Economic Long runner – the diaphragm valve type 604/605
GF Piping Systems adds the new diaphragm valve type 604/605 with integrated pneumatic actuator to its extensive product range. This long runner – available beginning of October 2015 – combines compact design with best flow performance for an economic price-performance ratio. 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 long service life. That is what GF Piping Systems calls a durable hard worker. The valve is flexible in its operating modes and offers fail safe to close (FC), fail safe to open (FO) and double acting (DA) options.
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 percent higher than with comparable valves. The valve is available in DN15 with the pressure rating of PN6.30
The wide range of materials offers the highest adaption and resistance to chemical fluids and environments. 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. That makes them even more flexible and reliable for all your applications. Valve type 604 can be mounted into your system with true union connection matching all standard GF unions and inserts and solvent cementing. The valves meet the standards ISO, BS, ASTM and JIS.
