URMC series is a check valve module typically used with relief valves to prevent reverse flow during pump start-up. Model code URMC-06-S1 indicates:
- 06: Size
- S1: Cracking pressure 0.035 MPa
Type: Check valve module (stacking type)
Mounting: On manifold block (no subplate)
Size: 06
Max Working Pressure: 21 MPa
Rated Flow: 100 L/min
Cracking Pressure:
- S1: 0.035 MPa
- (Options: S2: 0.35 MPa, S3: 0.53 MPa, S4: 0.88 MPa)
Weight: Approx. 5.9 kg
Fluid Compatibility: Mineral oil, water-glycol, phosphate ester (F3 option)
Ports: P, T, A, Y
Mounting Bolts: M16 (Torque: 90–110 N·m)
Note: Vent port of relief valve cannot interface with gasket surface; for multi-stage pressure setting use TCG50-80 series.
