Butterfly valves are valves which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off.

Bray Control Valves offer precision control and bubble-tight shut off combined in one valve. These valves feature fast response times to control signals due to advanced digitally controlled actuators plus the inherent strengths of butterfly valves. Other features include high flow capacity, ease of maintenance and exceptional interface with PLCs and computer command signals.

Bray’s resilient seated control butterfly valves range from 1″–24″ (25mm–600mm) and are available with a variety of body materials in both wafer, lug and flanged styles. Disc materials include Nylon 11 powder coated ductile iron, aluminum, bronze, stainless steel, or PTFE and UHMWPE molded over stainless steel discs. Pressure ratings are available from vacuum to 175 psi (12 bar) and ASME/ ANSI Class 150, 300 & 600 ratings. Non-Fire Safe valves and Fire Safe valves certified to API 607 4th Edition are offered.

  • All Bray valves are pressure tested to 110% of rated pressure to assure bubble tight shutoff.
  • Material Traceability – Certification is provided for all valves upon request for all pressure retaining components.
  • Positive Material Identification – All materials are subjected to PMI testing to verify material traceability certificate.
