Teledyne Farris WL23-1 Pressure Relief Valve

Description:

The TELEDYNE FARRIS 1890L Pressure Relief Valve is used to protect pressurized liquid systems from overpressure by automatically relieving excess pressure when the set pressure of 115 PSIG is reached. Commonly installed in pumps, pressure vessels, process piping, hydraulic systems, chemical processing equipment, water treatment systems, and other industrial liquid service applications requiring ASME-certified overpressure protection. Maintenance technicians and system integrators use this relief valve for repair, retrofit, replacement, and preventive maintenance of industrial process and safety systems.

Applications:

The TELEDYNE FARRIS 1890L Pressure Relief Valve is commonly used in liquid process systems, chemical plants, refineries, water and wastewater treatment facilities, power generation plants, food and beverage processing, pharmaceutical manufacturing, hydraulic systems, pressure vessels, storage tanks, and industrial piping systems where reliable overpressure protection is required.
