Flexible connector for thermal expansion, vibration and pipeline movement.
Engineered around the medium, pressure, temperature and operating duty.
Product overview
Flexible metallic connector designed to absorb thermal expansion, vibration and controlled pipeline movement while maintaining pressure containment.
Greysen reviews the complete operating case before confirming the valve. Body style, wetted materials, sealing system, connection standard and operator are matched as one project configuration.

DESIGN DETAILS
Features and benefits
01
Valve construction
Bellows geometry is engineered for axial, lateral or angular movement.
02
Sealing performance
Optional liners protect convolutions from velocity or abrasive flow.
03
Reliable operation
Tie rods and restraints control pressure thrust where required.
04
Project flexibility
Design review considers cycles, temperature, pressure and installation length.

VALVE + OPERATOR
Operation and automation
Manual and automated packages are selected using the valve operating load, maximum differential pressure, required speed and available site utilities.
Manual operation
Lever, handwheel or gearbox options are matched to size, torque and access.
Pneumatic actuation
Double-acting or spring-return packages can include solenoid, switch box and positioner.
Electric actuation
On/off or modulating actuators are configured for voltage, duty, enclosure and control signal.
Package verification
Torque or thrust, safety factor, mounting interface, travel time and fail position are checked together.
