Bray Industrial Flow Control Valves, Actuators and Control Systems

Bray Series 30 & Series 31 Resilient Seated Butterfly Valves

Bray Series 30 wafer and Series 31 lug resilient seated butterfly valves are engineered for isolation and flow regulation across water treatment, HVAC, power generation, chemical processing, and general industrial pipelines.

The design features a pinless splined stem connection, precision-machined spherical disc edge for minimal torque, and interchangeable tongue-and-groove elastomer seats in EPDM, BUNA-N, FKM, and virgin PTFE.

The valves achieve ISO 5208 Rate A bidirectional bubble-tight shutoff at pressures up to 16 bar (DN 50–300) and 10 bar (DN 350–500) across temperatures from -40°C to +204°C. Molded seat face profiles eliminate the need for separate flange gaskets during installation.

Specify nominal diameter DN (50–500 mm), body style (Wafer/Lug), disc material (316SS, Al-Bronze, Ductile Iron), seat elastomer, and actuator interface.

Bray Series 20/21 Sanitary/Chemical & Series 31H High Pressure Valves

The specialized Bray Series 20 (wafer) and Series 21 (lug) butterfly valves feature a two-piece split body architecture engineered for rapid sanitation, maintenance, and seat replacement in food, beverage, pharmaceutical, and corrosive chemical processes.

Available trims include discs encapsulated with thick PTFE, Halar, and Nylon 11 coatings or machined from Hastelloy and titanium alloys.

The high-pressure Bray Series 31H line is rated for dead-end service at differential pressures up to 17.2 bar (250 psi) in heavy slurry and high-pressure industrial pumping systems. The standardized ISO 5211 mounting flange allows direct actuator installation without intermediary mounting brackets.

Specify diameter DN (25–600 mm), differential pressure (up to 17.2 bar for 31H), disc coating (316SS polished, PTFE lined, Hastelloy), and sanitary compliance.

Bray Tri-Lok® Triple Offset & McCannalok High Performance Valves

Bray Tri-Lok triple-offset and McCannalok double-offset high-performance butterfly valves are engineered for severe process service involving superheated steam, cryogenic fluids, LNG processing, hydrocarbon refining, and geothermal heat transfer.

The Tri-Lok non-rubbing metal-to-metal seat geometry completely prevents friction wear during cycle travel, guaranteeing ISO 5208 Rate A and API 598 bi-directional zero-leakage shutoff across temperatures from -196°C to +450°C and pressure classes ASME 150 to 900 (DN 80–1200).

The McCannalok series (Series 40–45) incorporates dynamic pressure-energized RTFE and Fire-Safe resilient seating for volatile chemical duties.

Specify ASME pressure class (150, 300, 600, 900), body connection (Wafer, Lug, Double Flanged, Butt-Weld), temperature rating, and metallurgy (WCB, CF8M, Inconel, Monel).

Bray Flow-Tek Industrial Ball Valves: 3-Piece, Flanged & Multiport

The Flow-Tek valve line (a division of Bray International) comprises full-port and standard-port ball valves for isolation, emergency shutdown, and throttling control.

Series S7000 and S8000 feature three-piece swing-out body construction, allowing inline replacement of seats and seals without disturbing welded or threaded pipe connections.

Flanged two-piece Series F15 and F30 ball valves (ASME Class 150/300, DN 15–300) are fully certified to API 607 Fire-Safe testing standards.

Heavy-duty Triad Series valves handle extreme pressures up to 148 bar (2140 psi), while Multiport Series MPF/130/140 valves provide versatile 3-way and 4-way flow routing and blending.

Specify valve style (3-piece, flanged 2-piece, multiport), pressure rating, ball and seat metallurgy/trim (TFM 1600, RTFE, PEEK), and Fire-Safe requirement.

Bray Slurry & Knife Gate Valves: Series 740, 746 & 752

Bray Series 740 uni-directional and Series 746/752 bi-directional knife gate and slurry valves are engineered for severe isolation of dense mining slurries, cement slurries, paper pulp, ash handling, tailings, and bulk dry solids across mineral processing, steel mills, power generation, and paper plants.

The valves feature a precision-beveled stainless gate blade (304, 316, 254SMO, 17-4PH) capable of shearing through fibers and abrasive solids. Replaceable elastomer seat sleeves and full-port polyurethane liners isolate the ductile iron body from erosive wear.

Actuation options include heavy-duty pneumatic cylinders, hydraulic actuators, electric drives, and bevel gear handwheels.

Specify nominal size DN (50–900 mm), flow direction (uni/bi-directional), liner elastomer (Polyurethane, EPDM, Natural Rubber), blade alloy, and actuation type.

Bray Series 92/93 Pneumatic Actuators & Series 98 Scotch Yoke

Bray Series 92 double-acting and Series 93 spring-return quarter-turn pneumatic rack and pinion actuators deliver reliable automated operation for butterfly valves, ball valves, and dampers.

Housed in heavy-duty extruded anodized aluminum bodies with electrostatic polyester exterior protection, they feature die-cast aluminum opposed pistons and zinc-plated output pinion shafts conforming directly to ISO 5211 and NAMUR accessory standards.

Rated for operating air pressure up to 10 bar (140 psig) and temperatures from -20°C to +93°C (low-temp to -40°C, high-temp XT to +150°C). For large heavy valves, Series 98 pneumatic and 98H hydraulic scotch yoke actuators deliver torques exceeding 100,000 Nm.

Specify required torque output, operating mode (double acting S92 or spring return S93), air supply pressure, and temperature trim (standard, -40°C low-temp, +150°C XT).

Bray Series 70 Industrial Electric Actuators & Series 70-HAZ

Bray Series 70 industrial quarter-turn electric actuators and Series 70-HAZ explosion-proof models deliver precise positioning, on-off isolation, and modulating control for butterfly and ball valves.
