At Kriloha Ltd., we supply Check Valve Unions, compact safety devices that combine a union connection with a one-way check valve. These prevent backflow of well fluids into wireline equipment, improving safety during pressure control operations. Manufactured from high-strength alloy steels with precision-machined sealing surfaces, Kriloha check valve unions are designed for high-pressure and high-temperature wells. Applications include wireline interventions, lubricator safety systems, blowout prevention, and general well control systems. Each unit undergoes hydrostatic testing, sealing integrity verification, and functional flow testing, ensuring compliance with API standards. As a supplier and facilitator, Kriloha Ltd. provides various sizes, connection options, and spare kits, making our check valve unions a reliable safety solution for well intervention operators worldwide.
