DOROT S100 FLDI/SP

Weir-type Diaphragm, Differential Float Level Control, Globe Valve, with anti-surge closure

DOROT S100 FLDI/SP, is a Weir-type Diaphragm, Differential Float Level Control, Globe Valve, with anti-surge closure. The valve opens when the water level reaches a set opening height, and closes at a set lower/higher level. The valve controls water levels within a desired range and is unaffected by flow rate or pressure changes. The differential between opening and closing levels is adjustable. Closure velocity is automatically and dynamically self-adjusted to prevent surge. (an optional surge protection device can also be added to any control function).
