Product Description
Ball Valve Model 408 is designed for shutting off the flow of the working medium.
A characteristic feature of this model is its dismantling (split) body and the option of manufacturing it in a two-piece version. The valve is available in a full bore or reduced bore design. The disassemblable construction allows for easy replacement of seals and the ball, which significantly facilitates valve maintenance.
Design Features:
- Dismantling (split) body (2-piece construction)
- Full bore or reduced bore design
- Easy access to internal valve components
