JPR low flow pressure regulator and the JCYL and JCYL-2 are one and two-stage pressure regulators that come equipped with a CGA fitting and are used as cylinder or bottle-gas regulators. The JBP is the back pressure equivalent of the JPR. These products are used on very low flow applications such as those found in a research facility or to reduce pressure of gases from cylinders. They can also withstand very high pressure of 3600 PSIG on regulators. Jordan Valve Div. Richards Inds., Inc. 3170 Wasson Rd. Cincinnati, OH, 45209
