Reduced Risk of Damage- Avoids direct contact with valve body, preserving structural integrity. Importance of High-Strength Bolted Connectionin 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 replacementAdvantages & Applications of Soft Seal Gate Valvesin Water Supply/Drainage Systems1.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.
