Georg Fischer Diastar 025 Diaphragm Valve

The DIASTAR 025 has the highest closing forces in the portfolio of pneumatically actuated diaphragm valves and is available with the functions FC (fail safe to close), FO (fail safe to open) and DA (double-acting). The valve is thus used wherever high pipe pressures of up to 10 bar need to be controlled on on both sides.

Function

Pneumatic diaphragm valves from GF Piping Systems are used for regulating, as well as closing, controlling and monitoring volume flows. Especially when transporting contaminated, aggressive or abrasive media, this type of valve has decisive advantages thanks to its simple function and optimized construction. Only the valve body and diaphragm come into contact with the medium.

Applications 

• Control applications 

• Controlling pure and ultrapure media 

• Water treatment 

• Chemical dosing 

• Applications with higher viscosity and solids content

• Safe transport of aggressive media 

• Adapting closing forces to medium pressure through reduction of spring assemblies 

• High corrosion resistance 

• Maximum system safety 

• Safe maintenance and minimal downtime 

• Wide range of materials available 

• Broad spectrum of applications 

• Quick retrofitting through simple integration of accessories
