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.

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 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.

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.

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.

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.

The primary purpose of a safety valve is to protect life, property and the environment. Safety valves are designed to open and release excess pressure from vessels or equipment and then close again.

The function of safety valves differs depending on the load or main type of the valve. The main types of safety valves are spring-loaded, weight-loaded and controlled safety valves.

Regardless of the type or load, safety valves are set to a specific set pressure at which the medium is discharged in a controlled manner, thus preventing overpressure of the equipment. In dependence of several parameters such as the contained medium, the set pressure is individual for each safety application.

Emergency situations are not the only times relief valves are active; once installed they continuously regulate the flow of substance. They can also be pre-set to open when the pressure or temperature gets to a certain point that may be dangerous. Generally valves are placed on or near the pump head of the hose, pipe or tube. A wide variety of relief valve designs exist, although most resemble ball-check valves, swing check valves or diaphragm valves.

This last is particularly useful when controlling a flow of fluids that contains suspended solids. Most relief valves are spring operated, as are the majority of check valves. One specialized type of relief valve is known as a vacuum relief valve. As opposed to a normal relief valve, which relieves high pressure, a vacuum relief valve is used to relieve dangerously low pressures, or vacuums, by inserting air or an inert gas.

Like every other type of check valve, relief valves may be constructed from a variety of materials, including PVC, brass, ductile iron, copper, polyethylene, polypropylene, aluminum, steel, stainless steel and rubber. Which raw substance is used to produce each relief valve depends on the environment said relief valve will be in. The wrong product could result in erosion or contamination of the process stream. However, as long as research is done, finding the appropriate type of relief valve is possible. Every plumbing or fluid transfer application in the industrial, commercial and domestic arenas employ or will employ check valves. In fact, check valves of all kinds are an essential part of every day life. Because they need not be supervised to function and prevent product malfunction, check valves are not only desirable but often required by law to ensure the safety of water, gas and pressure applications.

Use these valves for emergency relief where pressures must be relieved quickly to reduce damage that could result from overpressure in a system. Where the overpressure needs to be controlled more gradually ,such as in back pressure or pump bypass applications use ourBack-pressure/Bypass valves which will reduce the probability of pressure spikes that often occur when relief valves are selected for pressure control applications. Standard metal seated valves meet ANSI/FCI Class IV seat leakage standards (0.01% of rated valve capacity, not bubble tight).

Although the valve is typically installed in the position illustrated, it can operate in any position or orientation, vertical horizontal, etc as long as it can be easily accessed for making adjustments.

Safety relief valve should only be used selectively where the materials chosen are compatible with the fluid used and will not cause corrosive buildup, crystallization or solidification in the close clearances between the piston and body bore, which could keep the poppet from opening freely. Use only clean, strained (#20 mesh min), or filtered liquids or gases so that the valve can operate without buildup of debris or solid matter which can cause the valve to malfunction. A basket strainer or high-pressure filter with the appropriate material and pressure rating can be purchased from Stra-Val.

Avoid locating the valve where freezing can occur, and if unavoidable, take precautions to insulate or heat wrap valve and piping to keep from freezing.

These valves do not carry the Canadian CRN or ASME approval stamp and should not be applied where this requirement must be met. However, the valves generally meet or exceed ASME design criteria with wall thicknesses that are much heavier than the minimums required. For an additional charge, valves can be ordered with material certs and with a certified hydro-test certificate and other tests to meet special documentation and acceptance requirements.
