Frequently Asked Questions
Find quick answers to some of the most common questions
What is a pressure independent control valve (PICV)?
A pressure independent control valve is a control valve that maintains stable, design‑accurate flow regardless of system pressure fluctuations. It combines control, flow regulation, and pressure compensation into one device, eliminating the need for balancing valves and ensuring coils receive the correct flow at all load conditions.
What is the DeltaPValve® and how does it differ from traditional control valves?
The DeltaPValve is Flow Control’s flagship PICV, originally developed in 1988 as the first PICV designed specifically for HVAC hydronic systems. Unlike traditional control valves, the DeltaPValve provides true pressure independence, self-balancing operation, and precision flow control across the entire hydronic system. Each valve is hand‑built and individually tested at FCI’s Washington facility to ensure consistent performance.
What maintenance is required for DeltaPValves?
DeltaPValves require very little maintenance because they are built with an industrial‑quality, debris‑resistant design. Routine maintenance consists of two simple tasks:
- Verify pressure‑independent operation using the valve’s integral P/T ports.
- Perform a visual inspection to check for leaks or any physical damage to the valve or piping.
No flow balancing, recalibration, or seasonal recommissioning is ever required. The valve’s self-balancing design maintains correct flow for its entire service life, eliminating the ongoing hydronic adjustments typically needed with conventional control valves.
Are DeltaPValves truly self‑balancing, and what does that mean for system operation?
Yes. DeltaPValves are fully self‑balancing by design. Because each valve integrates control, flow regulation, and pressure compensation into a single device, it automatically maintains the correct design flow regardless of system pressure fluctuations. This eliminates the need for manual balancing valves, seasonal recommissioning, or ongoing hydronic adjustments.
Once installed, the valve continuously delivers the required flow at all load conditions, ensuring coils receive stable, design‑accurate water without technician intervention. This self‑balancing behavior is a core advantage of the DeltaPValve and a major reason it performs consistently across the entire hydronic system.
