 Monoflange Products > Monoflange Series



Monoflange Valves

The Hex Monoflange valves are used on Upstream Offshore/Onshore Gas and Oil production and initial processing installations. Typically used on gas gauge pressure instrument applications to minimize the size and weight of the pipe-valve assemblies used for primary and/or secondary isolation, vent and calibration.

Also used in downstream Oil and Gas Refining and Petrochemical production on flanged processes, primarily on light end gas applications.

Features & Benefits




One piece rugged construction mean less probability of corrosion and longer life
Large variety of standard and optional materials and outlet options, mean you can select the style you need right from the catalog
Hex was the first in the industry to utilize Non-Rotating Stem Tip (NRT) technology. When the stem tip contacts the seat, it stops rotating, preventing the cross scoring and eventual leaks that can occur with ball type stems
