Of course, control of the primary pressure is possible, as well as control at the terminal end!
A regulator that can control the pressure at the end by being placed between a vacuum valve and a vacuum pad.
It is specially designed to control the inlet pressure very stably under significantly different input conditions.
EVR maintains precise control despite changes in supply vacuum and flow rate. The Equilibar precision vacuum regulator operates differently from traditional vacuum control valves. They use a flexible diaphragm as the only moving part. This diaphragm seals directly against the orifice of the internal valve, eliminating the "stiction" commonly seen in traditional vacuum control valves that rely on dynamic O-rings or wiper-type seals. Equilibar's design is frictionless and can control vacuum with very high resolution. Let's learn more about how it works.
Ultra-high sensitivity vacuum regulator. It reliably controls low vacuum areas near atmospheric pressure.
The Fairchild vacuum control regulator has extremely high sensitivity characteristics. It can control from a shallow vacuum near atmospheric pressure to a maximum of -736 kPa. The product series consists of model 16 and the high flow model 1600A, both of which excel in repeatability and guarantee stable control. For more details, please contact us or download the catalog.
Electronic vacuum regulator
Vacuum control is performed by command signals from a computer. The command signals are first sent to a small electronic regulator, from which a pilot signal is generated and sent to the reference port of the dome-shaped Equilibar vacuum regulator (EVR) to control the process pressure. Equilibar offers a series of high-precision electronic pressure regulators that provide this pilot reference signal. The QPV ultra-high resolution model and the EPR-30Hg model allow for precise adjustments due to their minimal hysteresis and deadband. These regulators can be used in open-loop mode or closed-loop mode. In open-loop mode, the vacuum setpoint is sent to the electronic pilot regulator by the computer signal, and the pilot regulator supplies the commanded pressure to the EVR reference port, maintaining the process vacuum very close to the setpoint. In open-loop mode, slight variations in vacuum pressure occur as the flow rate increases.
