Condensate Drain Valves
Drain-AllŪ Condensate Drains have been the industry leader for over 20 years. The steam for the sootblower steam piping system 10 is conveyed from a steam source in the steam generator, typically a header connected to a bank of superheater or reheater surface, by means of piping 12 to a pressure reducing valve (PRV) 14. The PRV 14 is required because the sootblower steam pressure requirements are generally much lower than the available pressure at the steam source.
The output from pin (3) of the timer integrated circuit 33 is inverted by gate 34A and NANDed by gate 34B with the output from pin (3) of the timer integrated circuit 28, this output having first been drain valve fed through a filter composed of resistor 35 and capacitor 36. The filtered output from pin (3) of the timer integrated circuit 28 is also fed to the reset pin (4) of the timer integrated circuit 33.
Second temperature sensing means 30 are provided on the drain piping 22 as close as practical to the drain valve 24, to produce a second signal representative of the steam temperature at the drain valve 24. Advantageously, each of the temperature sensing means 28, 30 is a resistance temperature detector (RTD) selected so that its range will encompass the normally expected steam temperature range within its associated piping.
In particular, relay contact K2 closes and relay contact K1 opens when the first signal representative of the steam temperature at the source is less than the header setpoint temperature THDR, or when the difference in steam temperature between the source and drain, ΔT, is greater than or equal to the setpoint steam temperature, TSP.
The system of the present invention can be used to proportionally control the position of a modulating type of drain valve 24. For this purpose, line 76 is connected to line 40 for providing the signal representative of the difference in steam temperature between the source and drain, ΔT, through a dipswitch 78 to buffer amplifier unit 80. The output of the buffer amplifier unit 80 is provided along a line 82 and is an analog output proportional to the ΔT, and which would be used to proportionally control the position of a modulating type of drain valve 24.
With EC-Type Examination Certificate for use in explosive environments, these BEKOMAT condensate drains are approved for use in potentially explosive atmospheres condensate drain valve 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.
Drainage ceases when the condensate level falls back to the minimum level. Our New Jersey Meter Condensate Traps give you a fully automatic and completely dependable condensate removal from compressor tanks (receivers); air systems; and industrial steam systems.
Lubricant, metal particles, rust, and pipe scale are all separated and filtered out, but it's the drains that have to operate properly for the filters and separators to be successful in completing their task. 3-Weg Electric Ball Valve (bore >8mm):For larger flow rates, such as central heating, irrigation, compressed air etc.
Our Condensate Drain gives you fully automatic and completely dependable condensate removal from compressed air systems and industrial steam systems. Our zero air loss condensate drain valves look forward to meeting your expectations. Unlike traditional float drains, the operating mechanisms are isolated from condensate so no fouling or sticking occurs.
The use of intelligent level controlled drains to reduce compressed air wastage & leak reduction is an effective way to reduce compressed air wastage & power costs. The condensate drain automatically drains condensate from steam systems during start-up. This all-purposevalve removes condensate from compressors, receivers, dryers as well as from after coolers, filters and drip legs.
Exactly for the reduction of such malfunctions GESTRA has developed a self-operated pressure-controlled AK automatic start-up condensate drain valve. The condensate drain valve arrangement of FIG. These drains are also called Zero Air Loss” drains and have an electronic capacitive sensor monitoring the condensate level.
They play a crucial role in enhancing the longevity of the compressor unit and the entire compressed air system, including the sub components, driven equipment, and instruments. About 20% of these are valves, 13% are air-compressor parts, and 2% are air filter.
