Three lines of pressure regulators are available: pressure-reducing, back-pressure and vaporizing. Swagelok® regulators are used in a variety of applications such as sample conditioning systems, gas and liquid analysis systems, calibration and carrier gas cylinders and delivery systems, instrument air and specialty gas pressure control. Ten new models provide accurate, consistent delivery pressures to processes and equipment to reduce the likelihood of process variability and to protect sensitive equipment. Backpressure regulators include five new models. Both pressure reducing and back-pressure regulators are available in a variety of piston-type and diaphragm-type designs. Swagelok 31500 Aurora Rd.
