ADCA DIAPHRAGM SENSING PRESSURE SUSTAINING VALVE PS7 DESCRIPTION The ADCA PS7 series direct acting, spring-loaded diaphragm sensing pressure sustaining valves are designed for use on steam and compressed air and other gases compatible with the materials of construction. They are suitable for pressure sustaining applications where very small loads are involved. They are also specifically recommended to operate as pilot valves in combination with other pressure regulators. MAIN FEATURES Compact design. Stainless steel diaphragm. OPTIONS: 1/8” gauge connection on body. Top cap (adjustment screw with cover). External sensing connection. Low pressure top. Dome loaded version. Steam, compressed air and other gases compatible with the construction. AVAILABLE MODELS: PS7S – carbon steel. PS7SS – stainless steel. Horizontal installation. A “Y” strainer should be installed upstream of the valve. See IMI – Installation and maintenance instructions. FLOW RATE COEFFICIENTS (m³/h) SIZE LIMITING CONDITIONS Valve model Body design conditions CE MARKING – GROUP 2 (PED – European Directive) PN 40 Maximum upstream pressure Minimum upstream pressure Maximum 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 seating is used. Warning: A pressure sustaining valve is not a safety relief valve and must not be used for that purpose!
