Armstrong CD-33S disc-type traps American Armstrong CD-33S disc-type traps, Armstrong thermodynamic speed trap is a kind of time-delay device operating on the principle. It has only one moving part, the disc is. Due to the very light and compact, so this trap in small venues to meet the requirements of the work place. In addition to simple disc valve structure, small features, but there are many other advantages, such as: water shot, when opening the valve can release all the condensate, and the ability to work in a stable intermittent purging process. Controlled disc traps work, depending on the changes in pressure in the chamber of the disc. As long as cold condensate flow, Armstrong CD-type traps will open. When steam or flash steam reaches the inlet orifice, the flow rate increases, the disc is pressed against the valve seat. Increasing the pressure of the control room so that the disc quickly close. The heating chamber and the valve cover machined out of the shallow grooves on the disc control annular pressure is reduced. Once the system reaches a certain temperature, the bleed groove to control the frequency of emission Unique heating chamber traps Armstrong's controlled disc type steam trap has a unique heating chamber, which the disk and the whole package in the control room inside. From the heating chamber to the trap outlet controlled vent control frequency emissions. That is, the frequency of emission control from the trap design itself, from environmental conditions (rain, snow, cooling, etc.) effects. CD-33 / CD-33C thermal power disc-type traps Armstrong CD-33 Series Disc type traps can control the emission frequency of the trap, the trap frequency by reducing emissions, Armstrong CD-33 Series traps have a longer than average life of a disc-type traps. By optimizing the performance of the trap, to ensure a substantial reduction in maintenance time and steam costs. CD-33 Series is designed with three discharge ports, to ensure the stable operation of the disc, thus extending the life of the trap, Armstrong CD-33 Series traps displacement designed specifically for the following applications: constant pressure environment large steam mains drainage, process equipment and HVAC heating equipment. CD-33L (low-emission) trap is designed for low-emission applications, such as steam mains drainage and steam tracer drainage. And other types of discharge excessive compared to disc-type traps, CD-33 series has a longer life. According to series review Armstrong disc-type traps, see the following directory and choose the series you want from the top menu. CD-33 Series Disc type traps maximum steam pressure 4.2MPa ... Maximum Displacement 1134kg / hr CD-3300 Series disk-type trap all stainless steel with 360 ° connector maximum vapor pressure 4.2MPa ... Maximum Displacement 363kg / hr CD-40 and CD-60 Series controlled disc-type traps carbon maximum steam pressure 4.2MPa ... Maximum Displacement 1295kg / hr CD-72S series Disc Steam Traps maximum pressure 1,010 psig (70 bar) ... maximum displacement of 1,800 lb / hr (816 kg / hr) Armstrong CD-72S Series disk trap operating frequency is adjustable. By reducing the operating frequency of the trap, the Armstrong CD-72S series trap than other disc traps last longer. With the trap performance optimization, maintenance time and steam costs can be significantly reduced. CD-72S series is designed with three drain, ensure stable disc operation to extend trap service life. Armstrong CD-72S series of traps specifically designed for the following applications: constant pressure steam mains drainage, process equipment and HVAC heating equipment. Advantages: three outfall design of the control disc operating frequency to minimize wear and tear reinforced base and anti-frost disk can heat welding Armstrong Steam Traps, American Armstrong Armstrong steam trap is the main channel, steam tracing lines, plus Ideal for casing, coil heated storage tanks, tank, and duplex flat iron machine versatile. CD-type traps such as installed outdoors and when the weather conditions are cold, we recommend that the valve on the bonnet insulation or a heat shield configuration.
