The Claval Plug Valve is a quarter-turn rotary isolation valve engineered for dependable on/off service across upstream, midstream and downstream oil and gas applications. Its sleeve-type soft sealing design delivers consistent zero-leakage shut-off in both flow directions, while the unique 360° metal lip protection around the sleeve ensures long-term sealing integrity — even in viscous, fouling or corrosive process conditions. Available in lubricated and non-lubricated configurations across a wide range of materials and pressure classes.

Benefits

• 360° metal lip protection on the sleeve sealing surface provides a self-cleaning action during rotation — ideal for viscous, sticky or easily fouling media
• No body cavity to accumulate process media, eliminating the risk of trapped pressure build-up and simplifying maintenance
• Bi-directional tight shut-off allows flexible installation without consideration of flow direction
• Wide material selection — from carbon steel to exotic alloys — ensures compatibility across the full range of oil and gas process conditions
• Fire-safe certified construction for safe, reliable operation in hydrocarbon and high-hazard service
