Testing
- Our Body Strength Test strictly complies with the rigorous BS EN 12266-1 standards, ensuring that the valve can withstand pressures of up to 1.5 times its nominal pressure (PN), showcasing its resilience and reliability.
- The Seat Tightness Test is conducted in accordance with BS EN 12266-1, using a testing pressure of 1.1 times the nominal pressure, and adhering to ISO 5208 Rate A. This ensures excellent leakage protection, guaranteeing optimal performance and durability.
- Pressure Testing: BS EN ISO 5208
Features
- Exquisitely crafted, the valve features a durable two-piece ductile iron body and a full bore design that promotes efficient flow management, ensuring optimal performance in diverse applications.
- Designed with a floating seat, spherical seat, and floating ball along with adaptive sealing, this valve incorporates a fireproof design, making it perfectly suited for fire protection pipelines.
- With its engineered symmetrical valve seat design, this valve ensures that switching, installation, sealing, and pressure handling remain non-directional, greatly enhancing versatility and functionality.
- The valve stem is equipped with a wear-resistant bushing design, minimizing torque requirements and extending lifespan. Its self-tightening upper seal design provides zero leakage under high pressure, ensuring reliability.
- The upper flange meets ISO5211 standards, guaranteeing compatibility and reliability across various systems.
