Lined Ball Valve
Lined Ball Valve
Horizon offers Lined Ball Valves, its processing polymers such as PFA/FEP by injection moulding is extremely critical as the process requires close monitoring with controlled heating and cooling of the assemblies during the entire moulding stage. These valves are supplied with anti-static devices, which provide protection against potentially dangerous electro-static discharge. This permits direct replacement of a fully lined or sleeved plug valve by horizon lined ball valve without altering the existing pipework.

- The interior body surface as well as the stem and Ball are lined as individual components with PFA, or PVDF/ FEP
- Ceramic balls are also available
- Anti blow-out stem assembly prevents a stem blow-out even when the top gear is disassembled
- The short pattern face to face dimension is in accordance with ANSI B16.10 and ANSI B16.5, 150 lbs (Flange dimension)
- The free floating ball valve principle ensures the ball will seal against the down stream seat ring giving a positive sealing force even when the line pressure is low
- All the inherent design features of a conventional ball valve such as low torque, quarter-turn operation, bubble tight shut off and a minimum pressure drop
- The short pattern face-to-face dimension is in accordance with ANSI B 16.10 and flange dimensions are in accordance with ANSI B 16.5 class 150 lbs
