ADCA DIAPHRAGM SENSING PRESSURE REDUCING VALVES P20D DESCRIPTION The ADCA P20D is a series of direct acting, spring-loaded, diaphragm sensing and balanced plug pressure reducing valves. These regulators are designed for use with compressed air, water and other gases and liquids compatible with the construction materials and valve design. They are suitable for pressure reducing applications at the point of use in laundry and dyeing machines, food industries, sterilizers, etc. MAIN FEATURES Compact design. Non-rising adjustment knob. Balanced valve plug. Completely machined from solid bar stock material. Ultrasonically cleaned. OPTIONS: Leakage line connection. Gauge connection on body. Different soft valves for liquids and gases. Top cap (adjustment screw with cover). Degreased for oxygen application. Panel mounting. Self relieving. Compressed air, water and other gases and liquids compatible with the construction. AVAILABLE MODELS: P20D – stainless steel, diaphragm sensing. Female threaded ISO 7 Rp, ISO 228 or NPT. Flanged EN 1092-1 PN 40. Flanged ASME B16.5 Class 150 or 300. Horizontal or vertical installation. See IMI – Installation and instructions.
