Features Multi-position setup allows the actuator and linkage kit to be positioned in 45-degree increments, facilitating installation in confined areas. Adjustable anti-rotation slider allows one linkage to accommodate multiple sizes of valve bodies and electric actuators. Index markings on drive shaft and mounting bracket allow the valve to be positioned in increments from fully open to fully closed, providing visual indication of the current valve position during setup and operation. Installation requiring no special tools facilitates quick and easy installation. Thermal spacer between valve and linkage reduces temperature and condensation from the valve to the actuator. Dual-centering bearing design maintains accurate stem alignment eliminating side loading on the VG1000 Series Ball Valve stem and stem seal to ensure longer seal life (M9000-51x Series Ball Valve Linkage Kit only). Sturdy aluminum construction provides exceptional strength and stability (M9000-51x Series Ball Valve Linkage Kit only). Glass-reinforced thermoplastic resin provides superior thermal isolation between the valve and actuator, and meets Underwriters Laboratories Inc.® (UL) 94 5V Flame Class Rating (M9000-520 Series Ball Valve Linkage Kit only).
