Butterfly valves

The lugged and wafer butterfly valves are designed for installation between two flanges according to EN 1092-2. The neck is extended for insulation purposes. Higher nominal sizes are available on request.
For central heating and cooling systems with closed circuits. For operation with non-aggressive, harmless media , e.g. water or water-glycol mixtures according to VDI 2035 / ÖNORM 5195.
Body made of nodular cast iron, spindle and disc made of stainless steel.

Spare parts for butterfly valves

Strainers - Spare parts

Sludge separators

Sludge separators continuously remove smallest dirt particles without significantly increasing the flow resistance. A strong magnet retains magnetite. When the magnet is pulled out, the magnetic particles fall into the sump and can be rinsed out via a ball valve without interrupting operation.
For central heating and cooling systems with closed circuits. For operation with non-aggressive, harmless fuids, e.g. water or water-glycol mixtures according to VDI 2035 / ÖNORM 5195.

Air vents

For central heating and cooling systems with closed circuits. For operation with non-aggressive, harmless media, e.g. water or water-glycol mixtures with a max. glycol content of 30% according to VDI 2035 / ÖNORM 5195.

Body made of brass.
