Problems solved by technology
Another problem with known proportional pressure controllers is that it is difficult to achieve zero pressure at the outlet port of the proportional pressure controller even when the outlet port requires a zero pressure condition
Failure to create zero pressure at the outlet port of a proportional pressure controller can negatively affect the operation and / or performance of the pressure control device

A proportional pressure controller includes a body having an inlet port, an outlet port and a discharge port. The fill valve is in communication with pressurized fluid in the inlet port. The dump valve is in communication with pressurized fluid from the fill valve. The inlet poppet is opened by pressurized fluid passing through the fill valve. When closed, the discharge poppet isolates pressurized fluid from the discharge port. When the inlet poppet valve is open, the outlet flow passage is in communication with pressurized fluid and with the outlet port and the discharge / outlet common passage. An isolation valve assembly selectively isolates fluid flow to and from the inlet port or the discharge port to achieve a zero pressure condition.
Description
technical field [0001] The present disclosure relates to proportional pressure controllers suitable for use in pneumatic systems, and more particularly to proportional pressure controllers with isolation valve assemblies. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Proportional pressure controllers typically include a main internal valve that moves to allow pressurized fluid to be exhausted to the pressure control device. Such proportional pressure controllers regulate the operating pressure of the pressurized fluid at the pressure control device. A solenoid operator is usually used to change the position of the main valve. This configuration adds weight and cost to the proportional pressure controller and requires a higher current to cause the main valve to change position. [0004] Known proportional pressure controllers are also generally susceptible to system ...
