Air safety valve 900 series

The 900 series consist of the following components: •Pressure switch, which transforms a pneumatic signal into an electric one. •impulse generator, which transforms a permanent pneumatic signal into an adjustable impulse from 0 to 10 seconds. •Pneumatic timer (n.C. or n.O.), which cuts or releases a pneumatic signal within an adjustable time. •Two hands safety valve, which allows a safety use of two hands pneumatic controls (for example two push-button 3/2 N.C. to a certain distance) excluding false signals in case of push-button or valve malfunction. •Flip – Flop: 5/2 ways valve, single signal actuated, commutes the outlet from 2 to 4 and vice versa at each puls. •For a correct functioning it’s important that inlet pressure be the same or lower than pilot pressure. •Oscillator valve, 5/2 – G 1/8″ with two logic functions “NOT” mounted on board, switches when the pressure in the connected cylinder exhaust chamber is reaching the threshold of “NOT”. •Signal amplifier, 3/2 – G 1/8″ N.C. valve actuated by weak signals but higher than 0.05 bar. •Progressive start-up valve, which is a device that is fitted in between valve or solenoid valve and cylinder allows a gradual filling of the chamber providing a low power cylinder movement. The progressive start-up valve is made of a flow control valve and a 2/2 N.C. valve with 6 mm nominal orifice. the valve is totally open when the pressure in the cylinder reaches 50% of inlet pressure.
