SLV

Electric 3-Piece Ball Valve

The SLV Electric 3-Piece Ball Valve pairs a rugged three-piece ball valve with an electric actuator, delivering automated on/off or modulating control in a single package. Because the body is built for in-line servicing, it suits demanding process duties where both automation and easy maintenance matter.

Product Benefits

  • In-line serviceability: The three-piece body can be opened up while the centre section stays aligned in the pipeline, so seats and seals are renewed without cutting the valve out of the line.
  • Shorter shutdowns: Maintenance stays quick and downtime short compared with welded or one-piece designs.
  • No air supply needed: Electric actuation removes the need for a compressed-air supply and lets the valve be driven straight from the control system.
  • On/off or modulating: Actuators are available for simple open/close duty or for regulating control using standard industrial signals.
  • Position feedback: Feedback contacts keep the control room informed of the valve position at all times.

Where It's Used

  • Automated process lines: The valve is a natural fit for automated process and utility lines where quarter-turn isolation or flow adjustment must happen remotely, on a schedule, or as part of an interlock.
  • Skids and treatment plants: Typical homes include pump and skid packages, treatment systems, and general process piping.
  • Electric automation plants: It suits plants that run on electric rather than pneumatic automation.
  • Wide connection choice: Threaded, flanged and welded end styles let the same valve family slot into very different piping practices, from compact instrument lines up to larger process headers.

Good to Know

  • Body material options: Bodies and balls come in several stainless steel grades as well as carbon steel and duplex stainless.
  • Seat materials: Seats range from PTFE-based materials to elastomers such as NBR and VITON.
  • Match to the medium: Matching the body and seat to the medium and its temperature is the key selection step.
  • Actuator range: The actuator line covers both on-off and regulating versions across a range of supply voltages, all working through the standard quarter-turn rotation.
  • Decide control type early: When specifying, settle early on whether you need simple open/close or true modulating control with an analogue command signal, as this determines the actuator model.
