Known as “The Engineered Ball Valve”, Series TMBV provides more safety and design features than any other thermoplastic ball valve. With its mirror-polished ball, perfectly machined sealing surfaces, Trunnion centering design, Teflon thrust bearing and O-ring loaded floating Teflon seats, the True Blue three-way ball valve offers smooth turning even in difficult applications. The floating seats automatically compensate for seat wear, and after long-term cycling, the carriers can easily be returned to their original position simply by tightening the union nuts.

The 2-hole ball design is standard; it is ideal for applications where flow cannot be mixed. To prevent a momentary no-flow (“dead-head”) condition, an optional 3-hole ball is available. Please specify when ordering.

The top to bottom “Trunnion” design permits flow and pressure in either direction, and eliminates the stresses inherent to a ball secured only at the top. An ultra smooth flow path virtually eliminates turbulence and pressure loss and permits flow rates that far exceed pipe manufacturer’s specifications.

Features:

• Valve shaft (stem) reinforced with stainless steel rod to eliminate flexing and breakage.
• Dual shaft seals eliminate leakage.
• Teflon® bearing on shaft eliminates friction and wear; stem design is “blow-out” proof.
• Teflon seats energized with O-rings eliminate wear and improve cycle life.
• Trunnion design eliminates lateral ball stress and allows downstream piping to be disconnected under full line pressure.
• Smooth flow path minimizes pressure loss.
• Fully concentric and mirror polished ball assures smooth, leak-proof operation.
• Three true-union ends for ease of piping installation and removal; helps lower costs and reduce footprint.
• Choice of 2-hole or 3-hole ball.

Each valve is 100% individually inspected and tested prior to shipment.
