fitur-fitur
- Machined and epoxy coated ductile iron seat integrated in the body
- Rotork gearbox, IP67, with handwheel and position indicator
- Double eccentric design releases seal compression after only few degrees of opening resulting in low operating torque
- Disc firmly fixed to the shaft to prevent fluttering and a slight tilt allows for precise adjustment of the closed position
- All threaded connections are sealed with O-rings for protection against medium and environment
- CSB self-lubricating radial- and thrust bearings
- Replaceable shaft seals with two EPDM O-rings
- Shaft fully encapsulated in disc and sealed by gasket and O-ring
- Coating DN≤1600: Blue RAL 5017 FBE to DIN 3476, GSK and approved by WRAS-DVGW/W270/UBA, 250µm. Coating DN≥1800: 2-pack EP, WRAS approved, RAL5017 externally and ribbon blue or cream white internally, 250µm
- Drinking water approved by DVGW (DN≤1200) and WRAS (DN200-1200)
