Solutions & Product Series
FlowCon manufactures pressure-independent control valves (PICVs) and hydronic balancing products that combine differential pressure control, flow limitation, and modulating control in a single compact valve. Designed for variable-flow hydronic systems in commercial and institutional buildings, FlowCon products eliminate the need for separate balancing valves and simplify commissioning across all system loads.
FlowCon Green PICV
Pressure-independent control valve — the original single-valve solution
- Combines DP regulator, flow limiter, and control valve in one body
- Maintains set flow regardless of pressure fluctuations (±5% accuracy)
- DN15 to DN50 — available in 2-way and 3-way configurations
- Compatible with most standard actuators (2-point, floating, modulating)
- Pre-set maximum flow — eliminates hydronic balancing step
- WRAS-approved materials for domestic water applications
FlowCon SM/SMT
Compact pressure-independent valve for coil connections
- Ultra-compact body — ideal for tight fan coil and AHU connections
- Built-in strainer protects valve from system debris
- Easy flow setting with indexed setter dial
- Available in straight and angle-body configurations
- Spring-return actuator options for fail-safe operation
- Suitable for 2-pipe and 4-pipe hydronic systems
FlowCon DP Controller
Self-acting differential pressure regulator
- Maintains constant differential pressure across sub-circuits
- No external power required — fully self-acting spring mechanism
- DN15 to DN150 for main distribution and branch circuits
- Field-adjustable setpoint within rated range
- Compatible with building automation and BMS override
- Prevents noise, hunting, and starving in variable-flow distribution
FlowCon Black / Orange
High-capacity PICVs for primary plant and large AHUs
- DN65 to DN200 — designed for large air handling and chilled beams
- Optional built-in flow measurement ports (Pt-100 or pressure taps)
- High differential pressure capability — up to 400 kPa
- Flanged and grooved end connections available
- Compatible with multi-turn and quarter-turn actuators
- BACnet, Modbus, or LON-enabled actuator packages
Why Choose FlowCon
Key Advantages
Single-Valve Simplicity
FlowCon PICVs replace three separate components — a balancing valve, a differential pressure controller, and a control valve — reducing installed cost, leak points, and commissioning time.
Accurate Flow Control
±5% flow accuracy across the entire differential pressure operating range ensures each terminal unit receives exactly the design flow — in both full-load and part-load conditions.
No Commissioning Required
Pre-set flow limiters eliminate traditional balancing procedures — plug-and-play installation at every terminal reduces mechanical contractor time and commissioning cost.
Variable Flow Ready
Designed from the ground up for variable-flow primary/secondary and direct variable-flow systems — enabling pump speed reduction and energy savings at part load.
Actuator Flexibility
Works with most standard 2-point, floating, and 0–10V modulating actuators from major BMS and controls manufacturers — no proprietary hardware required.
Verified Performance
All FlowCon products are independently tested and certified to EN 215 and ANSI/ASHRAE standards — providing engineers the certified data needed for energy modeling and LEED documentation.
