805314919 - 2-WAY - SVP08-NC-00-00-B-00 - DANFOSS
Solenoid Valve, 2-way, Poppet Type, Normally Closed, Pilot Operated 230 bar
[3300 psi] • 35 l/min [9 US gpm]
OPERATION AND DESCRIPTION
This is a 2-way, 2-position, poppet type, pilot operated, normally closed solenoid valve. In its de-energized condition, flow passes from port 1 to 2 but is blocked in the opposite direction. When energized, flow passes from port 2 to 1 but is restricted in the opposite direction. Some models have the option of a filter at port 2. Due to the low leakage provided by the poppet design, these valves can be used to hold loads in position and bypass excess oil to tank

Solenoid Valve, 2-way, Poppet Type, Normally Closed, Pilot Operated with Reverse Free Flow
230 bar [3300 psi] • 35 l/min [9 US gpm]
 OPERATION AND DESCRIPTION 
This is a 2-way, 2-position, poppet type, pilot operated, normally closed solenoid valve. In its de-energized condition, flow passes from port 1 to 2 but is  blocked in the opposite direction. When energized, flow passes from port 2 to 1 and from 1 to 2. Some models have the option of a fllter at port 2. Due  to the low leakage provided by the poppet design, these valves can be used to hold loads in position or to interrupt a pressure line where flow normally  passes in both directions.
