PIQCV
The PIQCV (DN15-20) is a pressure-independent characterised control valve which permanently supplies all terminal units in heating and cooling applications with precisely the amount of water needed. It combines the functionality of a control valve and a differential pressure regulating valve, creating ONE precise valve which is unaffected by pressure variations in a system.
PICCV
The PICCV (DN15-50) is also a combination of a mechanically operated pressure-independent balancing valve and a Control Ball Valve. It maintains the required flow irrespectively of pressure variation in the system and thus precisely controls the flow in heating and cooling applications. It can be operated by a variety of actuators.

EPIV
The EPIV is a 2-way valve which is unaffected by pressure variations in a system. The EPIV directly measures flow by combining a magnetic flow meter and a 2-way control valve. The actuator has a powerful algorithm that modulates the control valve to maintain the flow setpoint set by the controller. The flow reading is reported back to the controller using a standard signal, and this value can be used by the Building Automation System to perform advanced control and energy strategies. The EPIV is a valve designed specifically for HVAC applications.
Belimo Energy Valve™
Know where the energy is going. Five functions in one valve – including energy monitoring. Measuring, controlling, balancing and shutting with a single valve – and it doesn’t stop there: As its fifth function, the new Belimo Energy Valve™ now also shows you where energy is being consumed. This means this characterised control valve with electronic flow setting offers you all the fundamentals required for optimising the consumption of your systems, for improved energy efficiency and for lowering operating costs.
