The Bray McCannalok MK Series high performance butterfly valves set the quality and design standard by which all other high performance valves are measured. The MK Series is ideally suited to high pressure, high temperature, and high cycle HVAC applications as well as mission critical HVAC applications.

Available in ANSI Class 150 ratings, both 2-way and 3-way, and ANSI Class 300 ratings in 2-way configurations, Bray’s MK Series valves are provided with a wide variety of direct mount Bray electric and pneumatic actuators and accessories. All valves are tested for bubble tight close-off to API 598 standards at maximum rated differential pressure.

Features:

• Double Offset Stem/Disc
• Blow-Out Proof Stem
• Energized RTFE Seat
• Pressure Assisted, But Not Pressure Dependent Seat Design Differential Pressures
• Dead End Rating Equal to Nominal Pressure Rating

Bray’s NY and AB series resilient seated butterfly valves set the design standard for quality, reliability and long life in a wide variety of HVAC applications. Specifically designed for automated applications on chilled water, hot water and condenser water, all AB and NY series automated butterfly valves are 100% factory tested for bubble tight shut off and low seating/unseating torque.

NY and AB Series valves are available in 2-way and 3-way configurations in sizes from 2” to 20”. Actuators include industrial electric, commercial electric, high pressure pneumatic and low pressure pneumatic in both spring return and non spring return variations for on/off and modulating control applications. Differential pressure ratings are available for high close-off (up to 175 PSI) and low close-off (50 PSI) requirements.

Features:

• High Purity Peroxide Cured EPDM Seats
• Pressure Equipment Directive (PED) Approval
• Wide Variety of Direct Mount Actuators
• Internal Disc-To-Stem Connection
• Nylon Coated Ductile Iron Disc (NY Series)
