Overview
Industrial valves are critical components in bulk material handling systems, controlling, isolating, and regulating powders and granular materials. At LVRUI, our industrial valves are engineered for cement plants, mining facilities, chemical processing, and powder handling systems across Southeast Asia, Indonesia, UAE, and other international markets.
These valves are integrated with air slide conveyors, bulk loading systems, and other material handling solutions to ensure efficient, continuous, and dust-free transfer. They are designed to withstand high temperatures, abrasive materials, and long-term operation, optimizing flow control and operational efficiency.
These valves are commonly integrated with air slide conveyors and bulk loading systems.
Main Types
✅ Flow Control Gate Valve – A flow control gate valve is used to regulate cement, fly ash, lime powder and other dry bulk materials discharged from silos, bins and hoppers. It is commonly installed under cement silos, air slide conveyor feeding points and bulk loading systems where stable material flow is required.
✅Lump Breaker – crushes oversize materials before conveying
✅ Electro-Hydraulic Jaw Valve – strong sealing, suitable for heavy-duty bulk discharge
✅ Damper Valve – A damper valve is designed for airflow control in cement plant ducts, dust collector systems, kiln ventilation and industrial exhaust pipelines. Butterfly damper valves and louver damper valves are commonly used when plants need airflow regulation, pressure balancing or high-temperature duct control.
✅ Pneumatic Shut-Off Valve – fast & reliable emergency shut-off for powder/air lines
✅Flap Valve – simple & dust-free low-pressure powder discharge
✅ Double Flap Valve – alternating opening for abrasive & high-temperature materials
✅ Star Discharge Valve – stable discharge for powders and granules
OSHA Dust Collector Standard →
✅ Rod Gate – manual valve for coarse material discharge
✅Rotary Valve – Rotary valves and star discharge valves are used for continuous powder discharge while maintaining air sealing performance. They are commonly installed under dust collectors, silos and pneumatic conveying systems where controlled feeding and pressure separation are required.
✅ Diverter Valve – A diverter valve is used to switch powder or granular material from one conveying route to another. In cement and bulk material systems, diverter valves are often used with air slide conveyors, pneumatic conveying lines and multi-silo distribution systems.
✅ Slide Gate Valve – quick open/close for silo, hopper & screw conveyor discharge
For safety compliance, refer to the OSHA Dust Explosion Standards and industry best practices from CEMA for bulk material handling systems.

FAQs About Industrial Valves
What are industrial valves used for in cement plants?
Industrial valves for cement plants are used to control, isolate, divert or discharge cement powder, fly ash, lime, clinker, gypsum and other bulk materials. They are commonly installed under silos, hoppers, air slide conveyors, dust collectors, pneumatic conveying lines and kiln duct systems.
Which valve is best for cement silo discharge?
For cement silo discharge, flow control gate valves and slide gate valves are commonly used when stable material flow and reliable shut-off are required. Rotary valves or star discharge valves can also be used when continuous feeding and air sealing are needed.
What is the difference between a flow control gate valve and a slide gate valve?
A flow control gate valve is mainly used for adjustable material flow regulation, while a slide gate valve is mainly used for open-close isolation. In cement and powder handling systems, both can be used under silos, bins, hoppers and air slide conveyor feeding points.
Which valve is used for cement plant airflow control?
Butterfly damper valves and louver damper valves are commonly used for cement plant airflow control. They are installed in kiln ducts, ventilation systems, baghouse pipelines and dust collection systems to regulate air volume, pressure and flow direction.
What valve is suitable for dust collector hopper discharge?
Rotary valves, star discharge valves and double flap valves are commonly used for dust collector hopper discharge. They help discharge collected dust continuously while reducing air leakage and maintaining stable system pressure.
Can industrial valves handle abrasive cement and clinker?
Yes. Industrial valves for abrasive cement, clinker and mineral materials can be designed with reinforced blades, wear-resistant liners, heavy-duty sealing structures and high-temperature materials to extend service life in harsh operating conditions.
How do I choose between pneumatic, electric and manual valves?
Manual valves are suitable for simple and low-frequency operation. Pneumatic valves are suitable for fast switching and automated powder systems. Electric valves are suitable for precise control, remote operation and integration with PLC or DCS systems in cement plants.
What information should I provide before requesting an industrial valve quotation?
For an accurate quotation, provide the material name, bulk density, particle size, temperature, installation position, inlet and outlet size, required capacity, working pressure, sealing requirement and preferred actuator type.
