Advantages Of Wafer Butterfly Valves

The flowing medium can travel through a stream-lined butterfly disc without experiencing a significant pressure reduction or flow restriction.
Butterfly wafer valves are quick-acting; to switch the valve from the completely open to the entirely closed position, the stem only needs to be moved 90 degrees (1/4 turn).
The butterfly wafer valve design is well adapted for flow regulation and does not produce much turbulent flow when somewhat opened or shut down.
The butterfly wafer valves are better appropriate for larger applications since they are often less expensive and not heavier.

Wafer Butterfly Valves

Definition and Design

Wafer butterfly valves are designed to fit snugly between two pipe flanges. They are secured in place by bolts that run through the flanges and across the valve body. Unlike other types, wafer butterfly valves do not have their own bolt holes; They rely on the flange bolts to keep them in position.

How They Work

When the handle or actuator turns the shaft, the disc pivots to either allow or restrict fluid flow. In the open position, the disc is parallel to the flow, permitting passage with minimal resistance. In the closed position, the disc is perpendicular, blocking the flow entirely.

Parts Of A Wafer Butterfly Valve

01/

Valve Body
The bodies of butterfly valves typically slide between two pipe flanges. There are no lugs that stick out from the wafer body. The pipe flanges and the wafer valve are sandwiched together, and the body is encircled by the flange bolts. Compared to the lug-style butterfly valves, the wafer style is more affordable. Wafer designs prevent the weight of the pipe system from passing through the valve body directly.

02/

Seat
Different elastomers or polymers are utilized to create a butterfly valve’s seat, which is bonded to the body, squeezed, or locked up. Along the inner diameter of the valve, the seat is located. The flow is stopped when the disc presses against the seat and they seal. In the original design of these valves, the metal disc rested on the metal body, which did not produce a secure, leak-free seal. The inclusion of elastomers or polymers in the valve design will assist in providing a leak-proof and tight seal.

03/

Disk
A disc inside the industrial wafer butterfly valves regulates the flow of media via the valve. The concentric or eccentric disc can be used for the valve. The concentric disc is the less complicated among these two. The stem in the concentric design cuts through the disk’s centerline. Low-pressure applications frequently employ concentric valves. ncrete walls;.

04/

Stem
The butterfly valve’s stem can have a one-piece shaft or two-piece construction. In most resilient seated designs, the stem is shielded from the media, permitting for an effective material choice in terms of price and mechanical attributes.

05/

Hand Lever
Typically made of steel, these components undergo chemical treatment, powder coating, and salt spray testing to ensure dimensional precision. A handle and a locking lever are frequently found on hand levers. Additionally, they are typically employed for tiny valves. The sealed, open, and partly open states of these hand levers can all be secured.

06/

Gear
The gear is yet another component on the list of wafer butterfly valve parts for manually operated ones. For larger butterfly valves, these parts are employed. Utilizing a gearbox boosts the torque but reduces the pace of opening and shutting down. The gear-based wafer butterfly valves are self-locking and irreversible. However, they might retain positional cues.

Wafer Butterfly Valve Connection Method

Most wafer butterfly valves are designed with four alignment holes that match the pipeline flanges. These holes help position the valve correctly during installation. The valve is then clamped between two pipeline flanges and secured using double-headed bolts, ensuring a stable and leak-proof connection. This design eliminates the need for additional flanges on the valve body, making it a lightweight and cost-effective solution for low to medium-pressure systems.

How Does a Wafer Butterfly Valve Work?

At its core, the wafer butterfly valve’s operation is simple yet highly effective. Its working mechanism can be broken down into three main modes: open, throttling, and closed.

Open Position

When fully open, the disc rotates so it aligns parallel to the direction of the fluid flow. This streamlined position presents minimal resistance, allowing fluid to pass through almost unobstructed. Compared to other valve types, such as gate or globe valves, butterfly valves create less head loss due to their short face-to-face dimension and efficient disc design.

Closed Position

To shut off flow, the actuator or handle turns the stem, rotating the disc 90 degrees until it sits perpendicular to the pipeline. The disc edge compresses tightly against the resilient seat, forming a reliable seal that stops fluid passage. This quick quarter-turn action enables fast isolation, making the wafer butterfly valve ideal for applications that demand frequent shut-off and opening cycles.

Throttling Position

While wafer butterfly valves are primarily designed for on/off service, they can also be used for throttling — Controlling the flow rate by partially opening or closing the disc. By adjusting the disc to various angles between fully open and closed, operators can fine-tune flow. However, it’s worth noting that compared to specialized throttling valves like globe valves, butterfly valves offer less precise flow control. Excessive throttling can also increase wear on the disc and seat, shortening valve life.
