The Basics information of parker sectional control valve
Every valve has the following elements: Inlet, Main relief, Work sections, Outlet, Section seals,Stud kit to hold the assembly in place.
The valve inlet is connected directly to the outlet coming from the hydraulic pump, and the valve outlet is connected directly to the tank. The main relief valve is generally installed in the inlet and controls maximum system pressure. The valve work sections connect the cylinders, motors, spreader valves or other auxiliary valves.
Work Section Types : Sections can be the following types: Single Acting (one work port) Double Acting (two work ports)
Actuators：Work sections can be actuated by four means: Manual Handles Air Actuators Electric Solenoids Hydraulic Pilot.
Work Port Relief Valves：Individual work section can have work port relief valves
screwed into the sides of the work sections and can control: Control pressure Reduce cavitation
Work port relief valves can be adjustable or fixed depending to the style.

Model V20 double-acting cylinder sections versus V20 motor spools cannot be visually determined simply by looking at the valves. It is important to keep the valves properly marked during the assembly process. It is recommended that a permanent M be marked on the motor spool so the installer will know the difference.
