CPV Valves: Leading Choices for the Industrial Gas Industry

FloMaster® Line

The CPV FloMaster® full line features fail-safe air actuators that eliminate the need for manual valve operation, ensuring consistent, accurate and automated gas filling, even in extreme conditions. These air-operated valves, equipped with O-Seal® technology, deliver leak-proof, easy-to-maintain performance at pressures up to 6,000 psi (414 bar) and temperatures ranging from −20°F (−30°C) to 225°F (110°C).

They boast actuation pressure thresholds below 100 psi (7 bar), substantial port sizes for full flow, and a robust soft-seat design, guaranteeing bubble-tight shutoff operation over thousands of lifecycles. With positive shutoff technology and seamless integration into OEM software, FloMaster® actuators enable precise, real-time flow throttling adjustments, providing accuracies up to +/− 0.1% in system design for gas mixing and filling.

Control and Check Valves

CPV control valves ensure precise gas flow regulation, managing key factors like pressure, temperature, and gas levels during filling. Designed in various sizes and configurations, they’re essential for peak system performance in gas filling applications.

CPV check valves offer water, oil and gas (WOG) compatibility for versatile, reliable performance. With high-quality helical springs and soft-seated design, they ensure positive closure and a tight shut-off. These valves can be easily installed in any position, come in various sizes and materials, meeting your specific application needs with ease.

Oxygen Valve Quality Hinges on Compatibility and Cleanliness

Any compressed gas poses a potential risk of ignition and corresponding hazards. Oxygen for example, does not burn by itself. However, it supports combustion and, if not properly contained and managed, oxygen can react explosively or cause spontaneous ignition of other materials. This risk increases as oxygen is put under pressure and as temperatures rise.   […]
