Relief Valves

Pressure relief valves are safety devices specifically designed to protect a pressurized system during an overpressure event. The relief valves automatically release excess gas or liquid from a fluid system when the pressure exceeds a predetermined set point to protect the equipment and prevent damage or failure. Each pressure relief valve is designed to handle different forms of pressure and is an essential component of the pneumatic control valves to greatly benefit the pneumatic fluid control systems.

Polyconn provides many types of pressure relief valves from our extensive valve selection to add safety and quality to your pneumatic system. Contact us for more information about our relief valves or request a quote for more specific options.

Types of Relief Valves Available From Polyconn

Polyconn provides several high-quality relief valves made from top materials such as brass, stainless steel, and nylon. Our automatic air pressure relief valves are offered in various sizes and pressure tolerances, ensuring the ideal valve for any pneumatic control system. We supply both low-flow relief valves for applications where smaller amounts of airflow must be vented and high-flow relief valves for applications requiring greater airflow capacity. In addition, many of the low and high-flow relief valves are “coded” to meet an industry code or certification standard and used for regulated applications. Polyconn offers vacuum relief valves designed to protect equipment by admitting air when a vacuum condition develops.

How to Select the Right Relief Valve

The varying types, sizes, materials, and different pressure ratings offer many options to select relief valves, but which one would work best for your application? Fortunately, by determining the different needs you have, selecting the right automatic air pressure relief valve is doable.

First, match the valve pressure range to system requirements, and consider the size and port configuration for compatibility as well.
Next, choose the material and construction based on the environment and duty cycle. Some materials offer more durability, others more corrosion resistance.
Lastly, verify compliance based on safety standards in your application.
