The Series consists of the 7300 and 2300 lines, both available in pipe and Namur-mounted models. Constructed of hard-coat anodized aluminum, brass (7300 Series only), and stainless steel, they come in both three-way normally closed and four-way directional-control versions. The valves are compatible with lubricated or dry air, and a range of inert and other gases. Pressure ranges are 30 to 150 psi and temperature ranges of 40 to 75°C. Cycle life is up to 2 million with lubricated air. A seal/spool/cage assembly reduces internal friction, and a conversion plate lets users alter the valve's function onsite from four-way to three-way operation. A captured pilot exhaust eliminates external contamination and the need for additional piping connections.
