Frequently Asked Questions

A pressure relief valve is a safety device that automatically releases excess pressure from a system to prevent damage or failure. It is crucial for protecting plumbing, HVAC, and other systems from overpressure situations.

We offer a variety of pressure relief valves, including spring-loaded, diaphragm, and adjustable models, suitable for various HVAC and hydronic systems.

The appropriate pressure relief valve depends on the pressure rating and flow requirements of your system. Refer to product specifications or consult with customer support to find the right valve for your needs.

While installation is straightforward, it is essential to follow the manufacturer’s instructions carefully. If unsure, it’s best to consult a professional to ensure safe and proper installation.

Regular maintenance involves inspecting the valve for leaks, ensuring it functions properly under pressure, and cleaning it to remove any debris. It’s also important to test the valve periodically to ensure it activates at the correct pressure level.
