Signal Butterfly Valve (XD381X-16Q)

• Labor-Saving Worm Gear Operation & Self-Locking Positioning – The XD381X-16Q worm gear grooved signal butterfly valve adopts worm gear transmission structure to greatly reduce operating torque. The self-locking mechanism holds the valve steadily at any opening position. It supports frequent switching and flow adjustment, ideal for fire protection, water supply and HVAC grooved pipeline systems.

• Compact Integrated Grooved Structure, Quick Weld-Free Installation – This signal butterfly valve features compact, lightweight body with short face-to-face dimension. Standard grooved ends enable fast field assembly without welding. It occupies minimal space and adapts well to narrow pipe galleries and ceiling piping in fire fighting networks.

• Bubble-Tight EPDM Resilient Sealing & Long Service Life – Equipped with high-performance integrated EPDM seat, the valve maintains reliable zero-leak sealing under low-pressure conditions. The anti-ageing, wear-resistant sealing system delivers consistent tightness for long-cycle operation of fire sprinkler and domestic water pipelines.

• Streamlined Valve Disc for Low Flow Resistance – The hydrodynamically optimized streamlined disc cuts fluid turbulence and pressure loss. A large effective flow area is available when fully open, improving water delivery efficiency for circulating water and fire service piping.

• Real-Time Signal Feedback for Intelligent Fire Monitoring – Fitted with high-sensitivity micro signal switches, the valve feeds back full-open/full-closed status to fire control systems instantly. It enables remote valve status monitoring and meets intelligent management requirements of building fire protection engineering.
