The Bray Simple Set is a threaded pressure independent control (PIC) valve designed for a wide variety of hot water and chilled water control applications. The SS Series combines high rangeability control and dynamic balancing into a single compact housing, eliminating the material, installation and commissioning costs of a separate balancing component. Simple Set Pressure Independent Control Valves Way / - 0/6/8 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 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 valves achieve 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. System Types: Fan Coils, VAV Reheat Coils, Chilled Beams, Computer Room Air Conditioning Units and Air Handling Units. Features and Benefits Brass Housing with high flow cavity Robust design, resistant to high temperatures and moderate levels of particulate. Low pressure drop Reduces pump head requirements for added energy efficiency. Long Stroke Provides greater controlability. minimum straight pipe lengths required before or after the valve Provides for maximum piping flexibility, even in crowded mechanical rooms. SS-

Function Simple Set - How it Works Unlike conventional control valve sizing where valves are sized to a Cv, the Simple Set valves are simply sized for flow and pipe size. Refer to the ordering table for the wide range of flow values available. IMPORTANT: Valve diameter should NEVER exceed pipe diameter! Design The design of Simple Set combines high performance with small size and compact construction. The main components of the valve are: 5 Actuator Reacts to building controller call for more or less flow. 0 5.5 m m Pre-Setting Scale (Detail) Pre-Setting Scale Sets maximum flow allowed through the valve. Modulating Control Component. Rotates laterally to limit max flow through the valve per the Pre-Setting Scale. Moves vertically in response to the actuator call for more or less flow. Pressure Control Cartridge Ensures constant flow rate is achieved under fluctuating system pressures. As the system differential pressure increases and decreases, the Dp controller absorbs and releases pressure through an internal capillary tube maintaining a constant Dp across the valve. P/T Plugs Allows for measurement of water flow and temperature. SS-6
