Basic Pneumatic Circuits - AutomationDirect
cdn.automationdirect.comfeeds a solenoid valve controlled by a PLC. 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

Proportional and Servo Valve Technology - Moog Inc.
www.moog.comSolenoid controlled, pilot operated proportional directional valves, sometime called two-stage proportional directional valves, use either of two schemes to control the position of the main spool. If the valve is an open loop valve, the pilot valve is actually a dual pressure reducing valve; two proportional pressure reducing valves are valve ...
