Key Features & Technical Advantages:

1. Revolutionary Replaceable EPDM Seat System

  • Dramatically Reduces Downtime: The seat can be replaced quickly and easily without specialized tools or disassembling the valve body from the pipeline in many cases. This cuts maintenance hours and costs.

  • Superior Sealing & Resilience: The EPDM (Ethylene Propylene Diene Monomer) rubber seat provides excellent bubble-tight sealing (EN 12266-1 Class A) and is resilient to aging, ozone, and water-based fluids.

  • Extends Valve Service Life: When the seat wears, simply replace it—not the entire valve. This sustainable design offers a significantly lower lifetime cost

2. Robust Ductile Iron (DI) Disc for Durability

  • High Strength & Impact Resistance: The DI disc (Grade EN-GJS-500-7) offers superior tensile strength and durability compared to standard cast iron, ensuring reliable performance and resistance to water hammer.

  • Cost-Effective Performance: Provides an optimal balance of mechanical strength and cost, making it ideal for a wide range of general industrial applications.

3. Instant Manual Control with Hand Lever

  • Quick 90° Operation: The ergonomic hand lever allows for rapid open/close control with a simple quarter-turn.

  • Clear Visual Indication: Integrated position indicators (Open/Closed) provide immediate visual confirmation of valve status for operational safety.

  • Low Operating Torque: The efficient disc design minimizes friction, ensuring smooth and easy lever operation.

4. Space-Saving Wafer Design

  • Compact & Lightweight: The wafer body installs directly between ANSI or DIN flanges, offering a lighter and more space-efficient solution than lug-type valves.

  • Simplified Installation: Reduces installation time and hardware requirements, lowering overall project costs.
