Series 564, DN12.5 Pressure Eliminator
- Flat-Face design
- Connection under pressure
- One-hand operated
CEJN Series 564 is a Flat-Face quick-connect nipple with a built-in pressure eliminator. The nipple is according to and exceeds the demands in the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The pressure eliminator allows for connection with residual/trapped pressure on the nipple side. The nipple Series 564 connects with couplings in Series 565, Series 566 and Series 562.
The pressure eliminator nipples are also available in four other sizes; DN 6.3 (Series 264), DN 10 (Series 364), DN 16 (Series 664), DN 19 (Series 764). For steel couplings in accordance with ISO 16028 see Series 565. Stainless steel versions of the standard are available in Series 566. Series 562 feature an interchangeable steel coupling designed for lower pressures.
