Why Choose the CVS-288?

Ultimate Pressure Containment: Features a massive, heavy-duty body design, often forged, to withstand extreme system pressures and pipeline stresses, ensuring maximum integrity and safety. Durable, Zero-Leakage Performance: Utilizes a proven triple-offset, metal-to-metal seating design that provides bi-directional, bubble-tight shut-off without friction during seating and unseating, guaranteeing a long, maintenance-free service life. Engineered for Extreme Duty: Every component, from the anti-blowout stem to the high-strength bearings, is designed for the most demanding services, making it the ultimate choice for applications where valve failure is not an option.
