Introduction
Industrial piping systems require compact and dependable valves for manual isolation and flow management without adding excessive weight or installation length.
The TOYO VALVE 550LA Butterfly Valve, model 10ALM-N-LU<Z0T01>, combines an aluminum-alloy wafer body, SUS304 stainless-steel disc, NBR seat, and manual lever operation.
Its compact configuration supports installation between compatible piping flanges in building services, industrial utilities, water circulation, and general process applications.
Compact Wafer-Type Configuration
The wafer body is installed between two pipeline flanges, reducing overall size and weight compared with many conventional flanged-valve configurations.
The manual lever provides direct quarter-turn operation for visual confirmation of the valve position. Its center-drive disc configuration supports straightforward operation in applications requiring manual isolation or flow adjustment.
Final suitability must be confirmed according to the fluid, operating pressure, temperature, frequency of operation, piping standard, and required sealing performance.

Industrial Applications
The TOYO VALVE 550LA may be evaluated for:
Industrial water circulation
Building utility systems
HVAC and cooling-water piping
General manufacturing facilities
Equipment auxiliary piping
Industrial maintenance and replacement projects
Fluid compatibility must be confirmed specifically for the NBR seat, SUS304 disc, aluminum body, and actual operating temperature.
Information Required for Selection: TOYO VALVE 550LA butterfly valve
A technical inquiry should include:
Complete product code and model
Nominal valve size
Fluid and concentration
Operating and design pressure
Operating and design temperature
Required flange standard
Installation position
Required sealing performance
Existing drawing or valve nameplate
Required quantity
For replacement projects, connection size alone is insufficient. Face-to-face dimensions, flange compatibility, seat material, disc material, operating conditions, and available handle clearance must also be verified.
