The story is all too common. In condensate drain valve arrangements described in published United Kingdon patent application No. 2038032A as for use in steam systems, sensing elements for insertion in the steam systems for triggering electronic circuits for controlling operation of the drain valves of the arrangements are electrical sensing probes operated in dependence upon condensate being present, or not present, at the level of the probe.
No matter how much you spend on that fancy new compressed air system, VFD'S pin-stripes and flashing lights notwithstanding, not spending condensate drain trap a little effort with your drain choice could cause you no end of headaches and increased operating costs for years to come.

2B) which is connected between the timer integrated circuit 28 and the transistors and solid state switches 32. This monitoring circuit 24A monitors the lengths between successive valve opening operations, and triggers the circuit 24 to open the valve 22 for a predetermined time if the interval between successive valve opening operations exceeds a predetermined time.
When the probe is no longer submerged the output from the first inegrated circuit 27 changes back to the 6 KHz oscillation which initiates a timing cycle, simultaneously taking timer circuit pin (3) positive and de-energising the coil 31 of the solenoid valve, which closes.

With EC-Type Examination Certificate for use in explosive environments, these BEKOMAT condensate drains are approved for use in potentially explosive atmospheres according to ll 2G Ex ib llB T4 Gb. THE BVS 03 ATEX W 124 certificate of confirmity approves the applicability for explosive hazardous areas.
At the conclusion of a timing cycle, and until initiation of the next timing cycle, timer circuit pin (3) is at zero volts and the transistors and solid state switches generally referenced 32 in the electronic circuit 24 switch the coil 31 to its energised condition.
Drain-All® Condensate Drains have been the industry leader for over 20 years. As the condensate level drops, the magnet moves away and the valve closes again. Indirect operated solenoid valves need a pressure differential over the inlet and outlet port for proper operation.

Numatics EDV Series condensate drain valves eliminate the manual draining of pneumatic air lines. Condensation is a serious problem in compressed air systems and is one of the major reasons for failures and breakdowns. The solid state timer initiates a drain cycle by energizing the valve coil that opens the valve and allows the condensate to drain.
The two settings need to be adjusted to the size of the compressed air system in such a way that all condensate is discharged with a minimum loss of air. This mechanism provides a more reliable and robust sealing than a traditional float operated drain valve.

This condensate, if not drained properly, will damage equipment and decrease the overall efficiency of your compressed air system. The experienced team from Air System Products and CDA Systems are committed to providing superior condensate drains and excellent customer service.
We are at the forefront of producing and supplying good condensate drains for compressor condensate discharge. Condensate drain valves remove condensate from the air system without losing excessive compressed air and without shutting down the system. No air waste - timer operated - open tube - none (yes that is a drain choice).
It's ideally suited to apply on applications where power is not available or wanted The operation is automatic and there is no compressed air lost during the condensate discharge cycle. The purchase price of these cost effective valves is recovered in less than 1 year by the elimination of wasted compressed air due to incorrect timer valve settings.
