Electro Hydraulic Jaw Valve for Silo & Hopper Discharge
(Katup Jaw Elektro-Hidraulik untuk Pembuangan Silo & Hopper)
Heavy-duty electro-hydraulic jaw valve for silos, hoppers, and bulk material discharge systems
Overview
The electro hydraulic jaw valve is a heavy-duty discharge device designed for controlled material flow from silos and hoppers.
The electro hydraulic jaw valve is a heavy-duty discharge device designed for controlled bulk material flow from silos and hoppers. By using an electro-hydraulic actuator to drive the jaw plates, the valve ensures stable opening and closing, precise discharge control, and reliable sealing performance.
This electro hydraulic jaw valve is widely used in cement plants, fly ash handling systems, mining facilities, and industrial bulk powder processing lines. Its robust structure and high-pressure hydraulic drive make it suitable for handling abrasive and high-density materials such as cement, clinker, limestone, powders, and granules.
Designed for demanding industrial environments, the electro-hydraulic jaw valve provides long service life, reduced maintenance, and consistent material discharge under continuous or batch operation conditions.

Working Principle
✅ Electrical signal triggers hydraulic actuator
✅ Cylinder drives jaws to open/close quickly
✅ Tight sealing prevents material leakage
✅ Controlled discharge avoids sudden surges
✅ Prevents bridging and material accumulation at outlet
✅ Suitable for continuous or batch feeding processes
The electro hydraulic jaw valve operates by converting electrical control signals into hydraulic power. The hydraulic cylinder drives the jaw plates to open or close smoothly, allowing precise control of material discharge.
This controlled movement prevents sudden surges, reduces material bridging, and ensures stable flow at the silo or hopper outlet. The tight sealing structure minimizes dust leakage and improves operational safety, especially in bulk powder handling systems.
For industrial safety requirements, refer to OSHA guidelines on combustible dust hazards.
Applications
✅ Cement plants
✅ Fly ash storage systems
✅ Bulk powder handling systems
✅ Lime & gypsum storage silos
✅ Pneumatic conveying systems
✅ Mining & industrial discharge systems
✅ Silo bottom & hopper outlet systems
For controlled powder discharge, the electro hydraulic jaw valve can be integrated with an Air Slide Conveyor discharge system.
Advantages
✅ Prevents material blockage and bridging
✅ Fully sealed and dust-free discharge
✅ Fast opening and closing for efficient feeding
✅ High wear resistance for abrasive materials
✅ Strong electro-hydraulic drive performance
✅ Long service life with minimal maintenance
✅ Suitable for harsh industrial environments
For oversized or compacted material handling, the system can be combined with a Lump Breaker to ensure smooth downstream flow.
FAQS About Electro-Hydraulic Jaw Valves
Q1: What is an electro hydraulic jaw valve used for?
A: An electro hydraulic jaw valve is used for controlled discharge of bulk materials from silos and hoppers. It is especially suitable for heavy-duty applications involving cement, fly ash, clinker, and other abrasive powders.
Q2: What is the difference between a jaw valve and a slide gate?
A: Jaw valves use opposing jaw plates driven by hydraulic force, offering stronger discharge control for heavy materials. Slide gates are typically used for lighter-duty applications with lower material loads.
Q3: Can an electro hydraulic jaw valve handle abrasive materials?
A: Yes. Electro hydraulic jaw valves are designed to handle abrasive and high-density materials, with reinforced structures and wear-resistant contact surfaces.
Q4: Is the electro hydraulic jaw valve suitable for continuous operation?
A: Yes. It can operate in both continuous and batch discharge modes, depending on system requirements and hydraulic control settings.
Q5: How do I select the right jaw valve size?
A: Selection depends on silo outlet size, material properties, discharge rate, and operating pressure. LVRUI engineers can provide customized recommendations based on your application.
