Pressure Independent Control Valves
At Valveforce, we understand the critical role that Pressure Independent Control Valves (PICVs) play in regulating fluid flow, pressure, and temperature across a variety of industrial systems. These valves are essential in maintaining operational safety, efficiency, and stability in steam, gas, and liquid systems. Our expert services ensure that your valves are installed, maintained, and repaired to the highest standards, keeping your system running smoothly.

Pressure Independent Control Valves Explained
Pressure Independent Control Valves (PICVs) are specialised mechanical valves commonly used in hydronic (water-based) heating and cooling systems. Their primary function is to maintain a consistent, predetermined flow rate regardless of pressure variations within the system.
PICVs combine two main functions in one valve:
Automatic flow regulation:
They automatically adjust the valve's internal mechanism to maintain a constant flow rate, even if the pressure fluctuates within the pipework.
Control (actuator-driven):
They allow precise control of flow via external actuators connected to building automation systems (BAS) or thermostatic controllers. This enables accurate temperature control at each terminal unit (e.g., fan coil units, radiators, chilled beams).

Specification & Design
The performance of a pressure independent control valve depends on its design and compatibility with the system’s requirements. Proper specification ensures efficiency, reliability, and reduced energy consumption. Key considerations:
Flow & Pressure
Selecting a valve suited to the required flow rate and pressure levels.
Material Compatibility
Ensuring materials withstand the operating environment’s conditions.
Control Precision
Choosing the right actuator for precise pressure and flow control.
Safety Features
Incorporating fail-safe modes, pressure relief, and emergency shutoff.
Custom Designs
Tailored solutions for unique applications.
Installation & Commissioning
