Description

This stainless steel flanged ball valve is designed for reliable, high-performance flow control across a wide range of industrial pipeline applications. Featuring PN16/PN40 flanged end connections, it integrates directly into flanged pipework systems and is available in sizes from 1/2" to 4" when used with gaskets, making it suitable for both smaller process lines and larger diameter installations.

The full bore design ensures unrestricted flow through the valve body, minimising pressure drop and making it well suited to applications where maintaining flow efficiency is essential. Constructed from CF8M stainless steel with a 316 stainless steel ball and stem, the valve offers excellent resistance to corrosion and mechanical wear, providing long and dependable service life even in aggressive or demanding media.

PTFE and Viton seals deliver consistent sealing performance across the full operating range of -25°C to +200°C. Pressure ratings of up to 40 bar ensure suitability across a broad spectrum of process conditions. The fire safe design provides added assurance in applications where fire resistance is a requirement, and ATEX approval confirms suitability for use in potentially explosive atmospheres. ISO 5211 direct mount facilitates straightforward actuator fitment for automated installations.

Typical Applications

Key Features & Benefits

  • Fire Safe Design: Provides additional protection in the event of a fire, making this valve appropriate for installations where fire resistance certification is a project or site requirement.
  • ATEX Approved: Certified for use in potentially explosive atmospheres, providing confidence in safety-critical and hazardous area installations.
  • ISO 5211 Direct Mount: Allows pneumatic or electric actuators to be fitted directly without additional bracketing or adaptors, supporting efficient and cost-effective automation.
  • Locking Device Included: Prevents accidental or unauthorised adjustment of the valve position, providing an additional layer of process safety and operational control.
