ADCA PRESSURE SUSTAINING VALVE PSW46B (EN) DESCRIPTION The ADCA PSW46B series pressure sustaining valves are single seated, diaphragm or piston 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: 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: INSTALLATION: A1A, A11A, A3A, A4A and P55 – carbon steel. A2A and A21A – SG iron or carbon steel. See IMI – instructions. CE MARKING – GROUP 2 (PED – European Directive) PN 16 With sensing pipe on body VALSTEAM ADCA We reserve the right to change the design and material of this product without notice.

ADCA LIMITING CONDITIONS Valve model Body design conditions Maximum upstream pressure Maximum downstream pressure Minimum upstream pressure Maximum operating temperature Maximum hydraulic factory valve body test Remark: Other soft materials and temperature limits on request. Warning: A pressure sustaining valve is not a safety relief valve and must not be used for that purpose! Actuator model Maximum operating pressure (bar) Maximum operating temperature * With liquids at higher temperature, the sensing pipe should prevent exceeding the maximum operating temperature of the actuator.
