ADCA DIAPHRAGM SENSING PRESSURE SUSTAINING VALVES PS4 DESCRIPTION The ADCA PS4 is a series of direct acting, spring-loaded diaphragm sensing, pressure sustaining valves designed for use with compressed air, water and other gases or liquids compatible with the construction. The valve main purpose is to maintain the upstream pressure under control in applications where small loads are involved. These valves are also specifically recommended to operate as pilot valves in combination with other pressure regulators. MAIN FEATURES Compact design. External diaphragm sensing connection. OPTIONS: Different soft valves for water and gases. Gauge connection on body. Compressed air, water and other gases and liquids compatible with the construction. AVAILABLE MODELS: SIZES: PS4S – carbon steel. PS4i – stainless steel. 1/2" to 1". CONNECTIONS: Female threaded ISO 7 Rp or NPT. INSTALLATION: Horizontal installation. A “Y” strainer should be installed upstream of the valve. See IMI – Installation and maintenance instructions. CE MARKING – GROUP 2 (PED – European Directive) PN 40 Valve model Body design conditions Maximum upstream pressure Minimum upstream pressure Maximum design temperature * * Others on request. Warning: A pressure sustaining valve is not a safety relief valve and must not be used for that purpose!
