Pneumatic timers, typically used where no electrical power is available within purely pneumatic systems, or often sited where electrical power is deemed to be dangerous, pneumatic timers are considered intrinsically safe within these areas.
Pneumatic timers, in most cases, are designed to accept a continuous air input signal, the process value is then displayed mechanically by a timing hand or figure wheel, upon timeout the status of a directional valve changes signalling other devices.
Other pneumatic timers operate via a volume fill or vacuum decay technology and typically do not show a process value, they are quite tricky to set and often referred to as ‘Set-it Forget-it’ pneumatic timers, usually sited inside a control panel, calibrated once for a particular task, and rarely adjusted again.
We offer several types of a pneumatic timer; these can be base or panel mounted with 4mm push-in, M5 or 1/8 NPT threaded connections. Time ranges vary from 0.2 to 3 seconds up to 100 hours or 99999 minutes (digital versions). Upon reaching a preset value, the status of a 5 or 3 way (normally open or closed) valve will change, removal of air from the control port or a pulsed signal to the reset port (digital pneumatic timers) will return the valve and reset the timer ready for a new start signal.
We have many years of experience with pneumatic timers; we know precisely what timer best suits your application. Our product portfolio is unmatched offering design flexibility, and our application knowledge is extensive. Our range of pneumatic timers are fully interchangeable with all other manufacturers; they are competitively priced and usually available from stock.
