Hillside, IL - Shand & Jurs is proud to announce improvements to its hugely successful 94270 Tank Blanketing Valve.
The 94270 Tank Blanketing Valve now incorporates a new internal Teflon® O-ring coating which improves the performance of the unit and reduces maintenance time and costs.
This new Teflon® coating is now part of Shand & Jurs' standard offering for our ½ inch, one inch and two inch Tank Blanketing Valves. The 94270 is also available with accessories including filters, check valves and pressure gauges.
"Tank Blanketing" is a process used to maintain a gas barrier in the vapor space of a pressure-tight storage tank. It prevents evaporation, reduces emissions, corrosion, contamination or oxidation and provides gas make-up when internal tank pressure drops. The S&J 94270 Tank Blanketing Valve provides primary vacuum relief by controlling the flow of blanketing gas into the tank during product movement out of the tank.
The 94270 has a balanced piston-operated main valve so that the set point pressure is virtually unchanged at any given inlet pressure within the specified operating range. The "VAPOR GUARD" has a modulating type action valve that opens and closes automatically, maintaining a closely controlled blanket pressure and gas flow. The modulating action simplifies the valve design, thus increasing reliability and reducing maintenance costs. The "VAPOR GUARD" operates in the closed position whenever the tank pressure is satisfied or exceeds the set pressure. Whenever the sensed pressure decreases, the set pressure spring and diaphragm assembly causes a downward force such that the main valve will open proportionately to control pressure and limited capacity. The one and two inch models have a minimum inlet pressure of 30PSI, while the half inch model has a minimum inlet pressure of 20PSI.
