ADCA DIAPHRAGM SENSING PRESSURE REDUCING VALVE P7 DESCRIPTION The ADCA P7 series pressure reducing valves are direct acting, spring loaded, diaphragm sensing balanced plug regulators designed for use with steam, nitrogen, compressed air, water and other gases and liquids compatible with the materials of construction. Particularly suitable for general purpose applications where low flow and high temperatures are involved. Also specifically recommended to operate as a pilot valve in combination with other pressure regulators. MAIN FEATURES Compact design. Robust stainless steel diaphragm. Precise milibar control. OPTIONS: 1/4” gauge connection on body. Top cap (adjustment screw with cover). External sensing connection. Low pressure top. Dome loaded version. Bar stock stainless steel construction. Steam, compressed air and other gases compatible with the construction. AVAILABLE MODELS: P7SS – stainless steel, diaphragm sensing. Horizontal installation. See IMI – Installation instructions. FLOW RATE COEFFICIENTS (m³/h) SIZE LIMITING CONDITIONS CE MARKING – GROUP 2 (PED – European Directive) PN 40 Valve model Body design conditions Maximum upstream pressure (steam) Maximum upstream pressure (gases) Maximum downstream pressure Minimum downstream pressure * Maximum design temperature * 0,07 bar with low pressure top (limited at 7 bar inlet). The low pressure diaphragm should be fitted for outlet pressures from 0,07 up to 0,5 bar. Pressure and temperature limiting conditions may change if soft sealing is used.
