Cutting-Edge Technology for Superior Performance
AMEXSA's Pressure Independent Control Valves (PICVs) leverage advanced technology to achieve precise control over environmental comfort, particularly in variable capacity heating and cooling systems. Tested to meet BSRIA standards, these PICVs ensure linear performance and are constructed with high-quality materials for optimal valve performance. The PICVs offer a range of actuator options, measurement points, and a broad spectrum of pressure and flow rates, providing flexibility to cater to the diverse needs of different clients.
Enhanced Energy Efficiency and Cost Savings
Equipped with an integrated pressure regulator, AMEXSA's PICVs eliminate the issue of over-pumping, leading to significant energy savings. The valves maintain system performance across varying loads by preserving the required temperature difference (Delta T), preventing the unnecessary activation of additional chillers. This efficient system operation not only reduces equipment requirements but also leads to energy and cost savings throughout its lifecycle by minimizing performance gaps.
Commitment to Customer Service and Reliability
By choosing AMEXSA's PICVs, you can expect a service that includes prompt sales and after-sales feedback within 24 hours, integrity, professionalism, and accountability. The company has its own R&D team and strictly adheres to the ISO 9001 quality control system, ensuring high standards and reliability of its products. With over a decade of experience in the international market and a presence in more than 50 countries, AMEXSA's products have been utilized in prestigious projects such as Shangri-La hotels, IKEA, the Milan Expo, GE and Fiat workshops, and COSCO vessels, attesting to their exceptional quality and service.
* Flow Rate versus Differential Pressure
A Pressure Independent Control Valve (PICV) is a type of valve that automatically adjusts its position to maintain a consistent flow rate, regardless of changes in pressure or temperature in a hydronic system.
The PICV achieves this by combining a control valve, a differential pressure regulator, and a flow measurement device.When the PICV is installed in a hydronic system, it measures the flow rate and compares it to the desired setpoint. If the flow rate deviates from the setpoint due to changes in pressure or temperature, the PICV adjusts the position of its control valve to maintain the desired flow rate.
In summary, a PICV works by automatically adjusting its control valve to maintain a consistent flow rate in hydronic systems, regardless of changes in pressure or temperature.
Precision Flow Regulation in Hydronic Systems
The Intelligent PICV Solution
The PICV achieves this by combining a control valve, a differential pressure regulator, and a flow measurement device.When the PICV is installed in a hydronic system, it measures the flow rate and compares it to the desired setpoint. If the flow rate deviates from the setpoint due to changes in pressure or temperature, the PICV adjusts the position of its control valve to maintain the desired flow rate.
In summary, a PICV works by automatically adjusting its control valve to maintain a consistent flow rate in hydronic systems, regardless of changes in pressure or temperature.
A Pressure Independent Control Valve (PICV) is a type of valve that automatically adjusts its position to maintain a consistent flow rate, regardless of changes in pressure or temperature in a hydronic system.
PICV combine three functions:
● an presetting adjusting mechanism, with a dial for a presettable maximum volumetric flow
● a differential pressure controller, ensuring a constant differential pressure across control valves regardless of changes in pump speed or valve closures elsewhere in the system
● a modulating control valve, for controlling the volumetric flow across the valve’s path, it can be used to equipped actuators.
The mechanical series-connected differential pressure controller keeps the differential pressure (p1 – p2) constant across the control valve and thus the set volumetric flow too. The desired maximum volumetric flow can be preset with the adjusting mechanism. The volumetric flow through the control valve opening to control. The controller (not shown) and the actuator regulate the volumetric flow and consequently the desired temperature in buildings, rooms or zones.
