Honeywell HERMetic Deck Valve A-4-2-1 SS TS 98172

Honeywell HERMetic Deck Valve A-4-2-1 SS TS 98172


This valve has been specifically designed so that all the HERMetic equipment, with either 1”, 2”, or 4” connections, will be compatible.Organisations such as the American Petroleum Institute and the EnergyInstitute, recommend the size of the vapour valve to be 4” (100mm). The4” valve will allow access to a larger number of gauging and sampling equipment than ever before, depending on the product and sample type required. Vapour valves smaller than 100mm in diameter are suitable forgauging but can severely limit the type of sampling equipment that can beused and, ultimately, the quality of the sample. The size and location of thevapour valve for closed system measurement and sampling is critical tothe process. A valve of the proper size, located correctly, will allow moreaccurate measurements to be taken than one that is improperly located andof insufficient size. The new multi-purpose valve gives the flexibility to gaugeproducts from crude to chemicals. Most importantly, it will allow the use ofsampling equipment with the capabilities of retrieving sample quantities from0.33 litres to 1.8 litres in one single operation.

How Does It Work?
HERMetic valves are available in 1-inch, 2-inch and 4-inch sizes, depending on the equipment to be fitted on the valves. The top part of the valve is designed to support all HERMetic gauging and sampling equipment with a 1-inch, 2-inch or 4-inch connection.

What Problems Does It Solve?
Honeywell’s HERMetic valves are the interface between the tank and the gauging or sampling equipment. They ensure proper connection of the units and prevent any gas release from the tank during gauging and sampling operation.
