About us
Wenzhou EAA Electric Co., Ltd
A manufacturer of precision pneumatic and electro-pneumatic automatic control products for automated industrial equipment, process control systems and valve automation — a subsidiary of Snda Industry Co., Limited.
What we build
Electro-pneumatic positioners and valve positioners in four installed patterns: the YTC YT-1000L and YT-1000R, the Rotork YTC new-type YT1000 series, the SMC IP8000 and IP8100 series and Metso's Neles NE700 and NE724 series. Alongside them: pneumatic valve actuators, limit switch boxes, pilot valves, and current and voltage transformers.
How we work
The company's stated aim is to remain a technological leader in Asia's automation instrument industry through quality assurance programmes and investment in advanced machine tooling. Production and inventory management, just-in-time manufacturing and computer tracking of inventory, production and customer orders are what make short-notice OEM runs possible.
OEM is the core business
Most of what leaves this plant carries a customer's brand. The OEM case gallery is the published record: colour runs in black, blue and yellow, IP8000 and IP8100 batches, NE724 batches, limit-switch orders and Rotork YTC new-module builds.
Inside the plant
Photographs published by the factory of the workshop, the benches where positioners are assembled and tested, and visitors being walked through production.
Certifications, headcount, annual capacity and export-market figures are not published on the source site and are therefore not claimed here. They are available from the factory on request.
The ranges we manufacture
YTC Type Valve Positioner
The YT-1000 family — linear YT-1000L and rotary YT-1000R — in every colour and accessory combination this factory builds, including the assembled positioner + PTM + limit switch stacks.
Rotork Type Valve Positioner
Positioners built to the Rotork YTC mounting and function pattern, including the new-generation module with automatic zero, span and friction detection.
NE700 Type Valve Positioner
Neles-pattern NE-series proportional positioners for cylinder or diaphragm actuators, rotary or linear, in vibrating service.
SMC Type Valve Positioner
IP8000 lever-type and IP8100 rotary-type electro-pneumatic positioners on the SMC pattern, interchangeable with the IP6#00 series.
Pneumatic Valve Actuator
Rack-and-pinion pneumatic actuators supplied on their own or as a complete assembly with positioner and switch box.
Limit Switch as Accessory
Five switch boxes — 210, 310, 410A, 410B and 510 — from plain indoor boxes to Exd II CT6 with IP67, PTM and solenoid valve options.
Pilot Valve as Accessory
Pilot valves for the positioner range — the air stage that sets dynamic response.
