VICKERS VALVE PLATE R.H. ROTATION (MAC

Right-hand rotation is exactly what this valve plate is built for. Valve plate geometry is directional, meaning the internal porting is specific to one rotation orientation and won't function correctly if you swap in a left-hand plate. As long as your pump runs R.H. rotation, you're in the right place. It's a genuine Eaton Vickers OEM part, so it'll hold to the original dimensional tolerances your pump was built around. Just confirm your specific model configuration when ordering since these are available across multiple sizes.

Right-hand rotation signifies that the valve plate is specifically designed for Vickers piston pumps where the rotating group spins in a clockwise direction when viewed from the pump's drive shaft end. Ordering the correct rotation is crucial because the internal geometry of the valve plate is directional and won't function properly if installed in a pump with the opposite rotation.
