SV58-P20A Valve

SYMBOL:
SV58-P20A Valve symbol
DESCRIPTION
A solenoid-operated, 2-way, normally closed, piloted poppet-type, screw-in hydraulic
cartridge valve with integral neutral sensor, designed to function as a load-holding or
blocking valve in applications requiring low internal leakage.

OPERATION
When de-energized, the SV58-P20A acts as a check valve, allowing flow from 1 to 2,
while blocking flow in the reverse direction. The neutral sensor will transmit an "Off"
signal. When energized, the poppet lifts to open the 2 to 1 flow path. In this mode, flow
from 1 to 2 is severely restricted. The neutral sensor will transmit and "On" signal.

FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Integral position sensor, EMI/RFI CE-rated.
• Unitized, molded coil design.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
