Non-leak Pilot Check Valve Max Operation 7.0MPa Pressure Maintaining Type Special Treatment Surface to Resist Rust
Features:
When the pressure supply of pressure source is cut off, the pressure can be kept unchanged until the oil pressure is supplied to the oil control port.
Type:
Modular Model
Operating pressure range 2.5 ~ 7.0MPa
Ordering Code:

| 1 | Series | |
| 2 | Pressure Code ; | 2 : Operating Pressure Range 2.0 ~ 7.0MPa |
| 3 | Circuit Symbol | A: A port check ;W:A/B Port Check |
| 4 | Pressure Maintain Valve/ adjusting set code | Blank:No Pressure Maintain Valve 4R: With Pressure Maintain Valve, adjusting Set Pressure Range 3.5 ~ 8.0 MPa |
| 5 | Operating Pressure (Only with Pressure Maintain Valve) | Please inform us of operating pressure (Supply pressure to P-port). (Please inform us with proper unit symbols.) Please refer to the specification for relief set pressure. |
Note:
Blank : Without Pressure Maintain Valve
4MPa → (4.0MPa) With Pressure Compensating Valve, Operating Pressure (P Port Supply Pressure):4MPa → (4.0MPa
Cautions:
1.Please take consider of pressure drop caused by hydraulic temperature drop in the use of holding the hydraulic pressure of A2(B2) port while stop the hydraulic supply to A1(B1) port
2.This pressure relief valve is used for relieving the amount of hydraulic pressure by which of volume increases because of hydraulic temperature rise.
This product can not be used for relieving the supply pressure that is out of relief set pressure range.
3. Note for pressure compensating valve : When it has back-pressure at T port, there is a possibility that it is not able to do relief action normally. Please contact us.
