SPRING OPERATED TANK BLANKETING VALVE

SPRING OPERATED TANK BLANKETING VALVE - 1/2"

Series No. 30

Protectoseal Series No. 30, Spring Operated Tank Blanketing Valve, is designed to regulate the flow of a blanketing gas (usually Nitrogen) into the vapor space of a flammable liquid storage tank or vessel. The Series No. 30 valve is spring operated. The pressure balanced poppet is held in its closed position by direct spring force. The tank's vapor space pressure is sensed in the diaphragm case and the valve opens to allow a flow of gas into the tank when the pressure drops below its set point. When tank pressure returns to an acceptable level, the flow of gas is stopped.

The pressure balanced valve poppet ensures that a consistent opening set pressure is realized over the range of allowable inert gas supply pressures. The Series No. 30 valve is suitable for use on smaller tanks and vessels. Standard 1/2" NPT inlet and outlet connections are provided.
