Plastic Butterfly Valve Handle Ball Knobs

Description

Plastic Butterfly Valve Handle Ball Knobs

These round plastic ball knobs are listed as butterfly-valve handle accessories. The product options include threaded balls in blue, black and red, plus two black through-hole styles. IKSONIC manufactures plastic butterfly-valve handle ball knobs in China for wholesale orders. Match the ball diameter and attachment specification to your existing handle before ordering.

Material and Option Overview

• Ball body: Plastic, as shown in the product information; the specific resin grade needs confirmation.
• Threaded versions: The internal thread material is described as copper. No precise copper alloy or purity is specified.
• Thread designations: M8, M10 and M12, depending on the color and diameter option. Thread pitch and engagement depth are not supplied by these designations alone.
• Threaded ball diameters: 31 mm and 39 mm, in the listed combinations below.
• Through-hole versions: Black 31 mm and 37 mm balls, with photo-labelled hole IDs of 9 mm and 11 mm respectively.
• Selection count: 13 product option labels, including two option labels that repeat black OD 31 mm / M10.

Specifications / Models

All 13 Product Option Labels

Each row preserves a product option in the range. Two invoice-only entries are omitted because they are commercial notes, not product variants. The two black OD 31 mm / M10 entries remain separate: both labels are listed but no distinguishing feature. The count is therefore 13 option labels, not a claim that all 13 describe different physical specifications.

Complete product-option list, retaining the repeated black 31 mm / M10 entry

No.	Color	Ball OD (mm)	Attachment style	Listed thread designation	Selection note
1	Blue	31	Threaded	M8	Thread pitch and engagement details require confirmation.
2	Blue	31	Threaded	M10	Thread pitch and engagement details require confirmation.
3	Blue	39	Threaded	M10	Thread pitch and engagement details require confirmation.
4	Blue	39	Threaded	M12	Thread pitch and engagement details require confirmation.
5	Black	31	Threaded	M10	Repeated black OD 31 mm / M10 specification retained as a separate listed option. No differentiating feature is stated.
6	Black	39	Threaded	M12	Thread pitch and engagement details require confirmation.
7	Black	31	Threaded	M8	Thread pitch and engagement details require confirmation.
8	Black	31	Threaded	M10	Repeated black OD 31 mm / M10 specification retained as a separate listed option. No differentiating feature is stated.
9	Black	31	Through-hole	Not specified for through-hole option	Photo 11 states hole ID 9 mm. A separate annotated span is unnamed; see the reference table.
10	Black	37	Through-hole	Not specified for through-hole option	Photo 10 states hole ID 11 mm. A separate annotated span is unnamed; see the reference table.
11	Red	31	Threaded	M8	Thread pitch and engagement details require confirmation.
12	Red	31	Threaded	M10	Thread pitch and engagement details require confirmation.
13	Red	39	Threaded	M12	Thread pitch and engagement details require confirmation.

The through-hole labels do not state a thread. Do not substitute a threaded ball for a through-hole option, or infer a threaded insert in the through-hole styles. For M8, M10 and M12 options, confirm the exact thread pitch, usable engagement and mating-handle requirements before ordering.

Two Through-Hole Photo References

The product photos explicitly identify the outer diameter and hole inner diameter shown below. Each also contains one additional dimension arrow without a formal feature name. Those spans are retained for completeness but are not assigned a counterbore, countersink, hex or other geometry interpretation.

Black through-hole ball references, all annotated values in mm

Photo reference	Ball OD	Hole ID	Additional unnamed span	Limit of interpretation
10	37	11	17	Feature and measurement basis not named; confirm separately.
11	31	9	14	Feature and measurement basis not named; confirm separately.

Photo 10 supports the black 37 mm through-hole option only; photo 11 supports the black 31 mm through-hole option only. Their hole IDs and unnamed spans must not be applied to the threaded versions.

Choosing a Replacement Handle Ball

1. Identify whether the existing handle uses a threaded attachment or a through-hole ball.
2. Measure the required outer diameter and select the listed color/size combination.
3. For a threaded attachment, confirm the M designation, pitch, engagement depth and mating component dimensions. Do not assume pitch from diameter alone.
4. For a through-hole attachment, confirm the hole size and any other locating or fastening geometry. Ask for clarification of the unnamed 14 mm or 17 mm span if it matters to fit.
5. Provide quantity, valve/handle identification and any required material or operating specifications for confirmation.

A matching color or outside diameter alone does not establish compatibility with a particular butterfly-valve handle. Confirm the required plastic resin, insert material, attachment details and any mechanical or application-specific requirements for the selected option.

Frequently Asked Questions

What is the internal thread material?

The product information describes the material as copper. It does not identify a particular alloy or purity. Confirm the required insert material if your specification needs a defined grade.

Does M10 specify the complete thread?

No thread pitch or engagement depth is supplied in these option labels. Quote the M designation together with the required pitch and fit details so the exact threaded connection can be confirmed.

Why is the black 31 mm / M10 option listed twice?

Two separate option labels describe that combination. They are retained rather than silently merged, but no distinguishing feature is established. Identify the intended option and ask for confirmation before ordering.

Are the through-hole options threaded?

These options are listed as through-hole balls and does not assign them a thread designation. Their photos state hole IDs of 9 mm for the 31 mm ball and 11 mm for the 37 mm ball. Any additional attachment details need confirmation.

What do the 14 mm and 17 mm arrows describe?

The illustration does not name the measured feature. They are shown as additional annotated spans only. Do not use them as confirmed counterbore, countersink or hex dimensions without clarification.

Do the photos establish fit or an application certification?

No. The product is presented as a butterfly-valve handle accessory, but the selected dimensions, material and application requirements still need to be checked for the particular handle.
