Enclosure Manifolds EDM SeriesAS-Schneider EDM Series 2 Valve, 3 Valve and 5 Valve Enclosure Manifolds are manu-factured for applications that require the transmitter to be mounted in an enclosure for environmental protection. Modern process measurement instrumentation needs protection not only from the effects of sun, rain, frost, aggressive atmosphere or dirt but also from accidental damage or unauthorized access. The innovative design of the valve head units gives long service life and a smooth, low-torque operation. The AS-Schneider 2 Valve Manifolds, as standard, are rated to 420 bar (6,092 psi). AS-Schneider also provides the manifolds for sour gas service (acc. to NACE MR0175/MR0103 and ISO 15156), degreased and lubricated for oxygen service as well as manifolds for fugitive emission applications.
