Tandem / Custom Valve Solutions
Application-Specific Multi-Valve Engineering
The Acuflow capabilities brochure describes Carten tandem valves as customized solutions in which an access valve is typically welded to a main valve to create GMP or SAP configurations. These are engineered to improve drainability and minimize dead legs. Carten’s current website supports a broader engineer-to-order approach but does not provide a dedicated public Tandem Valve product page.
Features
- Application-specific configuration
- Designed to improve drainability
- Designed to minimize dead legs
- Welded access-valve / main-valve configurations
- GMP or SAP configurations
- Full material certification
- Can be developed within Carten’s broader custom block / multiport engineering approach

- Line sizes from 1/16 in ID to 1 in ID on the current product page
- Integrated lockout feature with safety guard
- Interchangeable tubing holders for line-size changeout
- Reusable stainless-steel valve body
- Pneumatic or manual options across the Omnia family
- Automation, position sensing and solenoid options
- Designed for upstream, downstream and fill-finish single-use applications
Technical Specifications

- Downstream
- Fill-finish
- PUPSIT
- Sampling
- Fluid transfer
- High-pressure pump shut-off
- Applications requiring line-size interchangeability
Omnia Manual Pinch Valves
Manual Single-Use Flow Control
The patented manual pinch valve series works with multiple tubing brands and flow kits, including reinforced tubing, and allows on-site tubing-size changes through interchangeable insert kits.
Features
- For use with all tubing brands
- Available from 1/16 in ID to 1 in ID
- On-site retrofit using interchangeable insert kits
- Two footprints: BP25 and BP50
- Reusable stainless-steel valve assembly
