High Pressure High Flow Diaphragm Valves
Brand: FITOK
FITOK DF Series high pressure, high flow diaphragm valves use a spring design, offering a high flow coefficient, ideal for high pressure and high flow applications. The cobalt alloy diaphragm ensures durability and corrosion resistance. These valves withstand a maximum working pressure of 241 bar. Manual and pneumatic actuators are available, and position sensors are offered for pneumatic versions. There are also several connection types, sizes and seat materials, depending on process requirements. They can also be supplied with different surface finish levels, from standard machining to high purity electropolishing, and with FC-01, FC-02 or FC-03 cleaning and packaging processes, according to system requirements. Main features:
- Ideal for high flow applications
- Metal-to-metal seal
- Spring-type design
- Cobalt alloy diaphragm with high strength and corrosion resistance, ensuring long service life
- Optional position sensors (normally closed or normally open) for pneumatically actuated valves
