The Lee Company’s new field proven .281 in diameter pressure relief valves are made with materials specifically chosen for optimal performance in harsh duty applications, such as those in the oil tool industry. These new high speed, direct acting valves are constructed entirely of corrosion-resistant materials that are compliant with NACE specification MR0175/ISO 15156. Standard valves are available in forward and reverse flow directions with cracking pressures from 80 to 5900 psid. Custom models are also available with cracking pressures as high as 12,000 psid. Each Lee pressure relief valve is 100% tested and inspected to ensure reliable consistent performance.
