SDV Diaphragm Valve

Reliable and simple in construction

The key features of the Swissfluid SDV Diaphragm Valve are reliability and simplicity in construction. Its cavity-free and self-draining design make our SDV Diaphragm Valve the preferred choice for chemical and pharmaceutical applications. The simple maintenance and the possibility to replace the diaphragm assembly without having to remove the valve from the line makes this valve also a popular choice in other industries.

We offer our SDV Diaphragm Valve in accordance with DIN specification (EN 1092, EN 558-1, cat. 1) as well as ANSI (ASME B16.5, MSS SP-88). The standard configuration consists of a 1.0619 cast steel body (per ASTM A216 WCB), fully lined with PFA and a PTFE/EPDM diaphragm. This economically priced combination affords the highest chemical resistance against virtually all chemicals. Swissfluid also offers this valve in 1.4408 SS (CF-8M; AISI 316) with a choice of liners such as PFA-AS (anti-static), polypropylene or PVDF, and an optional low diffusion, triple-layer diaphragm.

Our SDV Diaphragm Valve can be factory-equipped with pneumatic or electric actuators, making it suitable for automatic on-off applications or in connection with positioners for use as control valves. Actuators are available with polypropylene housings (economical, corrosion-proof, light weight) or with sturdy steel enclosures.
