Butterfly Valves Engineering Guide

Butterfly Valves

Butterfly Valves are selected for large-diameter isolation and control for water, hvac, fire protection, chemical, power and oil-and-gas services. The correct configuration depends on pressure class, temperature, media, materials, end connection and inspection requirements. Choose concentric, double-offset or triple-offset designs by seat material, temperature, leakage class, torque, pressure class and wafer, lug or flanged connection.

Typical service
Large-diameter isolation and control for water, HVAC, fire protection, chemical, power and oil-and-gas services.
Selection points
Choose concentric, double-offset or triple-offset designs by seat material, temperature, leakage class, torque, pressure class and wafer, lug or flanged connection.
Applicable standards
API 609, EN 593, ASME B16.34, ISO 5752 and API 598.

Plant application

Water & wastewater large-bore isolation

Function
Isolation or modulating duty on large-diameter water lines.
Medium family
Raw water, potable water or wastewater — lining/seat material confirmed against the water chemistry.
Pressure & temperature
Typical concentric/double-offset ratings follow API 609. Large-bore supply is limited to 56 in / DN1400 site capability; SKU size still governs.
Applicable standards
API 609, EN 593, ISO 5752 and API 598 as applicable.
Send with RFQ
DN, pressure class, wafer/lug/flanged, seat material, operation and leakage class.
Related application

Chemical / process isolation

Function
On/off or limited control where a butterfly is accepted by the piping class.
Medium family
Process chemicals and utilities. Elastomer vs metal seat follows medium and temperature.
Pressure & temperature
Temperature and tightness class confirmed on the datasheet. Do not assume fire-safe or NACE unless specified.
Applicable standards
API 609 / ASME B16.34 / API 598. Project specification controls seat and leakage.
Send with RFQ
Medium, temperature, seat/disc material, ends, operation and test documents.
Related application

High-performance / triple-offset (when specified)

Function
Higher-temperature or tighter shutoff isolation when a triple-offset design is specified.
Medium family
Steam, hydrocarbons or utilities listed on the project datasheet.
Pressure & temperature
Offset geometry, class and leakage class are SKU-specific. Fire-safe testing only when specified.
Applicable standards
API 609 Category B, ASME B16.34 and the project fire-test specification when required.
Send with RFQ
Class, size, offset type, leakage class, fire-test flag, ends and actuator torque data.
