What Is a Floating Ball Valve (DIN)?
A floating ball valve is a valve type in which the ball is positioned “floating” inside the body and line pressure pushes the ball against the downstream seat to achieve tight sealing. This principle offers low torque, fast on–off operation and an economical total cost of ownership, particularly in small to medium sizes. The floating ball valve (DIN) configuration is engineered to match PN16/PN25/PN40 ratings, EN 1092-1 flanges and EN 558 face-to-face dimensions.
Technical Advantages and Application Areas
- Low torque requirement and fast operation
- Tight leakage classes with soft-seat design; optional metal-to-metal sealing
- ISO 5211 top flange for actuator compatibility
- Fire-safe (ISO 10497 / API 607) and low fugitive emission (ISO 15848) options
- EN 10204 3.1 material certification and full traceability
Where is it used? In refinery and petrochemical lines, solvent and utility fluid transfer, auxiliary systems of power plants, water–wastewater and seawater applications, as well as general process industries. The compact body and full-bore options reduce pressure drop and provide advantages in lines that require pigging.
Installation – Operation – Maintenance Tips
- Alignment and cleaning: Clean the inside of the line before installation; misalignment can accelerate seat wear.
- Torque setting: Allow a safety margin in actuator sizing; excessive torque shortens seat life.
- Commissioning: Check sealing surfaces during the first open–close cycles; verify packing adjustment to minimise fugitive emissions.
- Periodic maintenance: Packing, stem bearings, stop limits and bolted connections should be periodically inspected.
- Spare parts management: Seat sets, packing and gland kits should be included in critical stock.
Selection Guide: How to Specify the Right Floating Ball Valve (DIN)?
- Fluid & temperature range: Assess corrosion / erosion risk and compatibility with seat / elastomer materials.
- Pressure & flow: Define continuous / peak values and acceptable pressure drop.
- Connection & PN rating: Select EN 1092-1 flange type and match PN16 / PN25 / PN40.
- Bore & seat type: Choose between full-bore / reduced-bore and soft-seat / metal-seat options.
- Actuator & safety: Determine pneumatic / electric / manual operation, ESD requirements and locking needs.
- Testing & documentation: Define EN 12266 test plan, EN 10204 3.1 certificates, coating system and third-party inspection (TPI) scope.
