Roche-Tech AU supplies and manufactures industrial valves for water, infrastructure, and process applications where reliability and durability matter. Our valve range is engineered to deliver dependable shut-off, flow control, and long service life across demanding operating environments.
We manufacture and supply gate valves, resilient seated valves, ball valves, and non-return valves for a broad range of industrial duties. Standard sizes are available up to 750 NB with pressure ratings up to PN25, and bespoke valves can be produced to match specific duty conditions and project requirements.
Our valve solutions are supported by robust engineering, controlled manufacturing, and quality verification procedures to ensure fit, function, and repeatable performance in service.

Standards and Compliance Capability
Roche-Tech AU can manufacture valves to suit applicable Australian and international project standards, subject to final design review, service conditions, and client specification. This includes support for common valve, flange, pressure class, and drilling requirements used across Australian industrial, water, and process applications.
Common Standards
- AS 2129 flange requirements for pipes, valves and fittings
- AS 4087 metallic flanges for waterworks purposes
- ASME B16.5 flanges and flanged fittings for NPS 1/2 to NPS 24
- ASME B16.47 large diameter flanges for NPS 26 to NPS 60
- API 6D for pipeline and piping valves where specified
- API 600 and API 598 for applicable valve design and testing requirements
Ratings and Drilling Patterns
- ASME / ANSI class ratings including Class 150, 300, 400, 600, 900, 1500 and 2500 where applicable
- AS 4087 pressure classes including PN 14, PN 16, PN 21 and PN 35
- AS 2129 table-based flange drilling to project specification
- Flange drilling patterns and facing details can be matched to client drawings and nominated standards
- Material traceability, dimensional inspection, and pressure / leak testing can be aligned with project QA requirements
If a project calls for a specific Australian Standard, ASME / ANSI class, API requirement, flange drilling pattern, or testing regime, valves can be engineered and manufactured to that nominated specification as part of the supply scope.
Why Choose Roche-Tech AU for Valves
