Working Principle
|
Control Type |
Manual 3-way valve or Optional Electric Solenoid Valve |
| Working Mechanism |
Filling and emptying of the diaphragm with the system's own pressure |
|
| Solenoid Modes |
Normally Open (NO) or Normally Closed (NC) (Positive/Negative control) |
|
| Speed Adjustment |
Closing speed can be adjusted with a one-way flow restrictor (During ordering) |

Structural Features
|
Basic Parts |
Body, Cover and Diaphragm |
| Diaphragm Design |
"Springless" design (Distributes pressure evenly, prevents deformation, long-lasting) |
|
| Closing Characteristic |
Gradual closing (Prevents water hammer) |
|
| Maintenance |
Contains minimum moving parts, practically maintenance-free |
|
| Performance |
Precise regulation at low flow rates, full opening at low pressure (Low head loss) |
