The Bray Simple Set Max is a flanged pressure independent control (PIC) valve designed for a wide variety of hot water and chilled water control applications. The SSM Series combines high rangeability control with dynamic balancing into a single compact housing, eliminating material installation and commissioning costs of separate balancing components.
The maximum flow rate is easily set by hand with an adjustment on the top of the valve. The unique design of the Simple Set Max provides full stroke of the control element, even when the flow rate setting is a small percentage of the maximum flow capacity of the valve.
Simple Set Max valves provide a continuous flow rate at any fixed position of the valve irrespective of inlet pressure change. This prevents overflow at any load condition, which contributes to optimal coil performance and primary equipment efficiency.
The Bray GA(S) Series is a direct mount line of linear motor actuators to be used primarily on PIC and globe valves. The patented drive-valve coupling allows the drive to be connected to the valve automatically as soon as the power is applied to the actuator. An external crank handle enables the desired position to be set manually as well. Microprocessor technology enables the actuator to identify the functions required and to adapt itself automatically to the control valve properties.
These actuators operate on 24V AC or DC, and all input signals- 0-10V or 4-20mA modulating output, or On/Off (2-point) or Floating (3-point) control. The actuator automatically detects the control signal applied via a 2 LED display. These actuators operate both 2 and 3-way valves and are available in non-spring return (GA) and spring return (GAS) versions.
The GA(S) series is bi-directional, selectable via screw terminals.

"I ordered a part to be shipped to Arkansas. NorthStock had the best price that I could find. They shipped the part fast and it (fan motor) runs quieter than when new."
