Any system or vessel produces high levels of pressure, at times too much for the system to handle. However, there’s something that can ensure protection and consistent stable operation in overpressure events: high pressure relief valves.

According to Wermac.org, the spring-loaded pressure relief valve is designed with a valve inlet or nozzle mounted on the pressurized system, a disc against the nozzle to prevent flow under normal system operating conditions, and a spring to hold the disc closed. This type of valve can also be adjusted to specific pressures.

Wermac.org also mentions that a balanced bellows valve and a balanced piston valve should be used when superimposed back pressure is variable. These valves include a pressure area equal to the seat area of the disc as well as a Bonnet that’s vented to keep the pressure area exposed to atmospheric pressure. This will also provide an easier way to detect leaks in the bellows or pistons.

In the event of an overpressure situation where the pressure of the system is above the regulator’s setpoint, these valves will vent gas or liquid away from the vessel or system to a safe location. This ensures consistently safe pressure levels and prevents damage and complete system failure. Once the vessel or system has normalized, the relief valves will close until they’re needed again.

High pressure relief valves are vital to many piping systems and vessels. From electronic to pneumatic to hydraulic systems, they all need a high pressure valve to ensure protection and safety.

There are numerous types of high pressure relief valves. The most common are a spring-loaded pressure relief valve, a balanced bellows valve, and a balanced piston valve.

Safety valves tend to be used for more emergency situations. They operate similarly to high pressure valves, but they open instantly to their full capacity as soon as the system hits the set pressure of the valve.

High pressure relief valves are commonly referred to as safety valves. However, these are two different devices. A high pressure relief valve opens gradually depending on the system’s overall pressure levels. As pressure increases, the valve’s opening gets bigger to maintain stability.

The Fleck 2850 commercial valve is a 1.5 inch valve, with a 1.5 inch inlet and outlet as well as a 1.5 inch distributor pilot. Typically, the 2850 valve is used on 10 inch diameter to 36 inch diameter pressure vessels. The 2850 commercial valve has the ability to be top mounted or side mounted depending on the requirements of the application. The valve has a Cv of 13.2 GPM and can backwash up to 49 GPM. The weight of just the valve is approximately 19 pounds with a working pressure range of 20 to 125 psi. Operating temperatures range from 34 degrees to 110 degrees Fahrenheit. When the 2850 valve is used for a water softener application a 1600, 1650, or 1700 brine valve is used.

High pressure relief valves are known to be one of the most reliable types of overpressure protection and present numerous benefits as well. For example, they don’t block normal flow through a line, and they don’t negatively affect regulators.  On top of that, high pressure relief valves act as alarms during an overpressure event.
