Operation

Uni-LOK "RVL1" Series Relief Valves are designed for upsteam pressure overcomes the force exerted by the spring, the poppet opens, allowing flow throuth the valve.
As the upstream pressure increases, flow through the valve increases proportinately.
Creaking pressure is only sensitive to inlet pressureand is not affected by outlet pressure.
To increase the cracking pressure of the valve, the spring must be compressed by simply turing the adjustment cap clockwise.

General Information

Maximum Working Pressure 300 psing (21kg/㎠)
Cracking Pressures from 30 psig to 220 psig(2.1kg/㎠ to15.5kg/㎠) to atmosphere.
Maximum Outlet Pressure 300 psig (21kg/㎠) should not exceed inlet pressure.
Operating Temperature Range -23℃ to 200℃ (-10°F to 392°F)
Material : 316 Stainless Steel Construction.
