1 TECHNICAL BULLETIN CA4-A4-TB IO Registered Company MODEL CA4 and A4 ULTRA HIGH PURITY PREURE REDUCING REGULATOR Dome Loaded: 3/4-2 (DN20 DN50) Models CA4 and A4 are high performance dome load ed, flow-to-open pressure reducing reg u la tors with in ter nal pres sure balancing piston-cylinder that provides medium flow capacity and high pressure drop capability. FEATURE Model CA4 (Investment ) All T wetted trim materials. Electro-polished. Tube-end connections. APPLICATION For electronic grade and other ultra high purity fluids. For either gaseous or liquid service. Most common fluids are high purity oxygen, nitrogen, hydrogen and argon. (A special vari a tion including Hastelloy C in ter nal parts is available for anhydrous HCl; consult factory.). High pressure capability. Body Finish -15 μ-in. Ra average surface finish is standard. (Opt μ-in. Ra average surface finish avail able for Barstock body only). In-line maintenance.
