Valve Key Features

Chain wheel and Gearbox operation
Advantages of chain wheel operation

1.Easy Installation & Alignment
Chain sprockets can be quickly mounted on shafts with keyways or set screws, and their tooth profile ensures smooth engagement with the chain.

2.High Torque Transmission with Minimal Slip
Sprockets provide positive drive (no slippage) compared to belts, making them ideal for heavy-load applications like conveyors or industrial machinery.

3.Durable & Low Maintenance
Made of hardened steel or corrosion-resistant materials, sprockets withstand harsh environments and require only periodic lubrication.

4.Adaptable to Multiple Chain Types
Compatible with roller chains, silent chains, or timing chains, allowing customization for speed, precision, or noise reduction needs.

Lifting Lugs/Holes 
1.DN250 and above
2.With high-strength carbon steel lifting ring,
3.In line with relevant lifting standards.

Advantages of Soft Seal Gate Valves with Lifting Lugs/Holes
   Ease of Installation
Simplifies safe handling and positioning using lifting equipment.
   Reduced Risk of Damage-
 Avoids direct contact with valve body,
    preserving structural integrity.
 

Importance of High-Strength Bolted Connection
in Soft-Seal Gate Valves (Body & Bonnet)
 1.Ensures Leak-Free Sealing-Maintains tight joint integrity under              pressure and thermal cycling.  
 2.Resists Mechanical Stress-Withstands high loads/vibration without        deformation or failure.  
 3.Simplifies Maintenance-Allows safe disassembly/reassembly for            inspection or part replacement

Advantages & Applications of Soft Seal Gate Valves
in Water Supply/Drainage Systems

ANSI BS DIN ISO Many International standard flangeds connection

1.Zero Leakage-Elastic seals (e.g.,EPDM,NBR) ensure tight shutoff,critical for  potable water and wastewater systems.

2.Corrosion Resistance-Withstands aggressive media (chlorinated water, sewage) without seal degradation.

3.Ease of Operation-Low torque design enables manual/small actuator use,ideal for frequent on-off cycles.

4.Low Maintenance-Replaceable seals reduce downtime and costs in large-scale municipal networks.

5.Versatility in Media-Handles sludge,suspended solids,and non-abrasive fluids common in drainage systems.
