PEMS6000-26-G2) is designed for ZEMS G2 exposed sensor water closet valves. It includes the top bracket and fasteners. ZEMS hardwired flush valves provide consistent and reliable motorized operation, detecting the user with precision for high-performance flushing operation. They feature a quiet GO BLUE diaphragm with a clog-resistant bypass and chloramine-resistant seals for an extended lifespan and lower maintenance costs.
