Dorot, part of Matholding Group, is a leading manufacturer of fire protection hydraulic control valves.

Dorot Fire Protection Valves provide a reliable and comprehensive solution for all fire protection applications: from basic fire suppression systems to the most demanding fire protection applications. Dorot’s Fire Protection systems can be utilized in hazardous offshore and onshore locations, and/or corrosive environments such as refineries, platforms, FPSO’s, power generation plants etc.

Dorot offers a variety of water, foam and seawater fire protection valves for use in deluge, Pre-Action systems, pressure regulating, water level control, hydrants and monitors.

Dorot valves are made from a variety of materials such as Nickel-Aluminum-Bronze, Stainless Steel, Super Duplex, Bronze / Marine Bronze, Cast Steel and Ductile Iron.

Standard material valves such as Ductile Iron (ASTM A-536 65-45-12) and Cast Steel (WCB A-216) are coated as standard with zinc-enriched, high-build fusion-bonded epoxy (FBE) and a UV protective topcoat conforming to EN12944 C4 & C5 high & very high corrosion protection grades. Naval quality very high corrosion protection grade conforming to EN12944 C5M is available upon request. Other coating standards such as NORSOK or ANSI/NACE as well as coatings for special material valves such as austenitic Stainless Steel (CF8M/ASTM A-316) and Nickel Aluminum Bronze (ASTM B-148) can be supplied upon request.

Water Level Control Valves

FLModulating Float Control Valve

The main valve is controlled by a float assembly, located in the tank or reservoir and set to the required maximum water level. The valve constantly maintains the maximum level.

Features:• Accurate level control• Simple and reliable design• Easy installation and maintenance• The application is based on the UL listed valves

FLELElectric Float Control Valve

The main valve is actuated by a 3-way solenoid to an electric sensor float, located in the tank/reservoir. The sensor provides open and close commands to the solenoid valve. The main valve fully opens and closes drip tight upon command, when the solenoid is de-energized, thus enabling accurate and reliable differential level control. Optional Addition: dinamic surge-preventing closing.

Features:• Accurate differential level control• Low power electric actuation• Fast response• Simple and reliable design • Easy installation and maintenance• The application is based on the UL listed valves

Features:• Accurate differential level control• Adjustable differential• Fast response• Simple and reliable design • Easy installation and maintenance• The application is based on the UL listed valves

ALAltitude Pilot Control Valve

The main valve is actuated by a highly sensitive altitude pilot, located outside the tank. The pilot opens or closes the valve in response to the static pressure of the water. The pilot allows for differential adjustments between the maximum and minimum level.Optional addition: dynamic, surge preventing shutoff.

Features:• Accurate differential level control• Fast response• Easy access - no float is located in the tank\reservoir• Simple and reliable design • Easy installation and maintenance• The application is based on the UL listed valves

Zero Pressure Foam Valve Range

ZP/ELZero Pressure Foam Concentrate Electrically actuated Double chamber Control Valve

The valve is installed downstream of the foam concentrate tank and is closed in its normal set position by the master’s main line pressure.When the valve´s 3/2 solenoid is actuated it allows the valve to be forced open by the upstream pressure of its master’s valve water mains. This allows the foam concentrate valve to open even with zero upstream line pressure, ensuring fail safe supply of foam concentrate through the foam proportioner, downstream of the main master valve.

ZP/HMSlaved Hydraulic Pilot actuated Zero Pressure Foam Concentrate Double chamber Control Valve

The valve is installed downstream of the foam concentrate tank and is closed in its normal set position by the master’s main line pressure. The slave valve is forced open through the pilot valve by the upstream pressure of its master’s valve water mains. This allows the foam concentrate valve to open even with zero upstream line pressure, ensuring fail safe supply of foam concentrate through the foam proportioner, downstream of the main master valve.
