SP - DYNAMIC CLOSURE-RATE CONTROL (END-LINE APPLICATION) - Series 300

SP - DYNAMIC CLOSURE-RATE CONTROL (END-LINE APPLICATION) - Series 300

A unique DOROT control module, that can be added to any automatic valve. It prevents water hammer, that is generated by the valve closure, when it is located at the end of a long pipeline
 
The "SP" feature is added to the standard control circuit of float valves, remote controlled electric valves, and other automatic valve applications. During valve closure, the valves senses upstream pressure.
When the pressure exceeds the static pressure at the valve location, the "SP" Device instantly stops the closing process. The closing procedure resumes when the pressure drops to normal. In case of excessive pressure, the device re-opens the valve, operating as a quick-relief valve.
The above mentioned process generates the“closing stages”, where the valve automatically adjusts its closure pace to meet the hydraulic characteristics of the network.

SP - DYNAMIC CLOSURE-RATE CONTROL (END-LINE APPLICATION) - Series 100

The device can be added to any control function and automatically adjusts the closing speed of a valve that is located at the end of a long pipeline. This ensures a moderate flow change pace that prevents pressure surges from evolving. Please consult DOROT for more details
 
  • Can be added to any fast closing control function 
  • Automatically self-adjusted closing pace 
  • Completely hydraulic – no electronic controllers, batteries or relays are used
  • Simple and reliable design

EL\TO -Two Stage Opening Solenoid Control Valve - Series 300

Dorot Series 300 Electric Control Valve (’30-EL\TO’) is an automatic, solenoid control valve, activated by the pressure of the pipeline. The valve controls by an electric current or an electric pulse, opens or closes the main valve. The ‘TO’ device prevents damage caused by too fast filling of a drained pipeline. The flow rate will be restricted, until the network, downstream of the valve is full and then a full opening of the valve is enabled.

*The ‘TO’ device can be added to any el control function

TO - TWO-STAGE OPENING - Series 100

The device can be added to any control function and will prevent damage caused by too fast filling of a drained pipeline. The flow rate will be restricted, until the network, downstream of the valve is full and than a full opening of the valve is enabled. Please consult DOROT for more details.
 
  • Can be added to any pipe-filling control function 
  • User adjusted filling pace
  • Completely hydraulic – no electronic controllers, batteries or relays are used
  • Simple and reliable design
