Automatic discharge of air or gas from centrifugal pumps and suction systems to a central vacuum unit, e.g. vatec-Type TDV, TDES or AELZ.

Automatic discharge of air or gas from centrifugal pumps and suction systems to a central vacuum unit, e.g. vatec-Type TDV, TDES or AELZ.

Level-controlled gas discharge valve for automatic discharge of air or gas from siphon pipes via a pressure-controlled central vacuum unit, e.g. vatec-central vacuum unit type TDV.

Separator for evacuation of centrifugal pumps pumping clean or slightly contaminated fluids. The system is specially used in case of heavily gassing media (e.g. gasoline), media having considerable air and gas inclusions, as well as for evacuation of suction lines with relative peak points.

Automatic shut-off valve for pipelines to prevent gas flow.

Throttle valve for installation at the discharge side of centrifu- gal pumps serves for reducing the unloading process and to ensure higher purification in pump systems with priming sys- tems. The throttling aids evacuation processes by hindering the formation of air vortices at suction inlets.

Non-Return Valve for clean to lightly contaminated liquids. Flow in arrow direction.

Protective strainer fur succeeding piping and pumps.

Inlet nozzle for pump suction pipes.

Vertical mounted and membrane operated breaker valve to prevent back flow in discharge side siphon pipes.

2-step de- and aeration valve for sewage water pump discharge pipes. Due to a free suspended floater and dispense with lever, joints and pivot the valve is insensitive against solid and sedimentation.

2-way gas discharge valve for automatically exhausting of liquid filled components of installations, so as high points of discharge pipes, boiler, filter tanks etc.

Self controlled combinated ball type non return and deaeration valve to exhaust air and gas from pipes and vessels under vacuum or pressure (max. 2 bar) conditions by means of a vacuum pump.
