BONT-WVE ball valves

BONT-WVE (former Williams Valve Engineering) is a trade mark owned by CESARE BONETTI Company, used to identify one specific ball valves production line.
In the year 2005 CESARE BONETTI S.p.A. purchased all design, know-how, manufacturing lines, sales and business activities concerning BONT-WVE ball valves.
All facilities and relate activities have been moved to the Garbagnate Milanese factory.

BONT-WVE ball valves meet highest technological and qualitative requirements of power industry, of chemical & petrochemical industry, as well of any other kind of industry that manages fluids.

BONT-WVE valves comply with main international standards as ISO, API, ASME, ASTM, B.S., DIN, etc., and particularly BS 5351, API 607, API 6D & API 6A.
The whole range is “Fire-safe” tested and certified according to API 6FA, API 607 and B.S. 6755 Part II specifications. On request CE certification can be released.

MAIN FEATURES
BONT-WVE ball valve range includes both “floating” as “trunnion” mounted valves. Valves can be equipped with “soft” seats as well as with metal to metal seats.
BONT-WVE ball valves are designed to withstand high pressure and both high or low temperature (cryogenic application).
Other specialties are valves for submarine application.
Finally, we can manufacture special ball valves, according to Customers’ specification or requirement.
The standard “trunnion” valves are equipped and supplied with “Self-Relieving” seats (SRE), having “Single Piston Effect” and “Single Bock & Bleed”, but on request “Double Piston Effect” (DPE) seats can be fit on valves, so granting “Double Block & Bleed” to the valve.
Also a combination of both type of seats can be fitted on the valves (SRE one side and DPE the other side).
All BONT-WVE ball valves incorporate one ore more antistatic device to ensure electrical conductance continuity between all metallic parts.
Other optional features include emergency sealant injection on stem and seats, transition rings or pipe pups (BW ends only), manual gearbox, electric, pneumatic, hydraulic, gas over oil or other means of actuation, locking and interlocking devices and other special accessories on request.
