DYLV-0.6 Type Electro-Hydraulic Flat Sluice Valve, Manual (Electro-Hydraulic) Plug Valve

　The PZ series electric hydraulic push rod flat gate (abbreviated as electric hydraulic push rod) is suitable for reciprocating linear (or reciprocating rotational) motion. It is a primary control equipment for flow and conveying quantity of powdery, granular, particle, and small piece materials. It can also be used in long-distance and high-altitude hazardous areas and can be connected to computers for centralized (programmed) control. It is now widely used in industries such as metallurgy, mining, coal, electricity, machinery, grain, cement, chemicals, water conservancy, and transportation, serving as an indispensable general power source.

 

II. Principle and Function:

　　1. Principle of Operation: The electro-hydraulic actuator is powered by an electric motor, which, through forward (or reverse) rotation, drives hydraulic oil to be output as pressurized fluid through a bidirectional gear pump. The oil then flows through an integrated oil circuit block to the working cylinder, thereby achieving reciprocating motion of the piston rod.

　　2. Overload Automatic Protection Function: During the operation of the electro-hydraulic push rod, if the external force on the piston rod exceeds the rated output force or the piston reaches the end position, and the motor continues to rotate, the oil pressure in the circuit will rise to the set pressure. The overflow valve will then quickly and accurately overflow, thereby achieving automatic overload protection. Although the motor is still rotating, it will not be damaged.

　　3. Self-locking Function: The hydraulic push rod's oil circuit module is designed with a pressure self-locking mechanism. Once the motor stops rotating, the piston rod immediately remains at a specific position, and the pressure oil remains in a pressure-holding state.

　　4. Speed can be infinitely adjusted within the designated speed range, as per customer requirements.

　　5. Push and pull forces can be infinitely adjusted within the designated output power range as per customer requirements.

　　6. Can be infinitely adjusted within the designated travel range according to customer requirements.
