Diaphragm valves with integrated pneumatic actuators

GF Piping Systems has added the diaphragm valve type 604/605 with integrated pneumatic actuator to its product range. 
The valve’s compact design fits standard installation lengths. Its integrated pneumatic actuator with quick opening and closing times enables more than one million closing cycles over its service life. 

The actuator housing can be opened quickly for service due to the central housing nut. The connection with the valve body is full plastic without any metal parts.

Therefore all materials have the same temperature expansion coefficients, which prevents leakages and avoids re-torqueing of screws. 

Thanks to the optimised linear flow characteristics the kv value is up to 30 per cent higher than with comparable valves. The valve is available in DN15 with the pressure rating of PN6.

The valves are available in PVC-U, CPVC, PP-H and PVDF. Diaphragms in EPDM, FPM, PTFE/EPDM and PTFE/FPM enable the handling of aggressive media as well as neutral fluids.  

Valve type 604 can be mounted with true union connection matching all standard GF unions and inserts and solvent cementing. 

Valve 605 comes with a sealed or resealable nozzle. Both valves meet the standards ISO, BS, ASTM and JIS. 

The valves also feature unique QR code on the product leads to installation manuals, online training videos and certifications.
