Hale / Class 1 Relief Valve W/ 2-1/2″ NPT

A Hale Relief Valve W/ 2-1/2″ NPT is a specialized valve used in fire pump systems to regulate the pressure of water being pumped. The relief valve is typically installed in the discharge line of the fire pump and is designed to relieve excess pressure by diverting water flow away from the system.

The Hale Relief Valve is designed to open automatically when the pressure in the system exceeds a pre-set limit, allowing water to flow out of the system and preventing damage to the pump and other components. The 2-1/2″ NPT connection allows the valve to be easily installed in the discharge line of the pump system.

The Relief Valve is an important component of a fire pump system because it helps to ensure that the system can deliver water at the correct pressure and flow rate to extinguish fires effectively. The valve is available in a range of sizes and configurations to meet the needs of different fire protection systems.

Proper installation, maintenance, and testing of the Relief Valve is essential to ensure that it is functioning correctly and providing reliable operation of the fire pump system. Regular inspection and maintenance of the fire pump system can help identify issues with the Relief Valve and other components before they become major problems.

Here are the general steps to test a Hale Relief Valve:

1. Prepare for the test: Before testing the valve, ensure that the pump is turned off and that the system is depressurized. Also, make sure that the relief valve is properly installed and connected to the discharge line of the pump.
2. Test the valve manually: To test the valve manually, slowly open the valve by turning the adjustment screw counter-clockwise until water begins to flow out of the valve. Let the water flow for a few seconds, then close the valve by turning the adjustment screw clockwise until the water flow stops. This test will help to ensure that the valve is functioning properly and that it is not stuck in the closed position.
3. Test the valve with a gauge: To test the valve using a gauge, install a pressure gauge downstream of the valve and slowly increase the pressure in the system to the point where the valve should open. The pressure at which the valve opens should be within the manufacturer’s recommended range. If the valve does not open at the correct pressure, it may need to be adjusted or replaced.
4. Record the results: After testing the valve, record the results in the system’s maintenance log. This information can be used to track the performance of the valve over time and to identify any issues that may need to be addressed.

It is important to consult with a qualified technician or service provider with experience working on fire pump systems to ensure that the test is performed correctly and that the valve is functioning properly. Regular inspection, maintenance, and testing of fire pump systems can help identify issues before they become major problems, reducing the likelihood of downtime and ensuring reliable operation in the event of a fire.
