Product Overview
The GEMU R690 25D7871141EDN is a pneumatically actuated diaphragm valve engineered for demanding process and industrial fluid control applications. Manufactured by GEMÜ, a globally recognized leader in sterile and industrial valve technology, this valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the working fluid from the valve mechanism and actuator. The R690 series is a straight-through, 2/2-way diaphragm valve designed for shut-off and control of neutral, aggressive, and contaminated liquids and gases. With a robust pneumatic piston actuator, the valve delivers reliable, fast-response operation in automated process lines, offering excellent chemical resistance, high flow capacity, and maintenance-friendly construction. Its design ensures minimal dead space, making it suitable for high-purity and industrial process environments where leak-tight shut-off and long service life are critical.
