Swagelok® Tank Blanketing Pressure Regulators

Tank blanketing regulators are designed to meet unique application needs.

Request More Information

Tank blanketing is when a gas is applied to the empty space inside a storage tank, regardless of tank size. The process typically involves using a buffer gas to protect products inside the storage container and can help improve tank usage life, safety, and equipment life cycle.

Swagelok® tank blanketing pressure regulators can sense a decrease in tank pressure. The regulator opens to introduce more gas until the vapor pressure in the tank reaches desired levels. When the pressure begins to exceed set levels, the regulator will close, allowing the pressure to stabilize.
