Variants
Type UK-V
3-way combination with bolted valves
Type UK-L
4-way combination with loose valves
All types of AZ-valves combinable with different valve types and sizes
To avoid misalignment of the plug-axis, in case of wrong assembling, we recommend the screwed design TYPE “UK-V” of our crossover-valvecombinations
Individual selection of the piping centreline dimension (RMA) minimum size = RMAmin)
Applications for
- exchange
- maintenance
- regeneration
of individual components without process interruption
Durable
- Sealing surfaces remain clean and do not come in contact with medium
- plug protection
- adjustable
- constant torque ( Δp independent !)
High economic efficiency
- maintenance without shutdown of production
- Operation with just one actuator
- simple & safe control
- uninterrupted parallel operation
Operating principle with 3-way and 4-way plugs
Service switchover
Examples of pump service
Cross-over valve combination with two 3-way valves for simple exchange or repairing of a pump without process interruption
Description
- System operation with pump
- break-down of pump
- switching to pump without interruption of the
continuous flow - replacement of pump
Same procedure with other plant components, e.g. filters etc.
Parallel operation switchover
Examples of air drying
Cross-over valve combination with two 4-way valves (with LL4 plug type) for purging or regeneration of components without process interruption
Description
- Drying plant for providing dry process air is saturated with water
- switching to plant without interruption of the continuous flow
- Regeneration of the drying plant and draining of condensates
