Tri-Clover® 5308/5309 Series Ball Valves

Alfa Laval's Tri-Clover® 5308 and 5309 Series ball valves are dependable and versatile valves, ideal for applications which require a full-flow body design to minimize line turbulence and pressure drop. These ball valves are known for their reliability and easy maintenance, and they are an economical drop-in replacement for the Tri-Clover 4300 series.

The 5308 (Tri-Clamp® connections) and 5309 (butt weld connections) valves are available in seven sizes with manually operated handles. An optional encapsulated seat reduces the risk of product entrapment.

Models

  • 5308
  • 5309

5308 and 5309 ball valves are available in the following sizes: ½, ¾, 1, 1½, 2, 3, and 4 inch.

APPLICATIONS

5308/5309 Series ball valves are suited for a variety of applications. Sanitary ball valves are the go-to valve for applications like water, air, and ingredient lines, where reliability and ease of maintenance are priorities. The full-bore design is ideal for handling viscous fluids or fluids with solids or semi-solid particles while minimizing turbulence and pressure drop. A constant inner diameter allows for free fluid flow and even allows for the use of product recovery projectiles.

STANDARD DESIGN

The Tri-Clover 5308/5309 ball valve consists of a stainless steel body that houses a rotating ball. The rotating ball is sealed in the body with a PTFE seat that either partially or fully encapsulates the ball. The valve is activated by a stainless steel handle that opens and closes the valve through a quarter turn. The stem and packing design eliminate the possibility of the stem becoming dislodged or blown out.

The 5308/5309 valve is available in seven end connection sizes: ½, ¾, 1, 1½, 2, 3, and 4 inch. Both Tri-Clamp (model 5308) and butt weld (model 5309) connections are available.
