Relief valve – Direct operated type RD Thread adjusting type T P Relief valve – Direct operated type Overview This direct operated type relief valve, which is a seat type relief valve, prevents momentary pressure increase of the hydraulic circuit and at the same time is used for load holding. Type indication Features 1. This valve is very responsive and is optimum especially for a relief valve. 2. As a cartridge type is available, it can be incorporated in a manifold in a compact way. 3. As this valve is of seat type, it has less internal leakage compared to the balance type relief valve. 4. As this valve is provided with the chattering preventive mechanism, its operation is stable. Relief valve – Direct operated type Nominal dimension 6, 8, 10, 15 20, 25, 30 Connection method G = G thread connection type GO = G thread connection type (based on JISB2351 0 type) R = R thread connection type P = Gasket connection type C = Cartridge type Nominal dimension 6 8 10 15 20 25 30 Series number: 10 RD G GO R P C Shape of pressure adjusting part 1 = Handle adjustment 2 = Thread adjustment (with cap) 3 = Handle with key adjustment (nominal dimension 6, 8, 10 only) Type of hydraulic oil No symbol = Mineral based hydraulic oil V W = Phosphate ester based hydraulic oil = Fatty ester based hydraulic oil Water-glycol based hydraulic oil (Note) In the case of the cartridge type, “No symbol” and “W” are identical, and therefore, there is no “W”. Highest adjustment pressure 25 = 2.5 MPa 25 kgf/cm 2 50 = 4.9 MPa 50 kgf/cm 2 100 = 9.8 MPa 100 kgf/cm 2 200 = 19.6 MPa 200 kgf/cm 2 315 = 30.9 MPa 315 kgf/cm 2 400 = 39.2 MPa 400 kgf/cm 2 630 = 61.7 MPa 630 kgf/cm 2 Nominal dimension 6 8 10 15 20 25 30 Highest adjustment pressure 25 50 100 200 315 400 630 (Note) As the minimum set pressure differs depending on the flow rate, refer to “Pressure override characteristics”. 2-2
