Why Choose the ATLAS Solenoid Valve Control Solution?
The ATLAS solenoid valve control solution uses the installation’s own water pressure to operate a diaphragm main valve. Filling or draining the control chamber produces valve movement. Manual three-way control or an optional electrically operated solenoid pilot can be selected for field operating requirements.
Normally open and normally closed solenoid options support the required control behaviour. A one-way flow restrictor supplied within the order scope can adjust closing speed, helping commissioning account for hydraulic conditions. It is not a guarantee of surge-free operation in every situation.
The technical table lists EN-GJS-400-15 main valve material, DN50–DN400 sizes and PN10/PN16 options for different water lines. The stated 2–40 °C range and selected pilot-circuit characteristics are checked against the application’s pressure, temperature and electrical control requirements.
Key benefits
- Diaphragm main valve control using system pressure.
- Manual control or optional solenoid pilot.
- Project-specific size, pressure rating and closing-speed selection.
