DSZ-500 Curved Valve, Frost-Proof Device Gate

Electromagnetic hydraulic flap gate with power failure reset is widely used in industries such as building materials, metallurgy, mining, power, chemical engineering, etc., serving as the discharging control device for various material dropping systems.

Structural Features

Easy installation directly below the material storage. Powered by electro-hydraulic actuators, compact design for convenient mounting. Smooth operation with low failure rate, capable of quickly cutting off the material flow. During power outages, the electro-hydraulic actuator can automatically reset and close the gate to prevent spillage.

Operating Principle

With power failure resetElectro-hydraulic flap gateComposed of the main body, an electromagnetic hydraulic push rod with power-off reset, sector gate, shaft, gears, seals, and actuator, etc. The operation of the electromagnetic hydraulic push rod drives the gears to rotate the sector gate around the shaft center, causing the two sector gates to open to the sides, allowing the material to fall. Once the receiving device is fully loaded, the electromagnetic hydraulic push rod then resets the sector gate, closing off the falling material.
