Product Description The low flow electronic pressure regulator (electric air pressure regulator) is suitable for industries that require precise pressure changes at any time and monitor pressure values. Moreover, the electronically controlled pressure regulator price of B3-1A is economical to this extent that the user can afford it with no hassle. Similar goes for electronic gas regulators; it's a digital air regulator that possesses the ability to resist massive quality air pressure. Over and above, the electronic pressure regulator (electronic proportional air regulator) Arduino is an open-source electronics platform that is especially designed to make electronic machinery more accessible in this digital era. The digital air pressure regulator facilitates the users with the digital reading of the present output pressure value. Another useful feature is an air flow regulator with digital pressure gauge that allows users to measure the quantity of the pressure allotted to the mechanical device for its operation.   Available with 3 selections of input signal: 0-10VDc, 4-20mA, or RS485 Modbus. Monitor signals can be chosen from 1-5V, 0-10V, or 4-20mA. Our special design offers high pressure and high flow capability electronic air pressure regulators in unibody design.   For applications that require a high pneumatic flow rate, we offer the option of an air pilot volume booster to amplify downstream flow. For applications that require an external pressure transducer, there is also an option to link our pressure regulators to external sensors for closed-loop control. All our electronic pneumatic regulator have CE, SGS, RoHS certification with ISO13485 quality system. Applications: Laser cutting, leak tester, tension control, PET bottle molding machine, multi-stage pressure control, etc.   Applications for Electronic Pressure Regulators Spraying/ Painting Air Blowing Leak Testing Filling Pressure Artificial Heart Laser Cutting   FAQ session – Proportional Electronic/Digital Pressure Regulators What are the differences between Proportional Pressure Regulator, Electronic Pressure Regulator, Electro Pneumatic Pressure Regulator Electronic, I/P Converter, Digital Pressure Regulator, and air flow regulator with digital pressure gauge? They are the same products with different names. Where is the digital pressure regulators used? Digital pressure regulator is usually used for laser cutting, plastic blow molding machines, tension control equipment, tire making machines, etc. Is the pressure regulator resistant to dirt? No, it is not resistant to dirt particles. Please use dry clean air and filter with < 5 μm. Any restriction on mounting orientation? Electronically controlled pressure regulator Arduino is especially designed to operate mechanics. There is no restriction on mounting orientation; however, please be aware to protect the regulator from environmental water drop, oil, and welding slag.   Knowledge Base How Does a Proportional Pressure Regulator Work? A Proportional Pressure Regulator has many advantages over mechanical manual regulators. A manual regulator will maintain pressure downstream, most effectively with constant upstream flow rates. However, upstream flow and pressure will often fluctuate in most applications. Pumps and compressors deliver pulses, and the pressure will fluctuate with demand. When a mechanical pressure regulator lacks accuracy or can’t respond fast enough, the result is uneven pressure output. This simple device might be good enough when accuracy isn’t as crucial. However, a digital pressure regulator delivers better accuracy and stable output pressure by utilizing a control signal and the feedback signal to create closed-loop pressure control.   Uses of Regulators Electronic pressure regulators (electric air regulators) maintain a constant output pressure within a pressurized system even if there are fluctuations in the incoming pressure to the regulator. Mechanical pressure regulators are typically only adjustable by hand, limiting their usability in a digitalized process environment. When using an electronic gas pressure regulator with a digital control system, the precise output pressure is controllable via slight adjustments to the control signal. An internal pressure transducer creates a closed loop control device and offers a feedback voltage of the current output pressure. By reading this feedback signal from an electronic regulator, control systems can make real-time adjustments, greatly improving consistent pressure regulation in the most demanding applications.   The Working Process: Electronic pressure regulators (automatic air pressure regulator) are a big improvement over manual regulators; they are simple and very effective at allowing better control. An electronic air regulator uses a fill valve and a vent valve to maintain the outlet pressure at the desired set-point. A small inner pressure sensor monitors the output pressure and the digital controller adjusts the flow output of the internal valves to retain the required set-point (i.e. closed-loop control). That means that when you set the desired pressure, the regulator(pressure regulator digital) will maintain this pressure even with changing flow rates through the system. The internal pressure transducer gives immediate feedback to adjust the flow of either the fill or vent valve so the output pressure remains static.   When the control signal increases, the internal proportional pressure control valve activates, increasing pressure into an internal pilot chamber. When this happens, more of the inlet pressure passes through the proportional fill valve and into the pilot chamber. The pressure in the pilot chamber grows and causes the upper surface of the diaphragm to operate. Because of this, the air supply valve linked to the diaphragm opens, and a portion of the supply pressure becomes output pressure. This output pressure goes back to the control circuit using the pressure sensor. The fill valve will continue to slightly adjust until the output pressure is equivalent to the desired set-point of the control signal. Please check our video on: GennDih Enterprise. Co. Ltd

In pneumatic world, a proportional pressure control valve is used to control downstream air pressure with an electronic signal. The input electronic signal is proportional to the span of the output pressure. For example, 0-10VDc of command signal corresponds to the output pressure span of 0 - 10 bar, with linear proportion relationship. Type of Proportional Pressure Regulator Valve? Kao Lu offers three types of electronic proportional pressure regulator: pressure ranges from vacuum -1~0bar, low pressure 0~2bar, 0~4bar, 0~8bar, medium pressure 0~16bar, 0~30bar, up to high pressure 0~70bar. In the high pressure control, the resolution can reach 0.5~0.6 bar. Proportional Pressure Regulator Valve Working Principle? Proportional Pressure Control Valve adopts a closed loop design and consists of two solenoid valves, an internal pressure sensor and an electronic control; according to an analog signal input, one solenoid valve is used to control the air intake and the other is used to control the pressure. Both valves work together to achieve a precise proportional pressure control. The proportional pressure regulator adopts two types of input signals: 0-10VDC or 4-20mA, and three types of monitor output signals: 1-5V, 0-10V or 4-20mA.
