Pneumatic Stainless Steel 3-Way Flanged Ball Valve with Solenoid Valve for Chemical and Water Treatment Flow Control
Designed for industrial fluid automation, the pneumatic stainless steel 3-way flanged ball valve enables flow switching, diversion, and mixing. Equipped with a pneumatic actuator and solenoid valve, it can be expanded with positioners and limit switches for precise modulation and status feedback. Ideal for automated control in chemical, water treatment, oil & gas, and HVAC systems.
Core Selling Points
The Stainless Steel 3-Way Flanged Ball Valve supports flow diversion, distribution or mixing. Its flanged connection provides stable installation for industrial pipelines and equipment skids.
The Pneumatic Actuator enables remote automatic switching and flow-direction control for fluid systems requiring frequent operation and automated control.
An optional Solenoid Valve converts electrical signals into pneumatic actuator movement, simplifying integration with control cabinets, PLC systems or other industrial controllers.
An optional Positioner allows valve-opening adjustment according to the input signal, making the valve suitable for process pipelines requiring flow, pressure or mixing-ratio control.
An optional Limit Switch provides open/closed position feedback to the control system, supporting onsite monitoring, remote confirmation and equipment interlocking.
