Set for TWIN uninterrupted operation systems with 1.5″ control valves

Article : VLV15BSPT
  • Used to construct TWIN systems  ?
  • Simplicity of design 
  • Connection without microswitch  ?
  • Does not create water hammer 
  • Long service life  ?

The set is intended to redirect the supply of flows of feed or purified water during regeneration of the purification system.  

It is applied in all the backfill filters with CE15″ reagent control valves. Used in manufacture of the TWIN systems.

Key advantages:

  • easy and convenient to install at the control valve;

  • simple design, long and reliable operation;

  • does not burn out;

  • connected without microswitch;

  • does not create water hammers.


Device and system operation

In TWIN uninterrupted operation systems, the two filter columns work in rotation.

To ensure an uninterrupted supply of purified water to the consumer, an automatic three-way valve with a servo-actuator is installed on the output line. The valve is connected to a special connector of the filter control valve. At the moment of the the beginning of the regeneration of one of the filters, the control valve signals the three-way valve to shut off the flow of water after the filter, which is regenerated, thereby blocking the access of untreated water to the consumer, and opens the flow of purified water to the filter that started filtration.

In the TWIN uninterrupted operation systems two filters work alternatively.

To guarantee uninterrupted supply of purified water to consumer, MAV (motorized alternating valve) is installed at the permeate outlet of control valve. The MAV is connected with the cable to the special connector of the filter’s control valve. In the beginning of the regeneration of one of the filters the control valve sends a signal to the alternating valve to cut the water flow after the filter that is being regenerated. By this it blocks access of unpurified water to consumer, and supplies the flow of purified water from the filter that has started filtration.  

The set requires regular maintenance which involves disassembling and thorough cleaning of the flow distributor and other elements of the alternating valve. 


The service should be performed by qualified staff.
