Description

This 3-piece stainless steel ball valve offers a robust and versatile solution for flow control across a wide range of industrial applications. The 3-piece body design allows the valve to be removed from the pipeline for maintenance or inspection without disturbing the end connections, reducing downtime and simplifying servicing. Full bore construction ensures minimal flow restriction and pressure drop across the valve, making it well-suited to applications where flow efficiency is a priority. The CF8M stainless steel body and 316 stainless steel ball provide excellent corrosion resistance and mechanical strength, while R-PTFE seats and PTFE seals deliver reliable sealing performance across the full operating range.

Rated to a maximum of 82 bar and suitable for temperatures from -25°C to +200°C, this valve is appropriate for demanding process conditions across sectors including chemical, food and beverage, oil and gas, and general industry. ATEX approval confirms suitability for use in potentially explosive atmospheres, and the ISO 5211 direct mount facility enables straightforward actuator fitment for automated applications. A locking device is included as standard to prevent unintended operation.

Typical Applications

Key Features & Benefits

  • 3-Piece Body Construction: Allows access to the valve internals for maintenance or cleaning without removing the end connections from the pipeline.
  • Wide Operating Temperature Range: Suitable for use from -25°C to +200°C, making this valve appropriate for high-temperature applications.
  • ATEX Approved: Certified for use in potentially explosive atmospheres, assuring 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 operation or unauthorised adjustment of the valve position, adding an additional layer of process safety and control.
