Shop Crossover Circuit Blanking Cover Plates

Cover Plates (also known as blanking plates, blocking plates, or cap-off plates) are used to cap off a pattern after a surface-mounted component is removed. 

They are also used to cover an extra pattern to be utilized in the future. Aluminum models rated to 3000psi, and ductile iron models are rated to 5000psi. 
Available in D03, D05, and D08 styles.

Crossover plates (COP) are also referred to as flushing plates, and allow flow from Pressure to working port A, and working port B to tank. 
They are typically used when flushing oil through the hydraulic system, enabling oil to reach the actuator.
