The new Pneumatic Diaphragm Valves of GF Piping Systems represent a revolution in terms of safety, efficiency and simplicity. Like the manual valves, the new DIASTAR also has a central union nut. This connection is non-corrosive, is temperature stable, and has a high pressure rating up to 240 psi (when used with water). Because of the doubled Cv values, the energy expenditure can be reduced considerably. At the same time, the flow characteristic is very linear and thus ideal suited for control applications. DIASTAR Ten: Optimally suited for all standard applications to 10 bar (150 psi) and including an assortment of accessories. Type 10 Pneumatic Diaphragm Valves 1/2" through 2" Sizes
