Triple Offset Butterfly Valve Series 3000 Catalogue

Triple offset butterfly valve providing customers with professional valve solutions for rigorous working conditions.to meet customer requirements, has been providing corrosion resistant, low or high temperature resistant, abrasion resistant and special material valves suitable for various media. We work closely with the oil & gas, power generation, mining, chemical, food & beverage and marine industries, to anticipate their needs and exceed their expectations.

The triple offset butterfly valve was provides bidirectional zero leakage& high performance, flowing the new industry category using a technology not previously available with other quarter turn valves.

A strong commitment to maintaining and improving the quality of both product performance and customer service is inherent within our management policy.

Zero leakage means no visible leakage when tested at high pressure with water and low pressure with air according to existing international standards.

Bubble Zero Leakage:

Disc seal ring was achieved by torque force evenly loaded on disc laminated seal edge, which has function to assure zero leakage in both hydrostatic or air test per API 598.

Low Friction:

The valve uses a three-cam structure that means an angular cam is added to acommon metal hard seal bi-cam butterfly valve. This angular cam functions to have any point between the seal ring and the seat ring quickly separated off or contacted during the valve open and close action to leave a low fricion between the seal pairs,the sealing ring and seat relies on the coordination of sealing parts, so it has lower friction and excellent wear resistance when opening and closing,both the disc and the body seat are perfectly round,the disc doesn't touch the body-sealing surface until the valve is completely closed.so,it is low wear.

Renewable Seal:

The sealing ring can be respectively maintained and replaced after accidental damage, this replaceable Seal ring allows for a dependable tight seal and a longer service life.

Best Value for Money:

butterfly valves (TOBV) provide the highest quality and best value available in the control industry. The unique design of these valves provides rugged reliability and extremely easy maintenance in the field. So reduces the cost of our customers while delivering the best value, independent and internal tests have proven our superior service life capability, with bubble-tight shutoff through over 100,000 cycles.

Three Kinds of Seals Design:

Triple eccentric butterfly valves provide unidirectional laminated seal, bidirectional laminated seal&unidirectional soft seal to our customer

Offset 1

The shaft is placed behind the plane of the sealing surface to provide a continuous seat path.

Offset 2

The shaft is placed to one side of the pipe/valve centerline to allow the displacement of the seal from the seat during the 90° opening.

Offset 3

The seat and seal cone centerlines are inclined in respect to the pipe/valve centerline. This third offset completely eliminates rubbing.

In fact, our customers regularly replace existing gate, ball and globe valves achieving substantial reduction of space and weight, while benefitting immediately from lower installation costs.

Triple offset valves have been used extensively in all applications where positive isolation is required. The quarter turn design and extremely low running torque also allow for accurate flow and pressure control. With ourvalves true isolation and control capabilities can be combined in a single product against the usual need for two distinct valves.

A PREMIUM QUALITY VALVE THAT MINIMIZES YOUR COST OF OWNERSHIP

YOU WOULD NOT USUALLY ASSOCIATE A PREMIUM PRODUCT WITH COST SAVINGS. HOWEVER, THE REALITY IS QUITE DIFFERENT WITH FLOATING SEAT BI-DIRECTIONAL SEAL TRIPLE OFFSET BUTTERFLY VALVES.

So what happens when you install and start operating the valve? floating seat bi-directional seal triple offset valve is designed to be virtually maintenance free and does not require planned maintenance in most applications, providing extra cost savings across its lifecycle.

SAFELY REPLACE YOUR EXISTING VALVES WITH FLOATING SEAT BI-DIRECTIONAL SEAL TRIPLE OFFSET BUTTERFLY VALVE.

Replacing an existing valve can be a necessity but also a strategic choice. floating seat bi-directional seal triple offset valve’s bi-directional zero leakage and inherently fire safe design allows our customers to easily replace gate, ball and globe valves and, with our long face-to-face valves (designed in accordance to ASME B16.10), this operation can be carried out without the need of any piping modification.

Using valves can also contribute to reducing systemic failures thereby improving the overall Safety Integrity Level (SIL); in fact by using floating seat bi-directional seal triple offset valves with an appropriate actuator selection, it is possible to configure the product to assist the required protective function.
