SX203 (N.O.)
20 litres/min (5 US GPM) 350 bar (5000 PSI)
SX203 / SX204 Directional Control Valve - 2-Way, 2-Position
Poppet
SX204
NORMALLY OPEN
(as shown)
NORMALLY CLOSED
To give on-off control of flows of 20 litres/min (5 US
GPM) and pressures up to 350 bar (5000 psi). Typical
usage includes the control of actuators in a hydraulic
system.
Standard aluminium (up to 210 bar*)
Add suffix ‘377’ for steel option
SX204 (N.C.)
Normally Open
De-energised; 2 to 1 – full flow, pressure difference
through the pilot orifice holds the main poppet open. 1
to 2 – restricted flow, main poppet pressure biased
onto its seat, pilot orifice open.
Energised; 2 to 1 - No flow, pilot orifice closed, main
poppet pressure biased onto its seat. 1 to 2 – full flow
when solenoid force overcome.
Normally Closed
De-energised; 2 to 1 – no flow, pilot orifice closed,
main poppet pressure biased onto its seat. 1 to 2 – full
flow when spring force overcome.
Energised; 2 to 1- full flow, pressure difference through
the pilot orifice holds the main poppet open. 1 to 2 –
restricted flow, main poppet pressure biased onto its
seat, pilot orifice open.
