SDV Diaphragm Valves plastomer-lined DN15 – DN200 resp. ½" – 8" SDV Diaphragm Valves are ideally suited for Shut-off, Flow Control and Throttling of corrosive and abrasive process media in either liquid or gaseous state. Modular Design Diaphragm Valves SDV Series are available as DIN- or ANSI-Valves, with handwheel for manual operation as per standard. The sturdy design bodies are made of cast steel 1.0619 (WCB), epoxy coating RAL 5005 signal-blue or stainless steel casting 1.4408 (CF-8M), with resistant linings such as PFA or PFA-AS (conductive). Proven PTFE/EPDM-diaphragms assure faultless closing function at any time. Main Features • Heavy-duty, robust construction, maintenance-free • Bubble-tight shut-off throughout the full pressure and temperature range • Spindle protected against atmosheric corrosion • Force limiting device protecting diaphragm from cold flow and other deformations, high life cycle • Yellow sight indicator showing actual position of diaphragm • Easy replacement of components on site • Flanges acc. to DIN PN10/16 resp. ANSI 150lbs for installation into existing piping systems Conformity according to European Pressure Equipment Directive 2014/68/EU (PED) Sliding Spindle Body 1.0619/PFA, for external actuators Automated Valve Body CF-8M/PFA, with pneum. actuator, el. position indicator and solenoid valve Safety Padlock Operating Conditions © www.swissfluid.com
