Triple Offset Butterfly Valves – Hobbs Valves

Product Overview

Triple Offset Butterfly Valves from Hobbs Valves provide an unrivalled zero-leakage solution that provides high flow control performance compared to other butterfly valves. Hobbs Triple Offset Butterfly Valves are simple to maintain with lower cost of ownership and spare part replacements available.

Hobbs Valves have revolutionised Triple Offset Butterfly Valve design by enhancing additional operational features which allow for a more simplified manufacturing process.

The patented range is known as the Hobbs TVT range (Tomorrows Valve Today) that is able to provide superior performance zero leakage bi-directional triple offset butterfly valves, suitable for extreme pressure/temperature applications typified by the oil and gas industry.

The range of valves is available in a wide range of materials from high specification metals including carbon, stainless steel, high tensile or corrosion resistant aluminium bronze, 6 moly, titanium, duplex and super duplex.
