A pressure relief valve is a crucial safety device whose primary purpose is to protect piping and other equipment from excessive pressure. Every system has recommended pressure and any higher levels could cause damage.
At A-1 Total Service Plumbing, we offer two types of pressure relief valves which are suitable for different systems.
- Spring-loaded pressure relief valves
- Pilot-operated pressure relief valves
The spring loaded valve is the basic structure that provides protection from excessive pressure. The valve contains a nozzle, a disc, and an adjustable spring load that helps the valve to open and close. An increase in pressure level increases the spring force. This causes the pressure relief valve to lift. Most of our systems are designed with overpressure allowance to ensure the valve reaches full lift.
The pilot-operated valve consists of a valve inlet and a dome area. The closing force is often greater than the opening force to ensure the main valve is tightly closed. The pilot valve has two designs. The opening can either be rapid and complete or gradual and partial. Pilot valves are often used in large low-pressure tanks.
Other functions of pressure relief valves include:
- Prevent the loss of material
- Safe removal of excess fluid
- Regulate pressure in specific sections
- Sequence motion
Causes of Excess Pressure
Different systems have different pressure limits but the reasons for overpressure are similar. It is important to consult our technicians regarding the most suitable relief valve based on your existing structural needs. Blocked outlets are also common reasons for excess pressure. External fire causes abnormal heat that alters chemical reactions. This also leads to excess pressure.
