Constant Flow Valve Principle | Instrumentation Tools - Inst Tools
Constant Flow Valve keep flow rate of gases or liquids at constant value even when the supply or load pressure changes. Control valve with diaphragm automatically acts following the change of pressure.

恒流量阀（constant flow valve）是2000年公布的机械工程名词。 定量供油或气的流体静压轴承中，使各腔进油或气量保持某固定值的器件。 《机械工程名词 第一分册》第一版。 [1] 恒流量阀（constant flow valve）是2000年公布的机械工程名词。
Constant flow valves are reliable, self-regulating and self-cleaning valves that provide a pre-set constant flow for fluids regardless of pressure. Maric System constant flow valves are used to rationalise and improve your product or process and reduce your
Constant flow valves - Bertfelt Teknik AB
Bertfelt is the leading manufacturer of BT-Maric constant flow valves for industrial use. The BT-Maric constant flow valves (sometimes called flow restrictors, flow limiters) are designed to deliver a pre-determined, constant flow rate for water and …
Constant Flow Valves 7 (6) Principle & Operation Refer to Figure 1 for design and operation of ASAHI AV Flow Control Valve. When the upstream fluid pressure, P 1 is introduced at the flow control orifice, it exerts a corresponding pressure on the upper surface of the flange on the piston type valve plug. Likewise, the downstream pressure, P2 ...

是具有恒流量功能的调节阀，它是将自力式的压差控制装置和流量调节装置组合而成的阀门，其工作原理是：用压差控制装置，控制并稳定流量调节装置前后的压差，从而使阀门前后的压差大于恒流启动值之后，通过的流量不再随着阀门前后的压差而变化，在压差控制的范围内，通过阀门某一开度的流量能够自动保持恒定，流量的变化只需 调节阀门 开度即可实现，与阀门前后的压差无关。 同一工作原理的阀门有的称为“ 动态平衡阀 ”，有的称为“自力式流量控制器”或“自力式流量 …
The Maric flow control valve is designed to deliver a fixed, pre-set, constant (maximum) flow of water, irrespective of pressure differential across it, (within a given range). This means constant flow rate, irrespective of fluctuating pressure upstream or downstream of the valve.
Constant Flow Valves - Asahi-America
Automatic flow control valve that can be manually set for different flow rates. The valve adapts to changing line pressure to maintain a steady flow rate in the downstream piping (see “Principles of Operation”) without automation (neither electricity nor an air supply is required).
CONSTANT FLOW VALVE[1/2-4inch]（15-100mm） | ASAHI …
The CONSTANT FLOW VALVE accurately controls the flow rate to within ±6％ of the full scale value and offers high rangeability (set value for maximum flow rate/set value for minimum flow rate). Using the handle, the flow rate setting on the valve can be changed at will.
Flo-Trol ® Flow Control and Flow Regulator Valves - Flomatic …
The Flomatic ® Flo-Trol ® automatic flow control valves are designed to give constant flow over a wide pressure range. The valve design has no moving part; rather a self-cleaning flexible orifice that varies in size with applied pressure so that a constant flow rate is maintained. Flow rates are maintained to within ±15% between 15 and 125 ...
