In the field of flow control systems, precision, durability, and efficiency are key. Speciality Valve is a part of 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 which 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 out as 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:
- First Out of Place: The shaft does not align with the disc centerline.
- Second Shift: The shaft is out of alignment with the valve centerline.
- 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 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 shut-off 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 it for fuel handling.
- 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:
Feature
Double Offset Butterfly Valve
Triple Offset Butterfly Valve
Design
Two offsets from the disc and the shaft
Three offsets, including conical sealing
Sealing
Resilient or metal seat
Metal-to-metal seat, bubble-tight
Applications
General industrial use
Severe service, high temp & pressure
Leakage Prevention
Low to moderate
Zero leakage (Class VI shut-off)
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:
- Zero leakage bubble-tight seal, which is perfect for critical shut-off.
- Extended Wear. No rubbing during operation reduces wear and tear.
- Metal construction in all seats for safe performance in emergencies.
- Bidirectional Sealing For use in either flow direction.
- Reduced Torque Input: Easy automation with electric and pneumatic actuators.
- Wide variety of sizes we offer butterfly valve, lug type and flanged ends.
Types of Triple Offset Butterfly Valves
Triple range of butterfly valves is available which are designed for various industries:
- Wafer Style Triple Offset Valve Compact design for in between flange installation.
- Lug Type Off Set Valve which 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:
- Body of cast steel, stainless steel, or alloy steel.
- Disc - Precision-machined for tight shut-off.
- Seat Metal to metal seal which is typically of stainless steel or Inconel.
- Stem/Shaft Transmits torque which in turn operates the disc.
- Bearings Seals For smooth operation and leak prevention.
- Actuator Types manual, gear operated, electric, pneumatic.
Industrial Applications of Triple Offset Butterfly Valves
- Oil and gas pipelines
- LNG and cryogenic services
- Power plant steam isolation
- Petrochemical processing units
- Water distribution networks
- 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 temp. For example in refinery shut down 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.
