Velan leads the way in manufacturing high-performance pressure seal valves and bolted bonnet valves for some of the world’s leading industrial companies. Velan’s pressure seal line includes multiple gate, globe, and check valve designs ideal for many high-pressure (HP) and high-temperature (HT) applications. Bolted bonnet valves offer strong, leakproof joints with a higher bolting torque to deliver a superior seal and tightness.
