OVERPRESSURE PROTECTORS FOR PRESSURE GAUGES

OVP Description

Specifically designed to protect the pressure gauge from damage caused by overpressure exceeding the pressure gauge measuring range. Completely automatic, the valve closes and blocks consequently the circulatory to the pressure element to a pre-set value. After decrease of pressure by about 25% below the preset value, valve opens and allows again circulation. The pressure limiting valve, is also normally employed between gauges and diaphragm seals.
