 Relief valve, Pilot Operated, Spool Type with Reverse Free Flow
250 bar [3600 psi] • 120 l/min [32 US gpm]
DESCRIPTION AND OPERATION
This is a pilot operated, poppet type relief valve that relieves from port 1 to port 2 with an integrated reverse flow check valve from port 2 to 1. Due to its unique poppet design, this valve offers faster response than a typical pilot operated valve. It can be used to limit pressure in a system or on a service line of a directional valve. It maintains accurate pressure control with constant or varying flows, while also allowing make up flow through in the reverse direction

Logic Element Poppet, Double Blocking Closed, Vent to Open 315 bar [4600 psi] • 160 l/min [42 US gpm]
This is a 3-ported, normally closed, double blocking 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 but not from port 2 to port 1. Closing port 3 will prevent the valve from opening from port 1 to port 2. The area ratio between port 1 and 3 is 1 to 1 and port 2 is balanced between the seat diameter and the seal poppet diameter. 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.

Function: Logic Element, Normally Closed, Spool Type, Pilot to Close
Logic Element, Normally Closed, Spool Type, Pilot to Close 3S0 bar [S000 psi]• 1 SO I/min [40 US gpm] 
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.

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

Description: PSV10-NC-25-00-00-B-00
Function: Proportional Flow Control Valve, Spool Type, Normally Closed, Direct Acting, Non-Compensated
Proportional Flow Control Valve, Spool Type, Normally Closed, Direct Acting, Non-Compensated 260 bar [3800 psi]• 40 I/min [10.6 US gpm] 
This is a 2-way, spool type, normally closed, non-compensated proportional flow control valve. In the de-energized condition, flow is blocked in both directions. Energizing the coil will proportionally open port 1 to 2. Used in conjunction with a compensator, the valve will act as the control orifice for a pressure compensated flow regulator.

Proportional Pressure Reducing, Relieving, Pilot Operated, Normally Open to Drain 50 bar [725 psi] • 25I/min [6.6 US gpm] 
This is a pilot operated, proportional pressure reducing/ relieving valve.In the de-energized condition, the inlet port 2 is blocked, while the reduced pressure in port 3 will be at the minimum setting and open to the tank port 4.By energizing the coil, the pressure in port 3 will increase proportionally to the current applied.Flow through port 2 to 3 is restricted to limit the pressure in port 3.In the case of over pressurization in port 3,the spool will open port 3 to port 4, which acts as a relief valve to limit the pressure in port 3.These valves are ideal for clutch control or as pilot valves for large directional control valves.

[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)
