Directional

DMDFMAN - 3-WAY - DMDFMAN - SUN Hydraulics
This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.

The accumulator sense, pump unload pilot valve is used to sense pressure in an accumulator at port 1 of the valve and when the pressure at port 1 reaches the valve setting, port 2 connects to port 3 to vent a relief valve and unload the pump. This valve has a 20% ratio between unload setting and reset; when pressure at port 1 falls below 80% of the valve setting, port 2 is blocked from port 3 and the pump will come back online to recharge the accumulator. This valve requires a separate check valve between port 1 and the pump. Another version of the accumulator sense, pump unload valve, QCDB, includes a free-flow check valve for pump flows under 12 gpm (50 L/min)

CAPACITY: CAPACITY: 10 L/min
Ventable, bypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit. A vent port (port 4) allows these valves to be controlled remotely.

Solenoid Valve, 2-way, Spool Type, Normally Open
230 bar [3300 psi] • 16 l/min [4.2 US gpm]
OPERATION AND DESCRIPTION
This is a 2-way, 2-position, spool type, direct acting, normally open solenoid valve. When de-energized, flow can take place from port 2 to 1 and from 1 to 2. In its energized condition, flow is blocked in both directions. The valve will be subject to normal spool leakage dependent on the pressure dfference between the ports. They come standard with a push pin manual override. These valves can be used to interrupt a pressure line where flow is expected to pass in both directions in the energized condition. 

Proportional Directional Valve, 4-way, 3-position, Spool Type, Non-Compensated
250 bar [3600 psi] • 60 l/min [16 US gpm]

Solenoid Valve, 2-Way, Poppet Type, Normally Open, Pilot Operated with Reverse Free Flow230 bar [3300 psi] • 35 l/min [9 US gpm]
OPERATION AND DESCRIPTIONThis is a 2-way, 2-position, pilot-operated poppet-type solenoid valve, normally open in its de-energized state.When de-energized, flow is allowed in both directions— from port 2 to port 1 and from port 1 to port 2.When energized, flow is permitted only from port 1 to port 2, while flow in the reverse direction is blocked.
The poppet design minimizes leakage.Certain models offer an optional filter at port 2 and are supplied as standard with a push-pin manual override.
Typical applications include:

Load holding when the valve is energized


Interruption of a bidirectional pressure line


Fail-safe bypass of excess oil to the tank

Solenoid Valve, 2-Way, Poppet Type, Normally Closed, Pilot Operated230 bar [3300 psi] • 80 l/min [21 US gpm]
OPERATION AND DESCRIPTIONThis is a 2-way, 2-position, pilot-operated, poppet-type solenoid valve, normally closed in its de-energized state.When de-energized, flow is allowed from port 1 to port 2, while flow in the opposite direction is blocked.When energized, flow is allowed from port 2 to port 1, while reverse flow is restricted.

Some models are available with an optional filter at port 2.Thanks to the low leakage design of the poppet construction, these valves are ideal for applications requiring load holding or for safely diverting excess oil to tank.

SVP10-NO
Solenoid Valve, 2-way, Poppet Type, Normally Open, Pilot Operated
230 bar [3300 psi] • 80 l/min [21 US gpm]
This is a 2-way, 2-position, poppet type, pilot operated, normally open solenoid valve. In its de-energized condition, flow can take place from port 2 to 1 but is restricted in the other direction. When energized, flow can take place from port 1 to 2 but is blocked in the other direction. Leakage is kept to a minimum due to the poppet design. Some models have the option of a filter around port 2, and these come standard with a push pin manual override. These valves can be used to hold loads in position when energized or bypass excess oil to tank in a fail-safe way.

Solenoid Valve, 3-Way, 2-Position, Spool Type240 bar [3500 psi] • 60 l/min [16 US gpm]
OPERATION AND DESCRIPTIONThis is a 3-way, 2-position, direct-acting solenoid valve with a spool-type design.In the de-energized state, port 1 is open to port 2, while port 3 is blocked.When energized, port 3 is open to port 1, and port 2 is blocked.
These valves can be configured for normally open, normally closed, or selector functions.They feature an open transition during shifting, which helps reduce pressure spikes when changing flow direction.

Always verify the valve’s operating parameters to ensure suitability for your specific application.

Logic Element, Normally Closed, Spool Type, Pilot-to-Close350 bar [5000 psi] • 150 l/min [40 US gpm]
DESCRIPTION AND OPERATIONThis is a 3-port, normally closed, spool-type logic element with pilot-to-close functionality.When port 3 is open to tank, flow is allowed from port 1 to port 2.Flow from port 1 to port 2 is otherwise blocked unless the pressure at port 1 exceeds the spring setting.
Applying pilot pressure to port 3 increases the required opening pressure at port 1 at a 1:1 ratio.
This valve is ideal for use as a pressure compensator, bypass valve, or pilot-to-close element in regenerative hydraulic circuits.

SHUTTLE 1/4"G – SHUTTLE – SHUTTLE IN-LINE 1/4"G ALUMINIUM – FLODRAULIC

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

[3300 psi] • 50 l/min [13.2 US gpm]
This is a 4-way, 3-position, spool type, direct acting solenoid valve. In the center condition, ports 2 and 4 are closed while port 3 is connected to port 1. By energizing one coil, port 3 opens to 2 and port 4 to 1. When energizing the other coil, port 3 opens to 4 and port 2 to 1. This valve provides a directional control function with a neutral de energized state allowing the inlet flow to pass to tank or to another function while the work ports are blocked. It can be used in any hydraulic application where an actuator needs to be controlled in both directions. Always check the operating envelope to make sure the valve will work under the required application conditions. Port 1 is not intended for use as inlet (Tank only)

Logic Element, Normally Closed, Poppet Type, Vent to Open
350 bar [5000 psi] • 60 l/min [16 US gpm]
DESCRIPTION AND OPERATION
This is a 3-ported, vent to open, poppet type logic element with port 1 connected to port 3 through an orifice. By opening port 3 to tank, flow can pass from port 1 to port 2 or from port 2 to port 1. Closing port 3 will prevent the valve from opening from port 1 to port 2, but flow can still take place from port 2 to port 1. The area ratio between port 1 and 3 is 1:2 and the ratio between port 1 and 2 is also 1:2. By controlling the flow or pressure out of port 3, the valve can be used as an on/off valve or in a pressure control function. 

Logic Element, Normally Closed, Spool Type, Pilot to Close
350 bar [5000 psi] • 150 l/min [40 US gpm]
DESCRIPTION AND OPERATION
This is a 3-ported, normally closed, pilot to close spool type logic element. By opening port 3 to tank, flow can pass from port 1 to port 2. Flow is blocked from port 1 to port 2 unless the pressure is high enough in port 1 to overcome the spring set pressure. Applying pressure to port 3 will increase the pressure required in port 1 to open the valve by a factor of 1 to 1. This valve is ideal for use as a pressure compensator, bypass valve, or a pilot to close valve in regenerative circuits.

Description: CP300-4-B-0-0-080
Pressure Compensator, Restrictive Type 210 bar [3000 psi]• 40 I/min [11 US gpm] 
This is a 3-ported spool valve, where port 3 is connected to port 2 and port 1 is the pilot port. The spring chamber is connected to port 3 through an orifice. When port 3 is connected to the outlet of a control orifice and port 1 is connected upstream of the orifice, the valve functions as a restrictive pressure compensator. When the pressure drop across the orifice is equal to the spring set pressure, the spool restricts flow from port 3 to port 2 and compensates for any change in pressure difference across the valve.
