Ürün Özellikleri
ON/OFF VANA

FFF pneumatic on/off valves are angle-seat valves with CF8M steel body, threaded or socket weld connections and a servo control made of 304 stainless steel. Seal on the valve seat is soft type, and can be made of different materials according to customer's needs. Tightness on stem is guaranteed by packing glands made of PTFE + graphite-loaded PTFE.
