Common Questions
Frequently asked questions about butterfly valves.
Engineering and procurement questions we hear most often. For project-specific guidance, send your application details via RFQ.
When should I choose butterfly over ball valves?
Butterfly valves are preferred for larger sizes (typically 2" and up) where ball valves become heavy and expensive. They offer faster quarter-turn operation, lower torque, smaller footprint and lower cost in larger sizes.
Ball valves remain better for full-bore flow, throttling control and where complete shutoff is critical. Butterfly valves are ideal for on/off service, larger lines and where space is constrained.
What seat material is best for high-temperature service?
For continuous service above 130°C, choose silicone (up to 200°C) or Viton/FKM (up to 200°C). For SIP cycles at 121–135°C, silicone or PTFE-faced seats provide best durability.
EPDM is standard for ambient and CIP service up to 130°C. For sustained high temperature or aggressive chemicals, specify silicone, Viton or PTFE-faced seats.
Can butterfly valves throttle flow?
Yes, but with limitations. Effective control range is typically 30–70° of disc rotation. Outside this range, control authority drops and cavitation risk increases.
For dedicated control applications, request a butterfly valve with positioner and characterized disc. For simple throttling, manual valves with multi-position handles are available.
What is the difference between wafer, lug and double-flanged?
Wafer style fits between two pipe flanges using long bolts. Lug style has threaded inserts allowing one pipe to be removed without affecting the valve. Double-flanged has integrated flanges.
For sanitary service, tri-clamp connections are most common and avoid flange complications entirely. Specify connection style based on pipe spec.
How much torque is needed for manual operation?
Manual lever operation is suitable up to DN100 (4"). Above this size, gearbox or pneumatic actuator is recommended due to high break-away torque.
Actual torque depends on size, seat material, differential pressure and media. Provide line conditions when specifying for actuator sizing.
What documentation is available?
Standard documentation includes EN 10204 3.1 MTR for body and disc materials. Optional packages include FDA compliance for seats, ASME BPE surface finish reports, ATEX certificates.
For pharmaceutical applications, specify ASME BPE compliance and request full traceability package.
Are pneumatic actuators ATEX-rated?
Standard actuators are not ATEX-certified. For hazardous area service, specify ATEX-rated solenoid valves, limit switches and proximity sensors with the actuator package.
Provide zone classification (Zone 1, Zone 2) and gas/dust group with your RFQ. Full ATEX-rated assemblies available.
Need sanitary butterfly valves for a project or plant replacement?
Send size, connection, seat material, actuator type, quantity, service conditions and documentation requirements for a structured technical RFQ.
