ADCA PRESSURE REDUCING VALVE RPW45B (EN) DESCRIPTION The ADCA RPW45B series pressure reducing valves are single seated, diaphragm sensing proportional controllers that operate without auxiliary energy. Designed for use with water, compressed air and other liquids and gases compatible with the construction. MAIN FEATURES Pressure balancing through robust piston design. Soft sealing to meet tight shut-off requirements. Robust construction (fit-and-forget). Interchangeable actuators and adjustment springs. OPTIONS: Low-noise flow divider. Sensing pipe on body. Water, compressed air and other liquids or gases compatible with the construction. AVAILABLE MODELS: RPW45BG – SG iron. RPW45BS – carbon steel. RPW45Bi – stainless steel. Flanged EN 1092-1 PN 16 or PN 40. Standard PN 16 DN 65 flanges are supplied with 4 holes. 8 holes, according to EN 1092-1/-2 on request. AVAILABLE ACTUATORS: A1, A10, A12, A3 and A4 – carbon steel. A2 and A21 – SG iron or carbon steel. A1i, A10i, A12i, A2i, A21i, A3i and A4i – stainless steel.
