Relief valve opens when system pressure exceeds the set pressure, allowing the medium to flow out and closes when the system pressure decreases to the resealing pressure so as to protect the system.

Features: 

• 316 stainless steel structure

• Multiple springs for a selection of set pressure ranges

• 1/8 and 1/2 in. and 3 to 12mm end connections

• Set pressure from 1000psi to 3000psi

• The set pressure is the upstream pressure at which the first indication of flow occurs.

• The repeatability of set pressure of each valve after initial relief is ±5% at room temperature.
