Series LMBV Lateral Reducing Ball Valves

Plast-O-Matic Trunnion Ball Valves are available with an adapter and tee for substantially stronger and more compact valve connections to lateral piping. This design eliminates the need for a reducer, additional length of pipe, and one of the end connections on the ball valve.

Advantages over traditional ball valve tee connections:

• Faster plumbing — reduces labor.
• The overall length is shorter; valve body is partly inside the plumbing tee.
• Design enables removal of valve and access to internals.
• Resists piping stresses better than traditional “reducer” connections.
• Eliminates potential variations in pipefitting.
• Assembly is substantially stronger than pipe + reducer + fittings.

Use in place of zero dead-leg valves:

• Lower cost.
• Virgin, non-pigmented Kynar PVDF and Natural Polypro compatible with all butt fusion piping systems.
• Zero-static area* similar in size to diaphragm valve; uses same concept of turbulence/flushing action to prevent deadleg.
• Valve is threaded into adapter — a true union — easier maintenance, easier changes in piping system.

Note in the photo at right, the smooth, tapered transition the adapter provides from the tee to the ball valve. The outer diameter meets ASTM specs for socket fusion, and the end is suitable for butt fusion. Note also that the distance from the union to the closed valve is well within the standard "six pipe diameters" that defines dead leg.

Design Advantages:

1. Reinforced shaft eliminates stem breaks.
2. Double shaft O-rings.
3. PTFE shaft bearing eliminates friction and wear.
4. PTFE seats backed up with O-rings reduce the wear and tear of repeated cycling.
5. Trunnion Design: Upper and lower supports retain ball under pressure. Trunnion design allows multi-directional flow; means that the valve is in no danger of being installed "backwards."
6. Concentric machined and mirror-polished ball.
7. Dual sliding seats use triple O-rings for balance and maximum leak protection.
8. LMBV Connection provides compact connection and is welded or heat-fused conveniently to tee in main; eliminates reducing bushing, pipe connection and union end — yet still permits access to valve internals.
9. True union end for ease of piping lateral drops from valve.
