Dorot Valves: Technical Overview and Application in Hydraulic Systems
Dorot engineering solutions for hydraulic system automation
Dorot Control Valves (Israel) is a global leader in the development and manufacture of automatic hydraulic valves. The brand's technologies, part of MAT Holding, ensure autonomous control of flow parameters (pressure, flow, level) using the energy of the working medium itself. Dorot valves are used in critically important systems: from municipal water supply networks and industrial circuits to fire extinguishing systems and high-tech irrigation.
The products are certified according to key international standards such as ISO, AWWA, FM, UL, and WRAS, which confirms their reliability for the most critical applications. EV Group China organizes direct deliveries of Dorot valves to solve the following engineering tasks:
- Hydraulic optimization and protection of water supply and wastewater networks.
- Automation and efficiency improvement of drip and sprinkler irrigation systems.
- Supply of fire extinguishing systems, including deluge and sprinkler installations (solutions with FM/UL certification).
- Flow regulation at energy and oil and gas industry facilities, including for working with corrosive media.
- Integration into Smart Water projects and modernization of urban infrastructure.
Air Valves
This type of valve performs three critical functions: releasing large volumes of air when filling the pipeline (kinetic function), introducing air to prevent vacuum collapse when emptying the system, and discharging small volumes of dissolved air during operation under pressure (automatic function). Their use is mandatory for protecting pipelines from cavitation, water hammer, and reducing the efficiency of pumping units.

Hydraulic Control Valves
Dorot's key product line, featuring diaphragm valves with hydraulic control. Their operation is based on the pressure difference in the control chamber and in the pipeline. Thanks to the modular design and a wide selection of pilot regulators, the basic valve can be configured to perform various functions: pressure reduction "downstream", pressure maintenance "upstream", flow limitation, reservoir level control, and protection against water hammer.

Back-flushing Valves
Specialized valves designed to automate cleaning cycles in water treatment and filtration systems. They provide controlled flow diversion for back-flushing filtering elements (sand, disc, screen filters), minimizing water loss and eliminating the need for manual intervention.

Non-return Valves
Valves designed to prevent reverse flow of the working medium, which is a key factor in protecting pumping equipment and pipelines. The design of Dorot and A.R.I. valves ensures smooth closing, which effectively dissipates flow energy and minimizes the risk of water hammer when pumps stop.

Backflow Preventers
Complex devices for protecting potable water supply networks from secondary contamination caused by back-siphonage or backpressure effects. These systems, such as pressure vacuum breakers (PVB) and reduced pressure zone (RPZ) devices, create a physical air gap, ensuring compliance with strict sanitary standards.
