Dorot Series 100 The direct sealing diaphragm valves were introduced to the world market for the first time by DOROT CONTROL VALVES at 1982. This valve is operated by the pressure of the pipeline and is used for various control applications in water supply, fire fighting, industrial, sewage and irrigation systems. The only moving component is a reinforced diaphragm, which: a. Drip tight seals the liquid passage in the closed valve b. Allows free passage in the fully open valve with minimal obstruction to the flow line c. Throttles the flow passage in the modulating valve, as dictated by the pressure...

Principle of operation 3-way control system The main valve is controlled by a manually, electrically or pressure actuated selector that: 1 Introduces the upstream pressure or an external pressure source to the valve’s control chamber, thus pressing the valve diaphragm from top to a closed position. 2 Openes the valve by relieving the pressure from the control chamber and enabling the internal pressure in the line to push the valve diaphragm up and creating an unrestricted, full flow passage. 3 Shutes all passages to and from the control chamber, thus keeping the main valve in a fixed position....

Control Functions M Manually Controlled Valve Description The valve is controlled manually by a three port selector that allows the user to select the closed, opened or remotecontrolled position of the valve. The control is effected effortlessly and quickly, even under high pressure conditions • Effortless open/close activation • Fast response • Clog-free operation • Can be added as manual over-ride to any other control Main Valve Self-flushing filter Cock valve* 3-way selector valve Accelerator relay (optional for valves larger than 150mm/6”) * Optional component Purchase Specifications The...

Control Functions EL Solenoid Controlled Valve Description A 3-way solenoid valve, activated by an electric current or an electric pulse, opens or closes the main valve. The standard valve is supplied in the “normally closed” position. The “normally open” position is optional. Electric activation can be added to other control applications on request. • Low power electric activation • Fast response • Simple and reliable design • Can be added as electric over-ride to any other control function Main Valve Self-flushing filter Cock valve* 3/2 Solenoid valve Accelerator relay (optional for valves...

Control Functions RC Hydraulic Remote Controlled Valve Remote pressure command Description A 3-way relay valve, activated by hydraulic or pneumatic pressure command, opens or closes the main valve. The standard valve is supplied in the “normally closed” position. The “normally open” position is optional. Hydraulic activation can be added to other control applications on request. • Fast response even for long control lines • Simple and reliable design • Can be added as pressure command over-ride other control function Main Valve Self-flushing filter Cock valve* Manual over-ride selector valve*...
