The GEMÜ F40 2/2-way filling valve is designed for filling processes in aseptic and hygienic areas of application. Flow rates up to 6,600 l/h are possible depending on the version. The sealing concept of the valve is based on the GEMÜ PD design, whereby the actuator is hermetically separated from the medium. All actuator parts (except seals) are made from stainless steel. The filling valve is available in pneumatic design F40 (and electrical design F60). The pneumatic version is available with Normally closed and Normally open control functions. -Hermetic separation between medium and actuator due to PD sealing technology - High switching cycles (over 10 million) - No "lift effect" thanks to using the GEMÜ PD design - Customised block construction possible - Designed according to Hygienic Design guidelines - Compact design - High Kv value - CIP/SIP capable and autoclave-capable - FDA compliant as standard and suitable for contact with food according to Regulation (EC) No. 1935/2004 Very fast and easy maintenance thanks to quick locking system and innovative cartridge spare parts system Connection types:Clamp | Spigot Connection standards:ASME | DIN | EN Body materials:1.4435 (316L), block material | 1.4435, investment casting material Seat seal materials:PTFE Conformities:3A | ATEX | EAC | FDA | Reg.
