Bray’s MK Series High Performance Butterfly Valves are available in ANSI Class 150 and 300. Bray's high performance butterfly series is used in Building Automation, Temperature Controls, HVAC 2-Way and 3-Way Assemblies, Chilled Water, Hot Water, Steam, and Special Applications. 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 closeoff to API 598 standards at maximum rated differential pressure. 

Bray Series 70 industrial actuators have become the industry standard in the Commercial HVAC industry due to it’s compact, reliable design that mounts directly to Bray’s industry leading butterfly and industrial ball valves without the need for brackets and linkages. Available in torque outputs from 600 to 18,000 lb.-in. (68 to 2033 NM), 24V and 120VAC, On/Off and Modulating units all in NEMA 4x and IP65 rated housings. These actuators are ideal for use on valves for Chillers, Cooling Towers, Boilers, Heat Exchangers and other outdoor applications. Furthermore, its advanced electronics assure reliable compatibility with virtually any analog control signal used in today’s building automation and temperature control system.

The Series 70 Servo NXT provides precise modulating control of valve position:
- Single Finger Technology (SFT) menu driven, pushbutton, programming with LED confirmation of all settings.
- Optical isolation of all inputs/outputs.
- Input Control - 4-20 mA or 0-10 VDC or 0-5 VDC or 2-10 VD.
- Position Feedback - 4-20 mA or 0-10 VDC or 0-5 VDC.
- Auto Calibrating.
- Fail Position.
- Speed Control.
- Manual Mode.
- On board signal generator to simplify field set up.
- Fault display simplifies troubleshooting.
- Stall detection- Eliminates mechanical damage in case of obstruction or bad switch settings.
- Provides interoperability with all controllers.
