Return Valve is built out of brass with a viton seal and a 1/4" compression fitting. This check valve is designed to keep a positive pressure on the system for immediate starts and quick shut offs. This is factory pre-set and needs no adjustment.
Our training horses are content, comfortable and ready to work, thanks to our Shoo-fly Automatic Insect Control System!
