Gresswell Valves FIG134 and FIG134EL General Purpose Pressure Relief Valves
A range of relief valves, the Gresswell FIG134 is used frequently for preventing safe pressures being exceeded in pressurised systems.
The valve lift is proportional to the system over pressure. The FIG134 is commonly used for air, oil, gases and steam, where high discharge rates are not desirable in thermal and pipeline relief applications.
Size Range:
 DN15 TO DN100 (½" TO 4")
Pressure Range:
DN15 (½") - DN25 (1") = 0.7 bar.g (10 psi) to 22.5 bar.g (326 psi)
DN32 (1 ¼") - DN50 (2") = 0.7 bar.g (10 psi) to 20 bar.g (290 psi)
DN65 (2 ½") - DN100 (4") = 1.0 bar.g (15 psi) to 15 bar.g (218 psi)
