QSM Tru-Flo Ball Valves
Central States Industrial (CSI) offers Tru-Flo ball valves from QSM. These next generation ball valves are live-loaded with self-adjusting packing and a design that is specifically manufactured for high cycle applications.
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
QSM 2-Way Ball Valves are available in the following sizes: ½, ¾, 1, 1½, 2, 2½, 3, 4, and 6 inch.
QSM Tru-Flo specializes in the manufacturing and development of stainless steel and carbon steel valves used worldwide in sanitary and industrial applications.
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.
Multiport 3-Way Valves
If you need a complete, positive seal at every port, QSM's EA-407 series multi-port valve is the valve for you. It provides a true positive seal at every port and is available in L-Port or T-Port configurations and sizes ½ – 4 inch. 4-way double LL ball valves are also available.
