Butterfly Valve Range

Start with the HF-520 aluminum butterfly valve for compatible water, HVAC and equipment projects, then compare offset, lined and ductile-iron alternatives when the service or project specification requires another construction.

Four butterfly-valve routes for different duties

Compare body and wetted materials, seat system, pressure class, connection and actuation to find the right starting point.

Selection sequence

Choose construction from the service data

Body material alone is not enough; review the complete pressure boundary and wetted-material system.

01

Medium

Name the fluid, concentration, contaminants and solids before screening seat, lining and trim.

02

Pressure & temperature

Supply normal and maximum values, differential pressure and any upset or cleaning condition.

03

Connection & size

Confirm nominal size, flange standard, pressure class, face-to-face and available installation space.

04

Operation

Define isolation or control duty, cycle frequency, fail position, utilities and required accessories.

Selection support

Start with the aluminum platform, then change construction only when the duty requires it.

Send the medium, pressure, temperature, size, flange standard, actuation and project documentation requirements for a side-by-side product-family review.
