Flanged Ball Valves
Bolted flange connections suit industrial piping and allow the valve to be removed for maintenance.
Welded Ball Valves
Welded connections integrate the valve into the pipeline without bolted end joints.
Floating Ball Valves
Line pressure moves the ball against the downstream seat to form the shut-off seal.
Trunnion-Mounted Ball Valves
The ball is supported at its rotational axis, with the seats providing sealing contact.
Top-Entry Ball Valves
Access through the top of the body provides a different maintenance arrangement from split-body designs.
V-Port Ball Valves
A shaped port changes the opening area as the ball rotates, supporting flow regulation.
Válvulas de esfera elétricas
An electric actuator provides remote quarter-turn operation for automated piping systems.
Válvulas de esfera pneumáticas
A compressed-air actuator opens and closes the valve as part of an automated control sequence.
Ball Valve Flow Patterns
Two-way ball valves open or close a single flow path. Three-way and four-way designs route flow between connected lines, making them useful for switching duties and distribution systems. The port arrangement determines which passages are connected in each operating position.
Full-Port Ball Valves
A bore close to the pipe diameter provides a clear flow path when the valve is open.
Two-Way Ball Valves
A single passage provides straightforward isolation between two pipe connections.
Three-Way Ball Valves
Three connections allow flow to be switched or diverted according to the ball’s port arrangement.
Four-Way Ball Valves
Multiple passages connect and switch flow between four pipe connections.
Segmented Ball Valves
A shaped ball segment varies the flow opening as it rotates, providing a construction suited to control duties.
High-Pressure Ball Valves
Dedicated pressure-rated models serve piping duties beyond the range of general-purpose ball valves.
As aplicações e usos mais importantes das válvulas esfera
Water Systems
Ball valves provide quarter-turn isolation in water distribution, treatment and utility piping.
Óleo e gás
Floating and trunnion-mounted designs provide isolation across different pipeline and facility services.
Pharmaceutical Processing
Ball valves serve process and utility lines, with hygienic applications requiring the appropriate valve construction and surface finish.
Ball Valve Design Features
Ball valves combine a compact shut-off mechanism with a choice of bore sizes, materials and operators. These features make them useful across both manual piping systems and automated processes.
Full-Bore Flow
A full-bore design keeps the passage close to the pipe bore, helping reduce flow restriction when the valve is open.
Quarter-Turn Operation
A 90-degree turn moves the ball between open and closed positions. The same mechanism can be operated by a lever, gearbox or actuator.
Seat Options
The seat provides the sealing surface around the ball. Seat material is an important part of matching a ball valve to its operating temperature and medium.
Body and Trim Materials
Carbon steel and stainless steel options allow the body and internal components to suit different process fluids and working environments.
