Pressure Relief Valve

Pressure Relief Valve

A Pressure Relief Valve (PRV) is an important safety component used to protect pressurised equipment and pipeline systems from potentially damaging overpressure conditions.

Under normal operating conditions, the valve remains closed. When the system pressure reaches the valve’s predetermined set pressure, the internal mechanism opens and allows excess pressure or media to discharge. As system pressure returns to an acceptable level, the valve reseats.

The pictured model features a compact spring-loaded design with threaded connections, making it suitable for applications where dependable automatic pressure protection is required within a relatively compact installation.

Correct selection of the valve is essential and should take into account the media, required relieving capacity, operating temperature, set pressure and system conditions.
