Product Description

The ADP series visually adjustable differential pressure bypass valves are self-operated control valves used to regulate the minimum flow rate through a piece of equipment, such as a small gas boiler, or to control the differential pressure in a central heating system.

Product Features

The ADP series visually adjustable differential pressure bypass valves serve as an alternative to electric hydraulic control valves. Their advantage is that they require no external power source and operate using the system's own pressure, effectively improving the safety margin of operation. They are safer and more reliable than traditional electric hydraulic control valves, eliminating the reliance on electricity and the risk of unit damage caused by electrical circuit failures. Furthermore, these self-operated differential pressure bypass valves are easy to install and cost-effective.
