Aquatrol 740DD1P1L1 740 Safety Relief Valve (1/2", 40 psig)

The Aquatrol 740DD1P1L1 740 Safety Relief Valve is a high-quality, pressure-relieving device designed for reliable and efficient operation in a wide range of applications. This compact, yet robust valve is engineered to provide safety and peace of mind by automatically releasing excess pressure when it reaches a preset level, preventing potential system failure or damage.

With a nominal size of 1/2", this relief valve is ideal for small to medium-sized systems. Its working pressure is rated at 40 psig (pounds per square inch), making it suitable for applications where the operating pressure falls within this range. The valve body is constructed from durable brass for long-lasting resistance to corrosion and wear.

The 740DD1P1L1 model features a spring-loaded direct-acting diaphragm design that ensures quick and precise pressure relief. The valve is equipped with a pressure-sensitive spring, which allows for easy adjustment of the set pressure. The adjustment knob is located on the top of the valve, providing easy access for routine maintenance and pressure setting.

In addition to its reliable performance, the Aquatrol 740DD1P1L1 740 Safety Relief Valve is also designed for easy installation. The valve comes with a 1/2" NPT (National Pipe Thread) male inlet and a 1/2" NPT female outlet, allowing for quick and secure connection to plumbing systems. The valve is also equipped with a built-in drain port for easy removal of any accumulated water or debris.

In summary, the Aquatrol 740DD1P1L1 740 Safety Relief Valve is a reliable, easy-to-install, and easy-to-maintain pressure relief device ideal for small to medium-sized systems operating at 40 psig. Its durable brass construction, quick-acting diaphragm design, and easy-to-adjust pressure setting make it an excellent choice for applications that require dependable pressure relief and system safety.
