Three-way valves are designed to cut off the flow of the medium from the installation (system) to safety valves installed at outlet flanges. One of the safety valves is always connected to the installation (system). The intermediate position of the valve head allows for the working medium flow through two outlet connector pipes. It can be also used as a distribution valve and be adopted to other functions. Three-way valves are manufactured either with flange connections (ZTk type) or with an end to be welded on (ZTb). The casing is made from welded high resistance steel P355. Teflon gaskets P.T.F.E. are used to seal the closure and for external sealing.
Working parameters for ZTb 10-100, ZTk 10-100:
working pressure 25 bar, temperature range: – 40ºC / +150ºC
Working medium: ammonia, freons, LPG, air and other non-aggressive gases.
