Electronic pressure regulators control and maintain a desired pressure level in a system or application. They use electronic sensors and controllers to regulate the flow of fluid or gas, allowing for precise and accurate pressure control.
Unlike traditional mechanical pressure regulators, an electronic pressure regulator does not rely on springs or diaphragms to control pressure. Instead, they use electronic components such as sensors, transducers, and solenoids to monitor and adjust the pressure as needed.
Electronic pressure regulators can be used in a wide range of applications, including industrial manufacturing, automotive, aerospace, and medical devices. They offer several advantages over traditional pressure regulators, including faster response times, greater accuracy, and the ability to program and control pressure remotely.
Types of Electronic Pressure Regulators
There are several types of electronic pressure regulators, each with their own unique characteristics and applications. Here are some of the most common types:
Digital electronic pressure regulators
These regulators use a microprocessor to control pressure. They can be programmed with multiple setpoints, and some models offer PID control for even greater accuracy.
Proportional electronic pressure regulators
These regulators, like SMC ITV 1010-33T 1N 1000, use a proportional solenoid valve to adjust the pressure. They are often used in applications such as pneumatic automation and robotics.
Piezoelectric pressure regulators
These regulators use a piezoelectric crystal to control pressure. They are well-suited for applications that require precise pressure control.
Vacuum electronic pressure regulators
These regulators, like SMC ITV 2090-2125N5-Q, control vacuum pressure in applications such as semiconductor manufacturing and vacuum packaging. They use electronic sensors and valves to maintain a desired vacuum level.
High-pressure electronic regulators
These regulators, like SMC ITVH2020-03N2CL4, control high-pressure fluids or gasses, such as those used in oil and gas exploration or hydraulic systems. They often use high-strength materials and advanced sensors to withstand the rigors of high-pressure applications.
Series ITVX2000 high pressure electro-pneumatic regulator provides stepless control of air pressure to an electrical signal. They have an easy to read digital pressure display and a power consumption of 3 W or less. The new series has a 5.0 MPa maximum supply pressure.
Series ITV electro-pneumatic and electronic vacuum regulators control air/vacuum pressure steplessly in proportion to an electric signal. They are light weight in design with a bright and easy to read LED display. The monitor output is available either as analog output or switch output. The ITV series is IP65 equivalent.
A hybrid regulator is created from a regulator and a solenoid valve with the electro-pneumatic regulator series VY1. A maximum effective area of 670mm² (2B) can be covered by the combination of an ultra-compact electro-pneumatic pilot valve (22.4 X 30 X 39) and a 3 port, high-capacity exhaust main regulator (VEX1*00 series). Having the amplifier built into the electro-pneumatic pilot valve, only an external (24V DC) power supply and (1 to 5V DC) signal voltage need to be connected making handling simple. Using the VVEXB/2/4 series, a maximum 10 station manifold is possible.
Electro-pneumatic regulator series IT has a variation for each output flow rate. In addition to the existing conduit entry, a DIN connector is available. A dedicated exhaust port (M5) is installed to remove air from the nozzle. The IT series comes with monitor signal output and shock/ vibration resistance.
Series IC, controller for electro-pneumatic regulator converts digital input signal into analog output signal. It has a maximum 10 bit parallel input signal and a 4 point preset output pressure. This series is mainly used in combination with the series ITV0000 w/o a display function.
PVQ series, compact proportional solenoid valve, was designed by SMC with a direct poppet construction. This construction enables low leakage, while de-energized. PVQ series has been used in applications such as air blow, flow control, hand piece control for dental unit and other respiratory equipment, as well as, cooling for laser machinery etc.
A proportional control valve system provides the ability to infinitely control the position of the internal spool assembly which increases or decreases the amount of flow or pressure being released from the valve. SMC offers 2 types of proportional control valves, a pressure type VEP which controls secondary pressure by varying the current through the solenoid, and a flow rate type VEF which controls air flow by varying current through the solenoid.
The 5 port electro-pneumatic proportional valve, Series VER can be used to switch and actuate a cylinder and to perform stepless pressure control of port A through electric signals. The VER2000 (direct operated type) is available with 1/4 or 3/8 port size. The VER4000 (internal pilot type) and the VER4001 (external pilot type) are available with 3/8, 1/2 or 3/4 port size. Thread types include Rc, G, NPT or NPTF. The VER is also available without a sub-plate.
