Electronic Vacuum Regulator Valve

It seems like every pneumatic control valve company offers a line of electronic pressure regulators these days.

Electronic vacuum regulator valve. Body is nickel plated brass for good corrosion resistance. The type known as a thermionic tube or thermionic valve uses the phenomenon of thermionic emission of electrons from a hot cathode and is used for a number of fundamental. They throttle a high vacuum source to maintain a lower vacuum level in your system. The command signal is first sent to a small electronic regulator that produces a pilot signal to the reference port of the dome loaded equilibar vacuum regulator evr to control the process pressure.

As flow requirements change the diaphragm moves a few millimeters to open and close over some or all of the orifices providing. Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel mount nut. This eliminates the need for multiple controllers in. These valves can be used in open loop mode or closed loop mode.

Equilibar electronic vacuum regulators allow vacuum control through a computerized command signal. Electronic vacuum valves are available in traditional 4 20ma analog or in modern serial digital inputs. Valves are constant bleed style so they continually release small. Many of these devices can also be used to control vacuum through positive pressure in the same device.

Proportion air s core focus is manufacturing industrial and repeatable electronic air pressure regulators and electronic pressure control valves. Adjust the outlet vacuum level within the range. Like our unique back pressure regulator technology the equilibar vacuum regulator evr uses multiple orifices sealed by a flexible diaphragm instead of a single large valve seat the equilibar is dome loaded by a pilot regulator setting the vacuum setpoint. Tescom pressure regulators backpressure regulators instrumentation valves changeover manifolds controllers and pressure control systems are critical to the fluid and pressure controls of dozens of industry applications including many operations with extreme conditions or involving hazardous materials or processes.

In open loop a command signal from the main computer controller is sent to the electronic vacuum pilot regulator. A vacuum tube an electron tube valve british usage or tube north america is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. Automatic vacuum control using electronic vacuum regulator there are many applications where process vessels need to be maintained under vacuum control conditions with varying setpoints. Proportion air sets the benchmark for electronic control with vacuum pressure valves regulators.

Examples include vacuum drying vacuum distillation or vacuum extraction of essential oils and flavors.
