What are PICV Valves?
Pressure Independent Control Valves (PICV or PIC valves) are essential components in modern HVAC systems. PICV valves are designed to maintain a constant flow rate regardless of pressure fluctuations in the system. By doing so, they ensure optimal performance and energy efficiency, making them a popular choice for both hot water and chilled water applications.
Pressure Independent Control Valves (PICV) offer significant advantages over traditional Pressure Dependent Valves. One of the primary benefits is their ability to maintain a constant flow rate regardless of pressure fluctuations in the system. This ensures optimal performance and energy efficiency, as the system does not need to compensate for varying pressures. In contrast, Pressure Dependent Valves require constant manual adjustments to maintain the desired flow rate, leading to inefficiencies and increased operational costs. Additionally, PICVs simplify system design and installation by eliminating the need for separate balancing valves, reducing material and labor costs. Overall, PICVs provide more reliable and efficient control, making them a superior choice for modern HVAC systems.
Why Choose Bray Commercial PICV Valves?
Bray Commercial offers two outstanding series of PICV valves: the SS Series and the SSM Series. Both series are engineered to provide superior control, reliability, and efficiency in a wide range of applications.
Bray Commercial SS Series
The Simple Set Series (SS) from Bray Commercial features threaded PIC valves ranging from 1/2″ to 2″. These valves are designed for a diverse range of hot water and chilled water control applications. Key benefits of the SS Series include:
- High Flow Rates with Minimal Pressure Drops: The SS Series valves provide high flow rates while requiring minimal pressure drops, ensuring efficient operation.
- Dynamic Balancing and High-Rangeability Control: These valves combine dynamic balancing with high-rangeability control in a single compact housing, eliminating the need for separate balancing components and reducing material, installation, and commissioning costs.
- Easy Adjustment: The maximum flow rate can be easily adjusted by hand using the adjustment located on the top of the valve, making it simple to achieve optimal flow control.
- Efficiency and Performance: Designed to deliver control and reliability, the SS Series ensures optimal performance in a wide range of applications, enhancing the efficiency of HVAC systems1.
Bray Commercial SSM Series
The Simple Set Max (SSM) Series from Bray Commercial features flanged PIC valves designed for a variety of hot water and chilled water control applications. Key benefits of the SSM Series include:
- High Rangeability Control and Dynamic Balancing: Like the SS Series, the SSM Series combines high rangeability control with dynamic balancing in a single compact housing, reducing material, installation, and commissioning costs.
- Full Stroke Control Element: The unique design of the SSM Series 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.
- Continuous Flow Rate: The SSM Series valves provide a continuous flow rate at any fixed position of the valve, irrespective of inlet pressure changes. This prevents overflow at any load condition, contributing to optimal coil performance and primary equipment efficiency2.
Conclusion
Bray Commercial’s SS Series and SSM Series PICV valves are excellent choices for anyone looking to enhance the efficiency and performance of their HVAC systems. With features like high flow rates, dynamic balancing, easy adjustment, and continuous flow rate, these valves provide reliable and efficient control for a wide range of applications. Trust Bray Commercial for innovative solutions that streamline installation, reduce costs, and ensure optimal performance.
