Condensate removal from gas piping systems is necessary to protect piping and equipment from possible damage caused by corrosion or water hammer. In addition, water lying in low spots in piping can restrict gas flow resulting in increased pressure drop within the system. In addition to all low spots, Varec Biogas drip traps should be installed frequently along horizontal piping runs for convenient removal of accumulated condensate.
The Varec Biogas 247 Series Drip Trap is suitable for working pressures up to 100 psig (688 kPa). For systems with lower pressure ratings, see the product data sheet for Varec Biogas 246 Series Low Pressure Drip Traps.
The Varec Biogas 247 Series Drip Trap is designed to prevent gas from escaping while draining. The doubleseal ball plug valves and locking lever isolate the gas line connection before opening the drain port.
Condensate accumulates in the drip trap reservoir and is drained manually by operating the valve handles. When all accumulated condensate has been drained, the handles are returned to the “fill” position and locked in place.
