The CARLIN VALVE is a superior quick-connect and attack tool from Fyrelane USA. By letting you quickly hook up to the hydrant and put manpower and equipment on the fire faster and safer, you increase the efficiency of your fire fighting personnel. Attach it to the hydrant, turn it on, and water automatically starts flowing at 5 to 10% of capacity. This allows the operator to reach and set pressure at the pumper. Fire fighters are free to accompany the pumper to the fire because the CARLIN VALVE eliminates hydrant flow decisions. Because it is automatically activated by water pressure, no motors, batteries or radios are needed for remote operation. It prevents committing hose load to a dry or out-of-service hydrant. The CARLIN VALVE helps protect your personnel as well because it effectively controls the flow of water to virtually eliminate dangerous water hammer.
