This safety control valve is designed to protect system by releasing pressure surges in water network elevation lines to atmosphere quickly which is caused by sudden changes in water speed due to pumps put into/out of service. When network pressure exceeds set point, valve opens by itself quickly and protects system by releasing over pressure. When the pressure decreases to normal level, it is closed slowly and automatically tightly without causing surge.
