Long Description
The VIATRAN AT-1000 LPG Freeze Valve was developed and calibrated to establish the presence or absence of moisture in propane type liquefied petroleum gases by the Valve Freeze Method. The Valve Freeze Method was published for information only by the American Society for Testing Materials in the “ASTM 1963 Standards-Volume 18”. The use of this valve and test method provides a relative measure of the tendency of propane type liquefied petroleum gases containing moisture to freeze in pressure reducing regulators and thereby interrupt the normal flow of gas. The test method is applicable to all propane type LP gases including those that contain certain anti-freeze agents.
