E-EHPR08-33 Proportional pressure reducing/relieving cartridge valve
SYMBOL
DESCRIPTION
The E-EHPR08-33X is a direct-acting, spool-type, proportional, pressure reducing/ relieving valve. The regulated pressure is proportional to the input electrical current. EHPR08-33X free flow from port 1 to port 3 when no current is applied to the coil. With coil energized, port 2 is connected to port 1. Increasing current to the coil will increase the control (reduced) pressure proportionally. If pressure at port 1 exceeds the setting induced by the coil, pressure from port 1 port 1 is relieved to port 3.
OPERATION
The E-EHPR08-33 free flow from 1 to 3 when no current is applied to the coil. When the coil is energized, 2 is connected to 1. Increasing current applied to the coil will increase the control (reduced) pressure proportionally. If pressure at 1 exceeds the setting induced by the coil, pressure from 1 is relieved to 3.
Note: back pressure on port 3 becomes additive to the pressure setting at a 1:1 ratio.
FEATURES
* 12 and 24 volt coils standard.
* Optional waterproof E-Coils rated up to IP69K.
