Tru-Flo valves reduce the worries of routine maintenance expenses while lowering actuation costs by eliminating custom brackets and couplers. Double o-ring protection provides additional defense against leaking through stem and lower operating torque.

Models
  • EA-33NF-SN
  • EA-33NF-EXT
  • EA-3308-SN-L/T
  • EA-407-SN
APPLICATIONS

QSM`s Tru-Flo ball valves are used in a variety of applications. Sanitary ball valves are a 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. Its constant inner diameter allows for free fluid flow—and even allows for the use of product recovery projectiles.

2-Way Valves

QSM`s sanitary 2-way ball valves are available in two models: EA-33NF-SN for Tri-Clamp® style connections, and EA-33NF-EXT for extended butt weld ports. These valves are available in sizes ½ – 6 inch, and optional cavity fillers are also available.

3-Way Valves

CSI supplies QSM`s EA-3308-SN-L/T diverter port 3-way valve with the industry standard 3-way functionality. Available in sizes 1 – 4 inch, this valve diverts from center port to L-Port or T-Port flow patterns and allows a small amount of flow to the closed port.
