Timing using a Manual Push-Pull Valve Push-Pull valve can be used to start and stop system manually while providing timing to the circuit. A 5/2 valve can also be used when operating a double acting cylinder, or for alternating outputs. |

Converting an On Delay timer output to an Off Delay output On delay timer signals can be converted to an off delay signal with the use of an interposing normally open 3/2 air piloted valve. |

Timing using a Momentary Start Signal A timing sequence can be established from a momentary pressure signal using an interposing pneumatically operated valve. The most common signal used is from a pushbutton, but inputs from limit switches, foot pedals or other devices can be used to initiate timing. The size of the air piloted valve determines the air volume output. |

Continuous Cycling Timer Circuit Continuous cycling is accomplished by the use of 2 timers operating a double air piloted valve. Off and on times are dependent on the type and set time of timers used. The size of the air piloted valve determines the air volume output. The position of the air piloted valve determines the start up of the timing sequence. If the timing sequence must be restarted in a specific order, a reset circuit must be added at port 12 of the air piloted valve to move it to the start position prior to resuming operation. |

Continuous Cycling Timer Circuit Using PT Timers Continuous cycling is accomplished by the use of 2 timers operating a spring return air piloted valve. Off and on times are dependent on the time range of the timers used. The size of the air piloted valve determines the air volume output. |

Timing using Start-Stop Pushbuttons Separate start-stop pushbuttons can be used in conjunction with a double air piloted valve and an 'or' logic valve to control a timing circuit if required. A wide selection of types and colors of pushbuttons is available to meet design requirements. The size of the air piloted valve determines the air volume output. |
