Butterfly Valves
Space-saving resilient seated butterfly valve for water, HVAC and general industrial pipelines.
Engineered around the medium, pressure, temperature and operating duty.
Lightweight butterfly valve designed to fit between pipeline flanges. A centered disc and resilient seat provide economical on/off isolation for water and utility systems.
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
Compact face-to-face dimension reduces weight and installation space.
Centering features assist alignment between mating flanges.
Resilient seat isolates the body from the medium in compatible designs.
Available with lever, worm gear, pneumatic or electric actuation.
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.
Cast iron, ductile iron, carbon steel or stainless steel
Coated ductile iron or stainless steel disc; stainless stem
EPDM, NBR or PTFE
Wafer pattern for EN, ASME or JIS flanges
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.
