Cylinders - Lifting/Lowering, Single-Acting (2)

The example shows circuits with proportional valves for lifting and lowering a single-acting cylinder.

• 2-way, solenoid-operated poppet valve:         DT*A 
• Pilot-operated proportional throttle:                FP*K 
• Proportional flow control :                                FP*C 
• 2 stage solenoid-operated poppet valve:          DF*A       
• 3-way solenoid-operated directional valve:      DM*A
• Logic valve:                                                        DK*C

Benefits of this circuit arrangement

• Fig.1 shows two 2/2 way solenoid valves DT*A to hold, lift or lower a cylinder. A proportional throttle valve FP*C  (0- 10 gpm) controls the lifting or lowering speeds of the cylinder.
• Fig. 2 has the same functionality as the above, but for higher flow rates. The logic valve DK*C (piloted by a 2/3 way DM*A) and a 2/2 way solenoid poppet valve DF*A hold, lift or lower the cylinder. 
• The pilot operated proportional throttle valve FP*K with a flow rate of 0 - 60 gpm (@ 200 psi 200 psi P) controls the lifting or lowering speeds of the cylinder.
