Full Bore Flanged Ball Valve for PN10-16-25 Pressure Range

Product Description

Introducing the QFBV model Flange Ball Valve, a masterpiece in valve engineering, designed to provide a full bore, quarter-turn solution for seamless on/off applications. Available in both manual and automatic (electric or pneumatic) versions, this valve is crafted with a robust two-piece construction, offering easy maintenance and a long-lasting operational life. It stands as the preferred choice for industrial applications as well as utility services. Its versatility is unmatched, thanks to a diverse range of seats and body materials that cater to a multitude of industrial purposes.

Testing
- Our Body Strength Test adheres to the stringent BS EN 12266-1 standards, ensuring the valve withstands a pressure of 1.5 times its nominal pressure (PN).
- The Seat Tightness Test is conducted as per BS EN 12266-1, with a testing pressure of 1.1 times the nominal pressure, following ISO 5208 Rate A, guaranteeing optimal leakage protection.
- Pressure Testing: BS EN ISO 5208

Features
- Crafted with precision, the valve boasts a two-piece ductile iron body and a full bore design, promoting efficient flow management.
- Featuring a floating seat, spherical seat, and floating ball coupled with adaptive sealing, this valve offers a fireproof design, making it ideal for fire protection pipelines.
- Engineered with a symmetrical valve seat design, it ensures that switching, installation, sealing, and pressure remain non-directional, enhancing its versatility.
- The valve stem incorporates a wear-resistant bushing design, ensuring minimal torque and extended lifespan. The self-tightening upper seal design guarantees zero leakage under high pressure.
- The upper flange is compliant with the ISO5211 standard, ensuring compatibility and reliability.
- With the ball solution treated or hard chrome plated, this design ensures superior material stability and surface wear resistance, enhancing sealing efficiency and product longevity.
- Easy installation is assured by the handle, which features a positioning lock design.
