SYMBOL
DESCRIPTION
Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves.
OPERATION
When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
FEATURES
* A romote pilot relief on port 3 (vent) will control the valve below its own setting.
* Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
* Minimum stage orifice is protected by a 150-micron stainless steel screen.
* Back pressure on the tank port (port 2) is directly additive to the valve setting at 1:1 ratio.
* The main stage orifice is protected against contamination.
* Minimum setting is 75 psi (5 bar) for all spring ranges of E-RVBA
