Large PRV High Pressure PRV Tank Valve Used in Power Transformers, these PRV operate at a predetermined pressure to neutralize the high pressure condition developed inside the tank. Used in Special Transformers, these PRV operate at extremely high pressure starting from 21 psi to neutralize the high-pressure condition developed inside the tank Tank/Air Valves are especially designed to permit quick inflation, deflation & gauging of containers with /without various standard equipment such as air chucks, deflators & pressure gauge. They provide minimum protrusion within the containers where space is at premium. Pressure Alarm System Solenoid Interlocking Device Oil Level Indicator The device raises an alarm if there are any gradually high or low pressure in the transformer tank while in transition or before mounting. Used mostly in dry transformers, substations a special castle lock and key arrangement to make sure a definite sequence of operations are performed. Available in various designs and mounting, oil level indicators are used to measure the oil level in the tanks and transformers. Small PRV Oil Level Indicator with PRV N2 Gas Regulator Ideal to be used in distribution and instrument transformers, these PRV operate at a predetermined pressure to neutralize the high-pressure condition developed inside the tank. Available in vertical mounting, this 2-in-1 device serves the purpose of both a PRV and Oil level Indicator This device is used to provide constant Air pressure/ dry Air pressure so that the atmospheric air and moisture does enter the transformer tank.
