AVENTICS Pressure Regulator Working Principle:

AVENTICS Pressure Regulating Valve Working Principle:

By receiving signals from industrial automation control systems (e.g., 4~20mA), the valve is driven to change the cross-sectional area between the valve core and seat, controlling the flow rate, temperature, pressure, and other process parameters of the pipeline medium. This achieves automated regulation.

AVENTICS Pressure Regulator Features:

A small-flow regulating valve, as the name suggests, is a regulating valve with a very small flow capacity.

The flow capacity of a valve is a valve capacity indicator under uniform conditions. In my country, it is expressed using the C value. The flow rate is defined as the volume of medium flowing through the valve per hour (m³/h) when the valve is fully open, with a pressure difference of 1 kg/cm² and a media density of 1 g/cm³. For incompressible fluids, the flow capacity of a valve under fully turbulent conditions depends solely on the valve's structure. When calculating the required valve flow capacity, it is important to note that the flow state within the valve can vary significantly depending on the medium or flow conditions.

In low-flow conditions, especially with viscous fluids and under low pressure, the primary constraint of the fluid is often laminar flow or a mixture of laminar and turbulent flow. In laminar flow, the flow rate through the valve is linearly related to the pressure difference. However, in a mixed state of laminar and turbulent flow, the flow rate increases with the Reynolds number, even with a constant pressure difference. Only in turbulent flow does the flow rate remain independent of the Reynolds number. Nevertheless, the selection of small-flow control valves still relies on traditional methods and calculation formulas. However, the calculated and actual values ​​deviate significantly. According to available information, below Cv=0.01, it serves only as a capacity indicator and has reference value. The actual flow capacity should be determined empirically.

As the flow capacity decreases, the valve's turndown ratio will decrease. However, it should at least be between 10:1 and 15:1. If the turndown ratio is smaller, flow regulation becomes difficult.

When valves are used in series, the pressure difference across the valve changes with the opening, causing the valve's operating characteristic curve to deviate from its ideal characteristics. If the pipeline resistance is high, the linear characteristic will become a quick-opening characteristic, losing its regulating ability. The equal percentage characteristic will become a linear characteristic. At low flow rates, due to minimal pipeline resistance, the above characteristic distortion is minimal, making the equal percentage characteristic practically unnecessary. From a manufacturing perspective, below Cv=0.05, it is impossible to produce an equal percentage lateral shape. Therefore, the main issue for low-flow valves is how to control the flow within the required range.

From an economic perspective, users may desire a valve that can simultaneously perform both shut-off and regulation, which is achievable. However, for control valves, the primary function is to control the flow rate; shutting off is secondary. It's incorrect to assume that a small-flow valve, with its very low flow rate, can easily achieve flow throttling when closed. International regulations generally specify leakage limits for small-flow control valves. When Cv is 10, the specified leakage limit for this valve is 3.5 kg/cm². Under atmospheric pressure, leakage is less than 1% of the maximum flow rate.
