Double Pendulum Valve Services

OP Engineering Group is a leading manufacturer and supplier of high-quality Double Pendulum Valves (DPV) used in cement plants, sponge iron (DRI), power plants, and other bulk material handling industries.

Known for precision engineering and durability, OP Engineering Group manufactures robust and leak-proof double pendulum valves that ensure controlled discharge of materials while maintaining airtight sealing in high-temperature and dust-prone environments.

Our valves are designed for continuous industrial operation, providing reliable performance, minimal maintenance, and long service life.

A Double Pendulum Valve is a mechanical device used to control the discharge of bulk materials from hoppers, cyclones, bins, and silos while preventing air leakage.

It consists of two flaps (pendulums) that open and close alternately, ensuring:

• Continuous material discharge
• Airlock sealing system
• Prevention of air leakage
• Controlled flow of material

This makes it an essential component in systems where pressure sealing and material handling are critical.

OP Engineering Group manufactures DPVs in various sizes and specifications based on application requirements:

• Size Range: As per client requirement
• Material: Cast Iron, Cast Steel, Alloy Steel
• Temperature Resistance: Suitable for high-temperature applications
• Design: Heavy-duty industrial design
• Operation: Gravity-based or motorized (optional)
• Sealing Type: Air-tight sealing system

Our valves are customized to ensure maximum efficiency and compatibility with plant systems.

Double Pendulum Valves are widely used in:

• Cement Plants
• Sponge Iron (DRI) Plants
• Power Plants
• Steel & Metallurgical Industries
• Chemical Processing Plants
• Dust Collection Systems
• Ash Handling Systems

They are commonly used under cyclones, hoppers, silos, and preheater systems for material discharge.

OP Engineering Group manufactures complete DPV assemblies along with all essential components:
