Product Description
Product Overview
The Resilient Seated Gate Valve (PN 16, F4) is a high-performance bidirectional sealing valve designed for isolation service across diverse piping applications. Constructed from ductile iron (GGG-40/50 per EN-GJS-500-7/EN 1563), it delivers optimal strength, durability, and corrosion resistance. The elastomer-encapsulated wedge ensures bubble-tight sealing, low operating torque, and reliable performance in water, wastewater, and other neutral media.
Key Features & Benefits
  • Bubble-Tight Sealing: Fully encapsulated resilient wedge provides excellent sealing integrity in both flow directions, minimizing leakage risk
  • Low Operating Torque: Non-lubricated resilient seal design reduces friction for easier operation, even after prolonged inactivity
  • Ductile Iron Construction: Superior tensile strength and impact resistance with excellent pressure-bearing capability
  • Full Bore Design: Minimal pressure drop when fully open, ensuring efficient system flow and reduced pumping costs
  • PN 16 Pressure Rating: Suitable for maximum working pressure of 16 bar (1.6 MPa / 232 psi) at 20°C (68°F)
  • F4 Face-to-Face Dimension: Compliant with EN 558-1 Series 4 / ISO 5752 for direct interchangeability
  • Corrosion Protection: Standard epoxy coating (approx. 250 µm) per EN 14901 for internal and external protection
  • Fire-Safe Option: Available with API 607/API 6FA or ISO 10497 fire-test compliance

Cooling Water Systems
Chemical & Petrochemical Industries
Power Generation
Installation & Operation Notes
Important: Designed for fully open or fully closed service only. Not recommended for throttling or flow control.
Install with stem orientation upwards (preferred) or horizontal. Verify specific design for vertical stem-down installation.
Always depressurize pipeline before operating the valve.
Regular functional exercise recommended for valves in standby service to maintain operational readiness.
