Your FAQs About Triple Offset Butterfly Valves Answered

As the name suggests, double offset butterfly valves have two stems offset from the centre. A triple offset butterfly valve has three. Two of which are placed in a similar position to the double offset butterfly valve, while the third is the geometry of the seating surface. This creates a cone shape between the disc and seat. Triple offset valves are used in similar industries as double offset valves, except in more demanding applications. Double offset valves experience friction at the first 10° of opening and last 10° of closing. The third offset ensures the disc and seat are not in contact until the last 1° of closing, allowing virtually frictionless operation.

Difference Between Double Offset and Triple Offset Butterfly Valve

In recent years, metal-seated eccentric butterfly valves have competed with more traditional industrial valves like the globe and ball valves for critical applications. However, even though lots of people already know how a butterfly valve works, much of the confusion lies in how such eccentric valves differ and what applications are suitable for each.

In this article, you are going to walk through the differences between these two kinds of butterfly valves to guide you when choosing a suitable industrial valve for your application.

What is a Double Offset Butterfly Valve

The double eccentric offset butterfly valve can also be called the high-performance butterfly valve or double eccentric butterfly valve. This valve is suitable for thicker media that has a high pressure because its design does not allow too much contact with the disc and seat.

Double Offset Butterfly Advantages

The balance of this valve is in the stem placed behind the circular disc. It allows the disc to self-adjust to the center, ensuring tight sealing. Even when the valve is fully opened, the valve does not touch the soft seat, ensuring a longer service life.

What is a Triple Offset Butterfly Valve

Also known as the triple eccentric valve, the triple offset valve (TOV) has been around for more than 50 years. Initially designed to service water applications as a shutoff valve, TOV is now considered as a top choice for many critical process applications.

The industrial valve sector, especially China butterfly valve manufacturers, are looking into the flexibility of these valves as alternatives to expensive and bulkier ones already in the market. Recently, TOVs have been developed to deal with fugitive emissions control.

Triple Offset Butterfly Valve Advantages

As a butterfly valve, it also belongs to the quarter family. It is also lightweight and easy to operate. Installation is also a breeze since there is less pipe bracing needed. Replacement of seat rings is also easy as this valve is top-entry.

The triple offset butterfly valve has a low torque so there is no need to have larger valves. That being said, this means higher savings costs. This valve has zero leakage closure on both ends.

The introduction of soft seats increases the value of the valves. Aside from being fire-safe due to the metal seats underneath the soft ones, the valves can now self center because of the elastomeric seat material.

Difference between the Double Offset and Triple Offset Butterfly Valve

Description Double Offset Butterfly Valve Triple Offset Butterfly Valve Seat Material Soft Material Metal Seat Sensitivity to Pressure and Temperature Fluctuations Yes No Seat Friction Low Very Low Class Rating 600 600 Applications Process On/Off Throttling Critical and Severe Applications Seat Lifetime Long Very Long Fluide Services Clean Dirty Bubble Tight Off Yes Yes Pressure Drop Highest Highest Cost Moderate Highest

One of the main differences between these two butterfly valves is how they look. In the double offset butterfly valve, the two offsets of this kind of valve allow for easy opening yet retains its strong sealing power.

Configuration

The offset of the disc can be found in two areas:

Slightly on the right side of the valve centerline Slightly near the center of the valve body where the stem is attached to the disc.

The first offset offers continuous sealing whereas the second offset allows the valve to open with little friction, increasing its life service.

On the other hand, the triple offset butterfly valve is called as such because it has three offsets located in three different positions. These can be best understood if you check out the image below.

The center of the disc and seat In the centerline of the bore and attached to the stem The offset is in centerline of the valve where it becomes the axis of the seat cone angle.

The angled position of the disc in relation to the seats minimizes seat damage as well as preserve the integrity of the sealing surface. Additionally, it also reduces the chances of the valve sticking to the seats and it lowers operating torque.

Working Mechanism

As it is eccentric, the double offset butterfly valve disc moves away from the disc as it begins to open. To have an effective bubble-tight seal, this valve utilizes line pressure that acts against the disc.

The triple offset type does not act like a typical butterfly valve which, with a turn of a lever, moves sideways to allow entry of media, like a waving of a hand. The triple offset type acts like a globe valve where the disc moves somewhat like a cone, moving upwards to downwards.

When the cone moves to become a circle, a tight seal happens. There is no drag when the seat takes contact with the disc because of the angled alignment of the disc in relation to the seat.
