Ariston Diverter Valve Tail Plate / Bush (0862 | R0862 | 248062)
The Ariston Diverter Valve Tail Plate / Bush Assembly (cross-referenced with part numbers 0862, R0862, or associated with the classic hydraulic manifold layout 248062) is a precision mechanical hardware component designed for the shared hydraulic blocks used across legacy combi boiler platforms, including several Ariston configurations. Positioned securely on the face of the mechanical 3-way diverter valve housing, this bush nut and plate component plays a vital role in locking internal operational pushrods, spindles, and sealing bushes in correct geometric alignment. It ensures flawless hydraulic distribution when switching between the central heating circuit and domestic hot water production.
Shaft Stability & Mechanical Alignment: Centers the internal moving pushrods precisely to eliminate off-center wobble, preventing uneven friction that can cause premature seal damage or a stuck valve pin.
High-Tolerance Fluid Barrier: Provides the exact compression required to seal internal O-rings and gaskets under variable system pressures, eliminating persistent weeping from the valve's connection point.
Heavy-Duty Construction: Fabricated from high-grade, resilient materials engineered to withstand corrosive system debris, scale accumulation, and continuous hot-and-cold thermal cycling.
Cross-Platform Compatibility: Features the precise engineering standards utilized in early brass-bodied combination valve blocks, providing an accurate, drop-in replacement to restore system pressure retention.
Compatible Applications:
Ariston Combi Mechanical Valve Blocks (utilizing shared brass manifold components)
Shared 3-Way Diverter Valve Assembly Designs (Part Nos. 248061 / 248062 / 0862 / R0862)
