nnnnThe Lee Company's new field proven .281 inch
nnnndiameter Pressure Relief Valves are made with
nnnnmaterials specifically chosen for optimal perfor-
nnnnmance in harsh duty applications, such as those
nnnnin the oil tool industry. These new high speed,
nnnndirect acting valves are constructed entirely of
nnnncorrosion-resistant materials that are compliant
nnnnwith NACE specification MR0175/ISO 15156.
nnnnStandard valves are available in forward and
nnnnreverse flow directions with cracking pressures
nnnnfrom 80 to 5900 psid. Custom models are also
nnnnavailable with cracking pressures as high as
nnnn12,000 psid. Each Lee pressure relief valve is
nnnn100% tested and inspected to ensure reliable
nnnnconsistent performance. Contact your local Lee
