Rotary Timing Valves provide flow and pressure from a stationary input to a rotating output, and provide on/off flow control where a fixed sequence pattern is maintained. This valve can replace conventional methods used to control flow, such as cams, solenoid vales and switches. They are commonly used on multiple position index tables which repeat the same cycle through every rotation.
The stationary component of the valve has the timing sequence machined into the sealing surface. As the rotating outlets pass through the timing sequence, flow is automatically turned on and off depending on their orientation.
Typical applications:
A rotary union is used to transfer liquids and gases from stationary supply lines to rotating equipment. The media flow through a rotary union is continuous and uninterrupted. External valves are needed to control the flow. All of the passages are independent, so SRS rotary unions are suitable for transferring both fluids & gases through the same rotary union without cross contamination.
