Diaphragm Valve

GF Piping Systems has added 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. GF Piping Systems is a division of the Georg Fischer AG group of companies, which also includes GF Automotive and GF Machining Solutions.
