Unexpected pressure increases can put pipelines, boilers, pressure vessels, and connected equipment at risk if they are not relieved in time. A safety valve manufacturer in USA provides an automatic way to release excess pressure before it reaches an unsafe level. Once the system pressure drops back to an acceptable range, the valve closes again and restores normal operation.

Unlike a normal isolation or control valve, a safety valve remains closed during normal operation and is required to respond when a predetermined set pressure is reached. For steam and compressible-fluid applications, spring-loaded designs typically open rapidly to provide the required relieving capacity.

What Determines Safety Valve Performance?

Set Pressure

The predetermined pressure at which the safety valve begins to open and relieve excess pressure .

Overpressure

The pressure increase above set pressure enables the valve to achieve its specified relieving capacity.

Blowdown

The difference between the opening pressure and the pressure at which the valve closes and reseats.

Backpressure

Pressure at the valve outlet can influence opening, capacity and reseating depending on the valve design.
