The NEOTECHKOREA Nitrogen Gas Blanketing Valves ensure that a constant gas pressure is maintained in the vapor space of storage tank. When liquid is removed from a tank or the temperature is reduced, a vacuum would be developed. With the blanket gas regulator, a blanket gas is supplied to prevent any vacuum from developing and to maintain the desired blanket pressure.
The Model NK-NB2L is a pilot-controlled stainless steel valve using a single oversized diaphragm actuator. The Model NK-NB2L is a direct–operated stainless steel valve using a single oversized diaphragm actuator. The oversized actuator offers high sensitivity to change in tank pressure, which increases the accuracy. The valves are fully balanced under all operating conditions, allowing for operation with varying inlet pressures. Blanketing pressure set point is easily controlled by a single adjusting screw.
