ADCA PRESSURE SUSTAINING VALVE PS46 (EN) DESCRIPTION The ADCA PS46 series pressure sustaining valves are single seated, diaphragm or piston sensing bellows sealed controllers, that operate without auxiliary energy. These valves are designed for use with steam, compressed air, and other gases compatible with the construction. These valves are particularly suitable for sustaining steam pressure in all energy and process systems where minimum upstream pressures must be kept under control. MAIN FEATURES Specially designed high durability bellows, providing pressure balancing and frictionless plug stem. Robust construction (fit-and-forget). Interchangeable actuators and adjustment springs. OPTIONS: Soft sealing in PTFE/GR for use with steam. Soft sealing in nitrile rubber for use with air and gases. Low-noise flow divider. Sensing pipe on body. Steam, compressed air and other gases compatible with the construction. Limited use with liquids. Consult manufacturer before installing the valve with liquids. AVAILABLE MODELS: PS46S and PS46ST or N – carbon steel. Suffix T: soft sealed with PTFE/GR. Suffix N: soft sealed with nitrile rubber. 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 PS46 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 * A water seal pot must be installed in the sensing pipe when operating with steam or liquids at higher temperatures.

ADCA HOW TO SIZE (USING Kvs) Please consult formulas on IS PV10.00 E or consult manufacturer. ORDER REQUIREMENTS Remarks: Never size the valve according to the pipe diameter in which it has to be fitted, but according to the actual flow required. Pipe sizing must also respect the maximum recommended flow velocities, according to the medium. HOW TO ORDER PS46 DN 32 PN 16 valve complete with spring Nº 60, A2A actuator, condensate vessel and copper sensing pipe. INSTALLATION Horizontal installation with the actuator vertically, pointing downwards. Installation with the actuator pointing...
