Vent Valves
Designed for rapid depressurization and emergency blow-down, CenturyVal vent valves deliver tight shut-off (ANSI/FCI Class V/VI) when closed and high-capacity relief when opened. Whether venting high-pressure feed air, inert gases, or flammable hydrogen to atmosphere or flare, our trims are optimized for low-noise discharge and resistance to thermal shock—critical for ASU and CNG/H₂ filling applications.

Bypass / Recycle Valves
Our bypass valves function as the compressor’s first line of defense against surge and stall. With fast-stroking pneumatic or electro-hydraulic actuators and anti-cavitation multi-stage cage trims, they modulate seamlessly across full pressure differentials, recycling discharge gas back to suction without seat erosion or excessive temperature rise. This makes them ideal for the rapid load-cycling inherent in charge/discharge operations and multi-stage inter-stage recycle loops.
