Butterfly Valves
Compact isolation valve for end-of-line and equipment service with manual, pneumatic or electric actuation.
Engineered around the medium, pressure, temperature and operating duty.
Compact quarter-turn isolation valve with threaded body lugs for secure mounting, equipment isolation and end-of-line service. Manual, pneumatic and electric operation can be matched to the duty.
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
Threaded lugs support downstream piping removal and end-of-line isolation.
Replaceable resilient seat provides tight shut-off in suitable service.
Low operating torque supports lever, gearbox and automated operation.
Body, disc and seat materials can be selected for the medium.
CONFIGURATION OPTIONS
Material combinations are reviewed against corrosion, erosion, temperature and required service life. The final approved data sheet defines every pressure-containing and wetted component.
Ductile iron, carbon steel or stainless steel
Stainless steel or coated ductile iron disc; stainless stem
EPDM, NBR or PTFE
Lugged wafer pattern
VALVE + OPERATOR
Manual and automated packages are selected using the valve operating load, maximum differential pressure, required speed and available site utilities.
Lever, handwheel or gearbox options are matched to size, torque and access.
Double-acting or spring-return packages can include solenoid, switch box and positioner.
On/off or modulating actuators are configured for voltage, duty, enclosure and control signal.
Torque or thrust, safety factor, mounting interface, travel time and fail position are checked together.
