Technical Features & Design Advantages:

1. High-Pressure Resilient Sealing  

• Zero Leakage Performance: EPDM encapsulated wedge achieves EN 12266-1 Class A bubble-tight shutoff at PN25 pressure rating

• Corrosion Prevention: Complete rubber-to-body contact eliminates metal-to-metal seating surfaces

• Temperature Resilience: Maintains sealing integrity from -10°C to 120°C in continuous operation

2. Enhanced Material Construction  

• Reinforced Body Design: Ductile iron body with increased wall thickness to withstand PN25 working pressure

• Corrosion Protection: 300μm fusion-bonded epoxy coating per AWWA C504 standards

• Durable Internals: stainless steel SS431 stem with precision-machined trapezoidal threads

3. OEM Customization Capability  

• Size Flexibility: Available from 2" to 24" (DN50 to DN600) with custom face-to-face dimensions

• Material Options: Alternative seat materials (NBR, Viton), special coatings, and branded components

• Technical Support: Engineering assistance for application-specific modifications and testing

4. Maintenance-Friendly Features

• Lubrication-Free Operation: Self-lubricating bronze bushings and sealed bearings eliminate routine maintenance

• Easy Access: Removable gearbox cover simplifies inspection and service when required
