The HV is a\u00a0pilot operated\u00a0vacuum regulator. The vacuum signal applied to the pilot port commands the HV to control at that same vacuum level in a precise 1:1 relationship. Pilot pressure can be provided by\u00a0a manually adjustable mechanical vacuum regulator or with an electronic vacuum regulator when automation of the pressure control is desirable.<\/p> <table class=\"simple\"> <thead> <tr> <th width=\"50\">Part #<\/th> <th>Port Size<\/th> <th>Pilot Port<\/th> <th>Max.

HV series is able to control vacuum accurately at these low pressures because of its unique direct diaphragm sealing design. A flexible membrane diaphragm is the only moving part and is used to directly create the seal against a field of small orifices. There are no springs or sliding seals to create any internal friction. The diaphragm&#8217;s large area and supple materials allow the HV to respond to small changes in pressure. The unique sensitivity of Equilibar&#8217;s supple diaphragm gives a significant advantage over slow-reacting butterfly valves and other control valve mechanisms. One key advantage is the nearly instantaneous reaction time (in the range of 10 milliseconds). The diaphragm quickly and automatically responds to any change in the system vacuum level that creates any pressure difference between the controlled system vacuum and the vacuum command being applied to the HV pilot port.<\/p> <p>Since the dome-loaded design matches the inlet pressure to the pilot or set-point pressure applied to the 1\/4&#8243; dome port, the unit can also be used with positive pressures. This type of control is often referred to as a back pressure valve or back pressure regulator. The HV will match the setpoint pressure provided to the reference port in a precise 1:1 fashion regardless if it is a positive or negative pressure. This allows the HV series to control pressures both above and below atmosphere and vacuum through positive pressures. Absolute and gauge pressure references are available.<\/p> <p>The HV series is manufactured from welded stainless steel plate. Using welded plate metal construction instead of machined bar stock allows\u00a0the HV Series to avoid the higher weight and costs of bar stock or cast construction.
