Watts 41A Safety Relief Valve

Description:

The Watts Model 41A Safety Relief Valve is a 1 in. x 1-1/4 in. ASME Section VIII safety relief valve designed to provide automatic overpressure protection for air, gas, and vapor systems with a set pressure of 100 PSI and a rated capacity of 666 SCFM. Commonly installed on air compressors, receivers, intercoolers, aftercoolers, gas burners, pneumatic conveying equipment, dryers, and pressure vessels requiring reliable pressure relief protection. Maintenance technicians, compressor service contractors, OEMs, and system integrators use this valve for safety compliance, replacement projects, preventive maintenance, and new installations requiring dependable overpressure protection.

Applications:

The Watts Model 41A Safety Relief Valve is widely used in compressed air systems, air compressor packages, receiver tanks, intercoolers, aftercoolers, pneumatic conveying systems, industrial dryers, gas-fired equipment, manufacturing facilities, process plants, chemical processing operations, food and beverage production facilities, utility systems, pressure vessels, and industrial piping networks. The valve automatically opens when system pressure exceeds the set point, protecting equipment from potentially damaging overpressure conditions while helping maintain compliance with ASME safety requirements. It is commonly specified in commercial and industrial environments where reliable pressure relief protection is essential for personnel safety, equipment protection, and operational reliability.
