CLA-VAL 40-111 : Differential Pressure Control Valve

CLA-VAL 40-111 : Differential Pressure Control Valve (DPCV) Cla-Val 40-111 are hydraulically operated, pilot controlled, modulating valves designed to maintain a constant differential pressure across a pipe-work sub-circuit or temperature control valve to a pre-determined value despite fluctuations in mains pressure and/or flow-rate.

PICV versus Conventional Solutions - FlowCon

The PICV is basically a DPCV, a CV and a dynamic balancing valve built into one unit. The dynamic valve acts as an overflow preventer ensuring that overflow is never present in the coil. The DPCV ensures that the differential pressure across the CV section remains constant and that flow therefore does not change with system pressure fluctuations.

What is Variable Flow? - Crane Fluid Systems

Once a sub circuit has been commissioned, Crane FS DPCV protects the flow and balance from being affected by other sub circuits; this is referred to as a semi-automatic method of balancing the system. Fully automatic balancing can be used in both variable and constant flow systems to enhance the performance of any HVAC system and save energy ...

R206CF - Differential pressure control valve DPCV, flanged

Differential pressure control valve DPCV with flanged connections. The valves balance and control the differential pressure automatically and proportionally. The valve balances the flow in the main network or in the single risers and branches of a heating/cooling system, controls and keeps the differential pressure over the load at a stable ...

Differential Pressure Control Valves | HVAC Product - Dutco

Very much efficient, the DPCV is set to a maximum differential pressure that ensures flow cannot exceed a desired rate. It, therefore, helps reduce energy consumption, the risk of noise and simplifies the commissioning process. A differential pressure control valve ensures a constant differential pressure across a Hydronics system with variable ...

Module 140: Pressure-independent control valves in variable …

The DPCV contains a diaphragm that separates two chambers in the valve; in this example, one chamber is connected (internally) to the valve inlet and the other, via a capillary tube, to a tapping in the double-regulating valve in the flow pipework. An adjustable spring-loaded valve spindle is connected to the diaphragm, closing the valve when ...
