Favorite

The 0331 valve is a direct-acting, media-separated pivoted armature valve. It is available in 3/2 and 2/2-way versions. As a 3/2-way version, it can be used as a distributor or mixing valve.

Various diaphragm material combinations and methods of operation are available depending on the application. The standard brass housing satisfies all European drinking water requirements. Stainless steel (316L), PVDF, polypropylene and PEEK housing versions complete the offering. The solenoid coils are moulded with a chemically resistant epoxy. The 0331 is equipped with manual override for commissioning and testing.

For reduced energy requirements all coils can be delivered with electronic power reduction or as an impulse version.

The switching status can be indicated with position feedback as a binary or NAMUR signal. In combination with a plug in accordance with DIN EN 17301-803 Form A, the valves satisfy protection class IP65/67 - in combination with a stainless steel or plastic housing NEMA 250 Kat.4X.

Features:
  • Direct acting, medium separated valve up to orifice DN 4
  • Maintenance-free pivoted armature technology
  • Vibration resistant, screwed block coil system
  • Suitable for aggressive alkali solutions and acids
  • Service friendly, robust manual override
  • Explosion proofed version
