African Valve is the best Pilot Operated Relief Valve Manufacturers in Nigeria. It is a type of valve that is used to protect the equipment from overpressure by releasing the excess pressure. It has a sensor which provides a signal to the main valve when there is excess pressure. The system pressure keeps the main valve closed, as the pilot valve vents some of this pressure to the atmosphere or a lower-pressure area, and when the pressure inside the valve increases the set point the valve opens and releases the excess pressure, and once the pressure gets normal it closes. 

They are designed to handle high pressure and can handle large amounts of pressure, they play a critical role in the operation and demand in the industries where dependable pressure relief and protection.
