Frequently Asked Questions

What is an AQUATROL safety relief valve used for?

An AQUATROL safety relief valve protects pressure vessels and steam systems from overpressure. This ASME Section VIII valve automatically opens at its set pressure to vent excess steam, then reseats to prevent system damage. It is commonly used in boilers, pressure cookers, and industrial steam applications.

What are the specifications of the AQUATROL 740DC1M1K1-125 safety relief valve?

The AQUATROL 740DC1M1K1-125 is a 1/2 in MNPT x 3/4 in FNPT bronze safety relief valve with a maximum operating pressure of 364 psi. It is ASME Section VIII certified for steam service. The bronze body resists corrosion in high-temperature environments.

Where to buy AQUATROL safety relief valves worldwide?

How to install an AQUATROL safety relief valve?

Install the AQUATROL valve in a vertical position with the spindle upright. Use pipe dope on the male threads only, avoiding the valve inlet. Ensure the discharge line is unobstructed and directed to a safe location. Never oversize the valve or install a shutoff valve between the vessel and relief valve.
