ASCO 8210-8211-V-5825 Valve Actuator Rebuild Kit

ASCO 8210-8211-V-5825 Valve Actuator Rebuild Kit restores ASCO's Series 8210/8211 Red-Hat solenoid valve actuators to reliable operation by replacing worn internals and seals. The kit's contents include the key components needed to reassemble the bonnet and diaphragm sections: four valve bonnet screws, a bonnet gasket, a body gasket, a valve bonnet stem gasket, a stem spring, and a stem pin, plus the core/diaphragm sub-assembly that seats inside the valve body. Lubrication is required for the body and bonnet gaskets during installation to ensure proper seal and movement. Rebuild kits are identified by the rebuild kit number stamped on the valve nameplate, and the V-5825/R6 formulation is associated with this series in ASCO maintenance literature. The kit is designed for use with ASCO Red-Hat general-service 8210/8211 valves and is intended to refresh actuation force, sealing integrity, and overall performance in industrial control and fluid-handling applications. By replacing worn diaphragms and seals rather than the entire valve, maintenance teams can extend service life and reduce downtime without guessing at compatibility, since the parts are manufactured to ASCO's specifications and fit precisely with the corresponding valve family.
