Differential Pressure Control Valves (DPCV)
FloControl offers exclusively the wide range of threaded and flanged FlowCon Differential Pressure Control Valves in the UK, including Partner Valves, to provide a constant differential pressure across branches. FlowCon’s DPCV range includes three different types:
- The pre-set ΔpC (differential pressure across the circuit) and tamper-proof Simple Differential Pressure Control Valve (SDP).
- The adjustable ΔpC Differential Pressure Control Valve (EDP ½”-2” and PIM 65mm-150mm).
- The combined dynamic balancing valve and adjustable DPCV (ADP).
FlowCon Differential Pressure Control Valves (DPCV), available in threaded and flanged options, maintain a constant pressure differential across a sub-branch.
Differential Pressure Control Valves (DPCV)
Differential Pressure Control Valves are critical elements in the infrastructure of hydronic heating and cooling systems. FlowCon Differential Pressure Control Valves (DPCV), available in threaded and flanged options, maintain a constant pressure differential across a sub-branch. Whether in new builds or retrofit projects, the Valves ensure performance, comfort, and longevity across the entire hydronic circuit.
The Operation of the Valves
In hydronic heating and cooling systems, the importance of maintaining a constant pressure differential cannot be overstated. System demand fluctuates due to factors such as varying occupancy levels and weather conditions. As a result, the pressure within the pipework also changes. These fluctuations can lead to instability, inefficiency, and premature system failure.
DPCV is designed to control the pressure differential—the difference in pressure between the supply and return lines. Simply put, the valves maintain a constant pressure differential across sub-branches or terminal units, regardless of what’s happening elsewhere in the network. The maintenance of a stable pressure differential offers many benefits, including:
- Stable indoor temperatures for occupants’ comfort
- Enhanced energy efficiency
- Reduces strain on the hydronic system’s components
- A smooth system operation for a peaceful indoor environment
Valve Types: Threaded and Flanged DPCV Valves
Threaded DPCVs feature screw-type end connections that make them ideal for low-to-medium pressure systems with smaller diameter pipework. Just like PICV Valves, these valves are typically compact, which facilitates easy integration into confined spaces. They are well-suited to projects where installation speed and flexibility are essential.
Flanged DPCVs are designed for use in more demanding environments where system pressures and flow volumes are significantly higher. Due to their robust construction, flanged Differential Pressure Control Valves are most often installed in large-scale commercial or industrial HVAC systems. These include chilled water circuits, heating loops, and district energy networks.

Frequently Asked Questions
What is the expected lifespan of your valves?
Our DPCV Valves are built with longevity in mind. The durable internal components and corrosion-resistant materials ensure dependable performance with minimal deterioration, even in demanding environments. Under normal DPCV Valve Function and routine system upkeep, these valves provide 10+ years of service.
What are the key benefits of using DPCV Valves in an HVAC system?
A DPCV Valve delivers multiple operational and economic advantages. It maintains stable flow conditions by automatically adjusting to changes in system demand, ensuring that each terminal unit receives the correct volume of water. As a result, there is efficient pump operation and a long-term reduction in maintenance costs.
How do I determine the correct valve size and type for my application?
To properly size a DPCV, you’ll need to evaluate several system-specific factors, including required flow rate, expected pressure differential, system complexity, and the physical space available. Our technical support team is available to assist with valve selection, ensuring the optimal match for your project’s requirements.
Can a DPCV improve energy efficiency?
Absolutely. Proper DPCV Valve selection and installation ensure energy efficiency across the HVAC system. The consistent fluid flow allows variable speed pumps to operate more efficiently and reduces the over-delivery of flow to certain areas. This eliminates unnecessary energy usage and reduces the need for excessive throttling via control valves, leading to a reduction in operational costs.
Are your DPCVs compatible with all HVAC and industrial systems?
Yes, the valves are available in a wide range of sizes, flow capacities, and connection formats, making them compatible with virtually all types of HVAC. Regardless of the nature of your project, you’ll find a bespoke design of DPCV Valve here.
How often should a DPCV be maintained or replaced?
The valves offer hassle-free maintenance, making them a popular option for both commercial and residential spaces. A visual inspection every 2 to 3 years is advisable or inline with the specific maintenance regime of the project, to ensure there is no blockage, corrosion, or external damage. The valves typically remain operational for 10+ years, depending on system conditions, water quality, and operational demands.
What are the common signs of a malfunctioning valve?
Just like a Constant Flow Valve, several symptoms can show that this valve is no longer performing optimally. The top signs of malfunction include unusual noise when in operation, inconsistent heating or cooling across zones, and pressure fluctuations.
How difficult is DPCV Valve Installation?
DPCV Valve Installation is a straightforward and time-saving process. The valves come with clear identification of flow direction, adjustable setpoints, and often include built-in test points for quick commissioning. With the help of our installation manuals and support documentation, trained technicians can set up these valves quickly.
