Description

This stainless steel ANSI Class 150 flanged ball valve provides dependable full bore flow control for a wide range of industrial pipeline applications. Conforming to ANSI B16.5 Class 150 flange dimensions, it is designed for direct integration into ANSI-standard pipework systems. The full bore design ensures unrestricted flow through the valve body, reducing pressure drop and making it well suited to applications where maintaining pipeline efficiency is a priority. The stainless steel construction delivers excellent corrosion resistance and mechanical strength for reliable, long-term performance in demanding process environments.

R-PTFE ball seats alongside PTFE and Viton seals provide consistent, low-friction sealing performance across the full operating range of -25°C to +200°C and up to 20 bar. ATEX approval confirms suitability for use in potentially explosive atmospheres, and the ISO 5211 direct mount facility allows actuators to be fitted without the need for additional adaptors or brackets. A locking device is fitted as standard to prevent unintended or unauthorised operation.

Typical Applications

Key Features & Benefits

  • ANSI Class 150: Ensures full compatibility with ANSI-standard pipework systems, making this valve a straightforward choice for installations where ANSI flange dimensions are specified.
  • ATEX Approved: Certified for use in potentially explosive atmospheres, providing assurance in safety-critical and hazardous area installations.
  • ISO 5211 Direct Mount: Enables pneumatic or electric actuators to be fitted directly to the valve without additional adaptors or brackets, supporting straightforward and cost-effective automation.
  • Locking Device: Prevents accidental or unauthorised adjustment of the valve position, providing an additional layer of process safety and operational control.
