VDFPR-CAGE | Pneumatic cryogenic control valve

The VDFPR-CAGE pneumatic valves are globe control valves with pneumatic actuator air OPEN (normally CLOSED) or air CLOSE (normally OPEN.) They are suitable for use with cryogenic fluids up to -196°C with the extended bonnet and stem with bellows seal. The body is globe straight pattern flow hydraulically designed to obtain a high flow coefficient CV with low pressure drop, the "CAGE" plug is especially designed for cryogenic fluids at low temperature and also allows the use of balancing plug at high differential pressures. The actuator is of pneumatic diaphragm type with supply up to 6 barg. The valves VDFPR-CAGE are manufactured according to ASME B16.34 and comply with the 97/23/EC (PED) standards requirements.
