Triple offset butterfly valve

Compared to gate, globe or ball valves of the same size and pressure class, Tri Lok provides space and weight savings while minimizing installation and maintenance costs. Tri Lok is a premier isolation valve , well suited for operation in light vacuum to high-pressure applications. Each offset valve has functionality and benefits of their own.

With the triple offset butterfly valve there are three offsets. Two are placed in a similar position to the double offset butterfly valve , while the third offset is the geometry of the seating surface, creating a type of cone shape of the disc and seat. This cone angle, along with the two eccentric shaft offsets. Since their introduction to the market more than years ago, triple offset valves (TOVs), which are also known as triple eccentric valves , have continued to evolve, while uses for this type of valve have expanded across multiple industries.

The diameter of these valves range from a few inches to a few feet because they are used in a variety of situations. There are different kinds of butterfly valves that have been modified for different fluids, pressures and usages. BM Engineering’s guide to triple offset butterfly.

The principal balance is the pole that is spotted not in the middle of the plate yet found on somewhat behind the circle.

Only Flowserve replacement repair parts should be used. What is a triple eccentric butterfly valve? The seat of the triple offset valve is designed to minimize wear, provide lower maintenance cost and extend service life. The ‘zero leakage’ sealing capabilities of triple offset valves provides the performance to keep your processes operating reliably at top efficiency even in extreme operating conditions.

Limited takes great care to engineer the interiors and exteriors of the valve. Butterfly valves must, at all times, be of top-notch quality. Our triple offset valve , also known in the industry as triple eccentric or triple offset butterfly valve , represents an important step forward compared to traditional process valves , such as gate, ball, globe and plug valves. There are now over 300Vanessa valves operating around the world. While offering equal performance to the others, the Hobbs Valve clearly occupies far less space.

These valves are well suited for operation in light vacuum to high pressure applications. The standar non-rubbing, metal-to-metal sealing system is inherently fire safe by design. Triple offset butterfly valve can be used not only on-off but also regulating the flow. CRYOGENIC TRIPLE OFFSET BUTTERFLY VALVES. The Maverick butterfly valve for cryogenic service is designed for tight shut off and throttling service.

This eliminates concentrated wear points on the sealing ring and extends it’s lifetime. Standard body patterns are flanged and butt welded types. The WKM triple offset valve (TOV) completes Cameron’s reliable, performance-proven, quarter-turn butterfly valve portfolio.

The true triple offset geometry of this valve allows for bubble-tight sealing to create a fully bi-directional zero-leakage shut-off valve. Tripple offset , piece shaft design. Neldisc triple eccentric disc valves operate both in control and shut-off.
