Problem The piston rod of a pneumatic cylinder (single-acting/double-acting) is to extend when a push button valve is actuated. When the push button valve is released, the piston rod retracts. Draw the pneumatic circuit diagram using direct control circuit.
Solution 1: With single-acting cylinder using direct control circuit.
Solution 2: With double-acting cylinder using direct control circuit.
Problem 2 The piston rod of a pneumatic cylinder (single-acting/double-acting) is to extend when a push button valve is actuated. When the push button valve is released, the piston rod retracts. Draw the pneumatic circuit diagram using indirect control circuit.
Solution 1: Control of a single-acting cylinder using indirect control circuit.
Solution 2: Control of a double-acting cylinder using indirect control circuit.
Problem 4 The piston rod of a double-acting cylinder is to extend when a push button valve 1.2 and a roller operated valve 1.4 are actuated at the same time. The piston rod retracts when the one or both valves are released. Draw the pneumatic circuit diagram.
Solution:
Problem 5 The piston rod of a double-acting cylinder is to extend fully forward when a push button valve 1.2 is actuated momentarily. The piston rod retracts at high speed when a push button valve 1.3 is actuated. Draw the pneumatic circuit diagram.
Solution:
Problem 7 The piston rod of a double-acting cylinder is to extend at a slow speed when a push button valve is actuated. The piston rod retracts at a normal speed when the valve is released. Draw the pneumatic diagram using direct control circuit. Solution 1: Using supply-air throttling
Solution 2: Using exhaust-air throttling
Problem 8 The piston rod of a double-acting cylinder is to extend fully forward when a push button valve 1.2 is actuated momentarily. The piston rod retracts when a push button valve 1.3 is actuated. The forward speed and return speed could be adjusted separately. Draw the pneumatic circuit diagram.
Solution:
