Product Description
Designed to protect pressure instruments from over pressure exceeding the specified pressure range by sudden & excessive pressure fluctuation from surge or spike.
This device blocks the higher pressure exceeding the allowed value, until it comes back to normal, when system pressure becomes normal.
Hence this device safeguards the pressure instruments, gauges, switches or transmitters by blocking extra high pressure.
Widely used in mechanical engineering and plant construction, power stations, mining, environmental technology, chemical and petrochemical, on shore & off shore.
