Electric Valve Actuator
Connecting the blue control wire opens the valve in 16s. Connecting the brown control wire closes the valve in 16s. If both control wires are disconnected, the valve will remain In the current position. This way the position of the valve can be regulated. Never connect the blue and brown control wires at the same time, as this will damage the ...
Valve-Regulated Lead-Acid Batteries: Basics, Performance, and …
VRLA batteries, also known as sealed regulated lead-acid batteries, use sealed and valve-regulated technology to effectively control gas release and moisture loss, offering longer lifespans and more stable performance than conventional lead-acid batteries. The working principle involves two key processes: charging and discharging.

Understanding Pressure-Control Valves
The pilot-operated relief valve operates in two stages. A pilot stage, which consists of a small, spring-biased relief valve (generally built into the main relief valve), acts as a trigger to control the main relief valve. However, the pilot may also be located remotely and connected to the main valve with pipe or tubing.
