Butterfly Valves

Pure drinking water supply is crucial to the overall well being of society. For supplying potable, hygienic water to the industries and households, the water supply network has to be reliable, clean and manageable. Potable water butterfly valves are quarter turn rotary motion valves which are used to control flow of liquid through pipes. They offer several advantages like quarter-turn and good control capabilities. They have small dimensions and thus they can be used where space is a constraint, and they allow a good coefficient of flow.

We at Dutco Tennant LLC have deep expertise in supplying reliable, safe, and durable high performance Butterfly valves for the potable water supply network in the Middle East and GCC region. Our products are vulcanized with drinking water approved compound, well coated with accepted materials for durability and smooth performance. These products are DEWA, SEWA, and FEWA compliant.

The potable water butterfly valves that we offer have ductile iron body with EDPM rubber seats and stainless steel or nylon coated discs of all size. The products of all other materials such as Steel and Copper are also available. Iron and copper find wide applications in the potable water systems. Ductile iron is usually used in utility systems and copper in home and office plumbing
