Butterfly Valve wıth Supervisory Switch

Butterfly Valve wıth Supervisory Switch is a regional control valve used as a shut-off or control valve on water supply lines. It is used to separate zones within indoor areas. The positions of valves in fire systems must be visible and electrically monitored. These valves feature a gear-operated handwheel, with a monitoring switch inside the valve and an open/closed position indicator.

Check Valve

Check valves play a critical role in fire systems by preventing water backflow. These valves can be installed both vertically and horizontally, allowing water to flow in only one direction, thereby protecting equipment and preventing financial losses. With threaded, wafer, flanged, and grooved connection options, they adapt to various applications. The working pressure of check valves ranges from 175psi to 350psi, and they can operate at a maximum temperature of 120ºC. They are commonly used in pump discharge lines, fire department connections, and vertical fire riser systems.

Flow Switch

Flow switches play a critical role in fire detection and suppression systems. These devices detect water flow between 4 and 10 GMP, sending information to the fire control panel and activating the pump. Typically pedal-operated, flow switches are used exclusively in wet pipe systems and can be mounted with threaded fittings or U bolts. They operate at pressures of 400-450 PSI and temperatures between 0 and 49°C. By detecting water flow, flow switches ensure the system functions correctly, although they are limited to wet pipe systems only.

Test Drain Valve

Test and Drain Valve is a critical component for assessing the effectiveness of fire suppression systems. It is used to evaluate whether the system functions correctly after installation and during its use. This valve facilitates system testing, allowing for performance checks after maintenance and repairs. It ensures that the system operates efficiently during a fire, verifying the proper delivery of water and pressure. Essential for testing water flow and pressure, the valve helps identify and rectify any system deficiencies. Therefore, Test and Drain Valves are indispensable for ensuring the reliable performance of fire protection systems.
