Advantages of Ductile Iron Handwheels
vs. Carbon Steel:

1.Higher Strength & Toughness -
Resists impact and deformation better.
2.Superior Corrosion Resistance -
Longer lifespan in harsh environments.
3.Enhanced Vibration Damping -
Smoother operation, reduces fatigue.

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

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.
