In the field of flow control systems, precision, durability, and efficiency are key. Speciality Valve is a in to the group of trusted triple offset butterfly valve manufacturers in India, which also happens to present a great choice of industrial valves for severe service conditions. Triple offset butterfly valves (TOBV) are very much in demand in sectors like oil and gas, petrochemicals, power generation, water treatment, and marine, which require tight shut off, zero leak, and long service life.

What is a Triple Offset Butterfly Valve?

A triple offset butterfly valve is a type of butterfly valve that has improved upon the classic design by reducing seat wear out and also achieving a much tighter seal. Also, in contrast to concentric and double offset butterfly valves, which do not have this feature, the triple offset design includes an element of angular offset, which does not allow the seal elements (disc and seat) to touch until the valve is fully closed.

This design, which does away with friction, also which in turn reduces torque requirements and, at the same time, increases valve life. In what may be called a feature of this particular design, triple offset valves are also known to function as zero-leakage valves and metal-seated shut-off valves.

How Does a Triple Offset Butterfly Valve Work?

The triple offset butterfly valve’s function is based on its triple eccentric design:

1. First Out of Place: The shaft does not align with the disc centerline.
2. Second Shift: The shaft is out of alignment with the valve centerline.
3. Third Offset: We create a conical seating surface for uniform engagement of sealing surfaces.

When the valve is actuated, the disc turns without contact at the valve seat until final closure. This which in turn, eliminates seat wear, reduces operating torque, and provides a very tight seal for high-pressure and high-temperature conditions.

Where is a Triple Offset Butterfly Valve Used?

Triple-action butterfly valves are used in fields that require bubble-tight shutoff and fire-safe performance.

• The oil and Gas industry, which is used in refineries, pipelines, and offshore platforms for hydrocarbons.
• For steam isolation and cooling in Power Plants.
• In the Marine industry, which includes shipbuilding, we use seawater for fuel handling and seawater.
• Chemical Engineering, which includes the processing of corrosive fluids and high-temperature chemicals.
• Water and Wastewater Treatment for all your critical flow control issues.

Triple Offset Butterfly Valve Vs Double Offset

While both double offset and triple offset valves aim to reduce friction and extend lifespan, they differ significantly:

Thus, for critical industries, the triple offset design is preferred over the double offset.

Triple Offset Butterfly Valve Advantages

Selecting a triple offset butterfly valve also does:

1. Zero leakage bubble-tight seal, which is perfect for critical shut-off.
2. Extended Wear: No rubbing during operation reduces wear and tear.
3. Metal construction in all seats for safe performance in emergencies.
4. Bidirectional Sealing For use in either flow direction.
5. Reduced Torque Input: Easy automation with electric and pneumatic actuators.
6. Wide variety of sizes we offer butterfly valve, lug type, and flanged ends.

Types of Triple Offset Butterfly Valves

A triple range of butterfly valves is available, which is designed for various industries:

• Wafer Style Triple Offset Valve. Compact design for in-between flange installation.
• Lug Type Off-Set Valve is used for better alignment and in the case of dead-end service.
• Flange-ended Triple Offset Valve for heavy-duty use in high-pressure applications.

Components of Triple Offset Butterfly Valve

A typical triple offset butterfly valve includes:

1. Body of cast steel, stainless steel, or alloy steel.
2. Disc - Precision-machined for tight shut-off.
3. Seat Metal to metal seal, which is typically of stainless steel or Inconel.
4. Stem/Shaft Transmits torque, which in turn operates the disc.
5. Bearings Seals For smooth operation and leak prevention.
6. Actuator Types manual: gear operated, electric, pneumatic.

Industrial Applications of Triple Offset Butterfly Valves

1. Oil and gas pipelines
2. LNG and cryogenic services
3. Power plant steam isolation
4. Petrochemical processing units
5. Water distribution networks
6. Shipbuilding and offshore platforms

One Specific Industry Use – Oil Gas Sector

In the energy sector, triple offset butterfly valves are a key component in the processing of hydrocarbons at high pressure and temperature. For example, in refinery shutdown systems, which are critical, these valves provide zero leak isolation for safety. Also, they have a fire safe design, which, in addition to withstanding corrosive gases and fluids, makes them the preferred choice over ball valves or gate valves in critical service.
