Mining Hydraulic Gyratory Gate Valve, Electro-hydraulic Butterfly Ash Discharging Valve, Discharge Valve

 The hydraulic control valve assembly used in electro-hydraulic push rods mainly consists of pressure relief valves, oil suction check valves, flow control valves, hydraulic lock valves (check valves), etc. Also, based on the operational characteristics of the electro-hydraulic push rod, different functional oil circuit combination valves can be designed to meet its working requirements. Generally, there are features like self-locking for ejection and retracting.

 Retractable and sliding both feature self-locking; operating speeds include variable and non-variable models; the hydraulic actuator's working angle includes horizontal push, upward push (including)

There are several types, including pushing upwards at an angle (both diagonally upwards and downwards), and pushing downwards (including diagonally downwards). The main advantages of electro-hydraulic actuators are as follows:

（1) Compact structure, easy installation, small space requirement, and simple maintenance.

（2) Can start under load with overload protection feature.

（3) The circuit is equipped with a two-way hydraulic lock, allowing it to stop at any position within the specified travel range and automatically lock, while maintaining a constant output force.

（4) Push-pull force and speed (as per customer requirements) are infinitely adjustable with a wide range of driving force.

（5) In case of power failure, the push rod automatically locks to prevent accidents.

（6) Full hydraulic transmission, responsive operation, smooth running, effectively cushions external impacts, stroke control （≥0.5mm）

Pit gates are suitable for bulk density≤2.5t/m3A variety of ore, coal, coke, slag, chemical products, and other loose materials, widely used for bottom unloading in storage for construction materials, metallurgy, chemicals, glass, and other industries.

Structural Features:

  Pleated gate is made of carbon steel welded into shape, with a structure Operates flexibly and reliably without jamming. Equipped with different drive systems, it can meet various operational requirements. The electric jaw gate is fitted with an electric actuator featuring an overload protection device, which prevents motor burnout. It can be remotely controlled or programmatically operated, with reciprocating travel capability. Adjustable position with automatic locking. The electro-hydraulic jaw gate features an electro-hydraulic push rod and full hydraulic transmission, allowing for stepless adjustment of both thrust and pull force. The pneumatic jaw gate utilizes a pneumatic push rod, which can be remotely operated or locally controlled through a combination of accessories.SEFFor manual,DEFFor electric,YEFFor electro-hydraulic operationQEFPneumatic.
