Schneider electro-hydraulic pressure relief valve HVD306-700-2200-2C

Schneider electro-hydraulic pressure relief valve HVD306-700-2200-2C

HVD 306 is a two-stage electro-hydraulic proportional/servo pressure relief valve used for overpressure protection and closed-loop pressure regulation in high-pressure hydraulic systems. It adopts a linear electromagnet+servo piston slide valve structure, no fixed nozzle, anti pollution, high dynamics, and high precision.

Single stage electro-hydraulic proportional relief valve is a type of electro-hydraulic proportional valve, mainly used in hydraulic systems to achieve continuous and proportional pressure control. Its core function is to adjust the system pressure proportionally based on the input electrical signal (such as current or voltage), combining the functions of traditional relief valves with the advantages of electronic control.

Single stage "usually refers to a direct acting structure, where the proportional electromagnet directly drives the valve core without the need for a pilot stage amplification. Suitable for low flow, medium and low pressure applications. Its structure is simple and its response is fast, but its flow capacity is limited (generally the upper limit overflow is 2-10 L/min).

Core advantages:

High dynamic: millisecond level response, suitable for fast pressure fluctuation scenarios

High precision: linearity<2%, repeatability<1%, supporting closed-loop pressure control

No fixed nozzle: pure slide valve structure, anti pollution, easy to maintain

Strong robustness: sturdy structure, suitable for harsh industrial working conditions

Easy to debug: The internal hexagonal S8 can be adjusted to zero position
