Diaphragm valve straight through - DIAVAL Fig. S | Comeval

The DIAVAL® Fig. S diaphragm valve is a straight-through, bidirectional valve designed for controlling the flow of service fluids in abrasive applications, water treatment plants, and the process industry. It features a bolted bonnet and a seatless design, utilizing a diaphragm as the closure element, with a rising handwheel for operation. The valve is known for its easy and cost-effective maintenance, primarily through diaphragm replacement. It can be operated manually via a handwheel or with an actuator. The valve range offers diverse design combinations, including various materials for the body, linings, and diaphragms, and supports nominal sizes up to DN300 and design pressures up to PN16. It is suitable for applications involving water, process fluids, and abrasive media. The valve is certified with several declarations of conformity, including ATEX and EAC.
