PARKER Series MD04/MD06 Directional Control Valve. Part Numbers & Stamps Shown On Valve. Unit Part Number: 999401-24F. Stamp On Center Unit: 204000. Terminals on Solenoids: 3 (See Photos). Solenoid Markings: 494091, 12VDC (See Photos). Four-Way Valve (Series or Parallel). Fluid Viscosity: Premium Grade Hydraulic Fluid, Which Matches Viscosity Requirements Of The Pump. Temp Limits: Maximum Operating Temperature is 200 Degrees F. Applications: Series or Parallel. Series Circuit Valve- By positioning the valve with the cylinder ports up and the pressure towards you, solenoid “A” and cylinder port “A” will be on the left side. When solenoid “A” is energized, flow will be from “P” to “B”. Series circuits unload the pump flow to tank when all 4-ways are in the center position. Pump flow passes through each valve making the pressure drops additive. Series circuits have the capability, when energizing two valves, of positive motion of two functions by using exhaust flow from the upstream actuator. Cautions to observe when applying valves in series circuits are pressure and flow intensification from different cylinders and the effects of back pressure on upstream functions. Parallel Circuit Valve- By positioning the valve with the cylinder ports up and the upstream pressure port (pressure port without counterbore for an O-ring) towards you, solenoid “A” and cylinder port “A” will be on the left side. When solenoid “A” is energized flow will be from “P” to “B”. Parallel circuits have pressure blocked in neutral and are generally used with pressure compensated pumps or some type of unloading valve. Parallel circuits do not have the problems of pressure and flow intensification but will not insure motion of more than one actuator when two valves are energized at the same time. Solenoid Energized: 55 Milliseconds. Solenoid De-Energized: 75 Milliseconds. Response time is interval between initiation of electrical signal to the solenoid and the appearance (or loss) of pressure in cylinder port.
