Set your flow rate and then adjust it as necessary; these valves maintain flow rate despite pressure changes in the system.

Turn the handle to direct flow between ports.

To set the pressure, unscrew the cap and turn the adjusting screw.

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.

Direct flow with an electronic signal.
