Fire Sprinkler System Grooved Signal Butterfly Valve

The grooved fittings for fire fighting system include a grooved butterfly valve with a gear actuator and anti-tamper switch,The JOEPAI 's Fire Sprinkler System Grooved Signal Butterfly Valve represents a significant advancement in fire protection technology, combining efficient grooved connection design and a signal gear box. The valve is fully open or closed when the disc is rotated a quarter turn.The Grooved signal butterfly valve is a grooved clamp connection valve designed completely based on the principle of symmetry. It is symmetrical in the axial centerline, radially centerline, two-way full pressure seal, with a signal device, which can give the valve action. It is mainly used in various pipelines of water supply and drainage, building fire protection and other systems, especially in Fire Protection Systems fittings, to cut off and adjust the flow of the medium.

Technical Specifications and Design Features

The Fire Sprinkler System Grooved Signal Butterfly Valve utilize grooved-end connections compatible with standard coupling systems, significantly reducing installation time compared to traditional flanged or threaded connections. Available in sizes from DN50 to DN300 (2" to 12"), the signal butterfly valves maintain pressure ratings of PN16, suitable for most fire sprinkler system requirements. The grooved butterfly valves operate effectively within temperature parameters of -10°C to 120°C, accommodating various environmental conditions encountered in fire protection applications.A fire butterfly valve primarily consists of a disc, stem, sealing ring, and housing. A telescopic gasket is located between the stem and disc to effectively mitigate wear during valve opening and closing.

Application Scenarios and Installation Guide

The Fire Sprinkler System Grooved Signal Butterfly Valve serves essential functions across diverse fire sprinkler system configurations where reliable flow control and position verification are crucial. Before using a fire butterfly valve, remove any debris to ensure proper opening and flow control. Operators should pay attention to the valve's opening and closing direction, typically marked with "open" and "closed." Open indicates clockwise rotation, while close indicates counterclockwise rotation. When closing a butterfly valve, be especially careful not to twist the valve too hard to avoid breaking the stem and causing unnecessary damage.When using a fire butterfly valve, you need to pay attention to a number of precautions. First, before use, check that the fire water source and pipelines are properly unobstructed. Second, when extinguishing a fire, pay special attention to the opening and closing of the valve to avoid excessive water inflow and insufficient water outflow, which can affect the firefighting effect. Finally, fire butterfly valves need to be inspected regularly to ensure proper operation.

Proper installation requires careful planning and execution to ensure optimal performance and reliable signal transmission. Fire protection engineers recommend installing the grooved signal butterfly valves with adequate clearance for operation and maintenance access to both the valve mechanism and electrical connections. The fire sprinkler valves should be supported independently near the grooved connections to prevent stress transmission to the valve body. Installation teams must verify proper alignment with connecting piping and ensure electrical connections are properly sealed and protected from environmental factors. The signal butterfly valves require correct wiring to fire alarm control panels according to manufacturer specifications and local electrical codes. Regular maintenance protocols for these grooved butterfly valves include quarterly visual inspections, annual operational testing, and verification of signal transmission accuracy to ensure continuous system reliability.

Maintenance and Care

To ensure the normal operation of the fire butterfly valve, it is essential to perform regular inspections and maintenance. During inspection, special attention should be paid to the condition of the valve seat and sealing ring. If any damage or wear is found on the valve seat or sealing ring, they must be promptly replaced. To prevent rust and corrosion, apply antirust oil or kerosene if the fire butterfly valve remains unused for an extended period. After long-term storage, the valve should be periodically operated to prevent seizing or difficulty in opening.
