ABS Diaphragm Valves

ABS diaphragm valves and pneumatic DIASTAR actuators engineered by Georg Fischer deliver precise throttling, shut-off, and flow regulation in industrial piping systems. The corrosion-resistant ABS body paired with flexible diaphragms ensures total media isolation and reliable operation across chilled water, cooling, and water treatment networks. This range includes manual Type 514 and 515 valves along with pneumatic DIASTAR series (FC, FO, and DA configurations). Designed for seamless solvent cement jointing, these valves provide tight shut-off, high duty-cycle longevity, and zero metal contact with the process fluid.
