Valve Automation Accessories
-- Steady & Reliable Manufacturer --
Brief Product Description
Valve automation accessories are the mechanical add-on parts that complete an actuated valve package: mounting brackets, couplings, drive adapters, stem extensions, position indicators, stop bolts and protective covers. They are bought by actuator brands, valve assemblers, distributors and integrators who need fast delivery of small parts that fit well the first time.
Typical checks include bracket flatness and bolt pattern, coupling bore and keyway tolerance, thread standard, material and coating, and compatibility with ISO 5211 and DIN 3337 interfaces. Some buyers want accessories packed in kits by valve size so assembly teams do not need to sort parts.
We cast and machine the accessories ourselves, so one factory can supply brackets, couplings and indicators with matching quality. OEM and ODM support is available for custom bolt patterns and drive shapes. Samples usually take 7 to 20 days, and MOQ commonly starts at 100 to 300 pieces per item with mixed-size orders possible.
Small parts are counted, labeled and bagged by part number or packed in kits by valve size, which saves sorting time at your assembly bench. Gauge checks on bores and bolt patterns are part of routine inspection.

Product Overview
Valve automation accessories connect an actuator or gearbox to a valve and make the assembly usable in real plants. Brackets hold the actuator at the correct height, couplings transfer torque from the actuator output to the valve stem, and indicators and stops show and limit valve position.
A well-made accessory removes assembly guesswork. For example, a bracket machined with the right spigot and bolt pattern ensures the stem and actuator share the same center line, and a coupling with a proper keyway avoids backlash. Since accessories are small and varied, accurate drawings, clear part numbering and consistent coating are as important as the machining itself.
Interface
ISO 5211, DIN 3337
Materials
Aluminum, steel
Process
Casting and CNC
Supply
Single parts or kits
Main points for buyers
- Bolt pattern and spigot: Confirm the ISO 5211 pad, bolt circle and spigot diameter on valve and actuator.
- Bore and keyway: Specify stem size, key size and tolerance to avoid backlash.
- Material choice: Choose aluminum for light brackets or steel for high-torque couplings.
- Corrosion protection: Match anodizing, zinc plating or paint to the site.
- Kitting: Ask for kits by valve size to speed up your assembly line.
Price for accessories depends on material, machining time, number of holes and tolerances, plating or coating, kit packaging and quantity. Small batches of many different parts increase setup cost, so grouping part numbers can lower the unit price. When comparing offers, check whether fasteners, plating and labeled packaging are included.

Target Customers
Actuator Brands
Need brackets and couplings matched to their actuator series.
Valve Assemblers
Need accessories delivered as kits sorted by valve size.
Spare Parts Distributors
Need small parts with clear numbering and stable supply.
Suitable and Unsuitable Uses
Suitable Uses
- Automating existing quarter-turn valves
- Bracket and coupling sets in repeated sizes
- Retrofit projects that need custom adapters
- Light-duty to medium-duty torque transfer
Unsuitable Uses
- Torque that exceeds the coupling rating
- Heavy side loads on brackets not designed for them
- Temperatures outside the material limit
- Valves with unknown or damaged stem dimensions
Selection Guidance
Usage Notes
- Check center alignment of actuator and stem after mounting.
- Use the correct key and fasteners for the coupling.
- Apply thread locker where vibration is expected.
- Do not exceed the torque rating of the coupling.
- Inspect coating or plating on steel parts in humid areas.
Advantages
Matching quality across parts
Brackets, couplings and housings are machined in the same plant on 18 CNC lathes and 5 machining centers. Parts from one supplier fit together, reducing rework at your assembly bench.
Flexible batch sizes
Small and mixed orders are practical because casting and machining are in-house. You can stock a range of sizes without committing to large volumes.
Custom adapters
Engineers draw custom bolt patterns and drive shapes to your valve and actuator data. Retrofit projects can proceed without trial and error on site.
Even coating
Anodizing, powder coating and our 300-meter painting line deliver consistent appearance. Parts look uniform and resist corrosion during storage and service.
Clear identification
Part numbers or logos can be marked and parts packed in labeled kits. Your warehouse and assembly teams spend less time sorting.
Quality records
ISO 9001 procedures cover inspection and traceability. Documentation is available when your customers ask for proof.
Frequently Asked Questions
- Q: What accessories do you supply?
- A: We supply mounting brackets, couplings, drive adapters, stem extensions, position indicators, stop bolts and protective covers.
- Q: Can you make a custom bracket for our actuator?
- A: Yes. Send actuator and valve drawings, or samples, and we will propose a bracket design for approval.
- Q: What is the MOQ?
- A: MOQ is typically 100 to 300 pieces per item, and mixed sizes can often be combined.
- Q: Which materials can you use?
- A: Aluminum alloy is standard. Carbon steel and stainless steel are available for couplings and high-torque parts on request.
