The solenoid valve symbol SOL01 indicates it is a single-acting, spring-return valve. This valve is pilot-activated, indicated by the triangles at each side of the symbol. These pilot valves are efficient, using a small amount of air to move a large valve spool. However, a

pilot-operated and direct-acting. Types of WPRVs Pilot-operated valves have a sensing control pilot and main valve in one unit. These valves are typically used in commercial appli-cations such as schools, hotels and hospitals, as well as in industrial and municipal applica-tions and installa-tions that require more consistent pressure control

double solenoid) Forward stroke: • When PB1 is pressed, coil Y1 is energised and 5/2 way DCV changes over. • Piston travels out and remains in the final forward position until a signal is applied to coil Y2. • The 5/2 DCV will remain in the last position because it is double solenoid valve and has no return spring.
