Diaphragm Valves Custom Valve Solutions Fabricated Tandem

Tandem Valves (Sterile Access Valves)
Tandem valves are designed to optimize drainability and meet process design requirements for minimum dead legs. A main valve is ported and a second access valve is welded to the main valve to create a tandem cluster.

Custom Valve Solutions
Custom valve types may be welded tandem valve assemblies, machined from solid block types or manifolds that incorporate both technologies.

Custom Valve Solutions Benefits:
1. Reduced wetted area to reduced dead legs
2. Improved drainability and reduced design envelope over arrangements using individual 2-way valve bodies
3. Machined from solid bodies also offer increased security due to the elimination of internal fabrication
welds.

Valve Manifold / Clusters
Configuration of optimum process fabrication presents system designers with an ongoing challenge. Minimum space envelope, reduced hold up areas, reduced cost, and facilitating ease of installation are all key considerations.

Optimum Process Fabrication Benefits:
1. Tailor-made solutions to customer requirements
2. Fully-tested assembled units manufactured under controlled conditions
3. Full traceability of all components
4. Reduced on-site fabrication time and costs

Machined Tandem Valves
The Machined Tandem is a variation of the Serial Weir family.
This machined from solid Tandem Valve type offers several advantages over the welded tandem:

Machined Tanden Valve Benefits:
1. Increased security – no internal fabrication welds
2. Reduced dead leg – depending on orientation
3. Greater structural integrity
