Sanitary Ball Valve

Sanitary Ball Valve is suitable for any pipeline to control the flow either automatically or manually. Wellgreen sanitary provide sanitary ball valves with full bore or reduced bore design, in stainless steel 304 or 316L with different connection end. The sanitary ball valve is compact and simple design, and easy to maintain, with a full diameter from 1/2″ to 4″, and meet the stringent requirement of high purity sanitary industries of Food, Brewery, Beverage, Dairy, Pharmaceutical, Biopharma etc. Wellgreen is your reliable source for sanitary valves and fittings.


    • Compact and simple design — Easy to install into most any process line, the straight forward floating ball design guarantees a tight seal and permits axial movement while preventing rotation. They are water hammer-safe and completely insensitive to pressure shocks in the pipelines. There are four configurations for sanitary ball valve:

— Sanitary straight way ball valve consists of a valve body, two flanges, a ball and PTFE seats.

— Sanitary 3 way ball valve: It has two configurations: T type and L type. It consists of one valve body, valve covers and PTFE valve seats. It is installed with Tri-clamped or threaded ends.

— Sanitary 2 pieces portable ball valve: a precision made ball is positioned between two PTFE seats inside valve bodies connecting by a clamp. It is installed with clamped or threaded ends. A drain outlet is available on request.

— Sanitary butterfly ball valve: It is composed of two valve bodies, a ball and a sealing unit.

    • Reliable full-flow performance — Sanitary ball valve is full-bore flow valves that provide on/off control with minimal pressure drop. The valve opening has a constant pipeline diameter, which enables fluids to flow freely through the valves when open. Flow restriction is comparable to that of a straight tube. This makes the sanitary ball valve suitable for:
      1. Handling fluids that are viscous or contain solid, semi-solid or abrasive particles;
      2. Use wherever pigging of process lines is a major consideration;
      3. Applications that require gentle product treatment;
    • Automatic or manual control — Sanitary ball valve can be operated by a pneumatic actuator or manually operated by means of a handle.
  • Easy to maintain — Sanitary ball valves design with few moving parts enables easy access to all valve components, making maintenance quick and easy. Durable PTFE gasket valve seats help extending service life. No special tools required for maintenance
