Key Features & Benefits

  • 316 Stainless Steel Construction – Premium-grade material delivers exceptional corrosion resistance, durability, and compliance with sanitary standards.

  • Full Port Design – Unobstructed flow path minimizes pressure drop and maintains system efficiency.

  • Tri-Clamp Sanitary Connections – Quick-clamp fittings enable fast installation, easy line removal, and thorough cleaning.

  • L-Port & T-Port Configurations – Versatile flow patterns support diversion, selection, or mixing applications to suit your process needs.

  • Manual Lever Operation – Simple 90° quarter-turn handle provides reliable flow control with clear open/closed position indication.

  • PTFE Cavity-Filled Seats – High-performance seats deliver tight sealing, reduce dead space, and prevent product entrapment.

  • 8-12 Ra Internal Finish – Highly polished internals minimize bacterial growth and facilitate effective cleaning-in-place (CIP).

  • ISO 5211 Direct Mounting Pad – Industry-standard mounting interface allows easy integration with electric or pneumatic actuators for future automation.

  • Triple Stem Seal Design – Live-loaded, self-adjusting stem seals compensate for wear, pressure, and temperature fluctuations to prevent leakage.

  • Three-Piece Body Construction – Enables easy maintenance, seat replacement, and cleaning without removing pipe connections.

How It Works

The Sanitary 3-Way Ball Valve Manual Mod.SIG/42 operates on the quarter-turn ball valve principle. A spherical ball with precision-machined ports (L-shaped or T-shaped) is housed within the valve body. Rotating the manual handle by 90° aligns the ball's ports with the inlet and outlet connections, directing flow according to the selected configuration.

  • L-Port Configuration: The ball features an L-shaped passage. When the handle is turned, flow from the center inlet is diverted to either side outlet, or two separate inlets can be directed to a common outlet – functioning as either a diverter valve or a selector valve.

  • T-Port Configuration: The ball features a T-shaped passage, enabling mixing of two inlet flows into one outlet, or splitting one inlet flow between two outlets.

The manual handle provides visual position indication – when the handle is parallel to the pipeline, the valve is open; when perpendicular, it is closed-. The live-loaded stem seals maintain consistent sealing pressure, automatically adjusting for thermal expansion, contraction, and normal wear.
