ADCA DIAPHRAGM SENSING PRESSURE REDUCING VALVES P20DS DESCRIPTION The ADCA P20DS is a series of direct acting, spring loaded, diaphragm sensing balanced plug pressure reducing valves. These regulators are particularly suitable for general purpose applications where low flow and high temperatures are involved and have been especially designed for use with steam. MAIN FEATURES Compact design. Robust stainless steel diaphragm. Non-rising adjustment knob. Balanced valve plug. Completely machined from solid bar stock material. 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. Connection for external sensing line. Panel mounting. Steam, compressed air and other gases compatible with the construction. AVAILABLE MODELS: P20DS – 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. LIMITING CONDITIONS CE MARKING – GROUP 2 (PED – European Directive) PN 25 Valve model FLOW RATE COEFFICIENTS (m³/h) SIZE VALSTEAM ADCA Body design conditions Max. recommended reducing ratio We reserve the right to change the design and material of this product without notice.
