PLAST-O-MATIC TMBV 3-WAY MANUAL BALL VALVES

Descriptions of PLAST-O-MATIC TMBV

FEATURES

•  Heavy-duty, large diameter shaft to eliminate flexing and breakage.
• Dual shaft seals eliminate leakage.
• PTFE bearing on shaft eliminates friction and wear; stem design is “blow-out” proof.
• PTFE 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, leakproof 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.

DESIGN

• Known as “The Engineered Ball Valve”, Series TMBV provides more features than any other thermoplastic ball valve. With its mirror-polished ball, perfectly machined sealing surfaces, Trunnion centering design, PTFE thrust bearing and O-ring loaded floating PTFE 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 longterm 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 manufacturers specifications.

MATERIALS OF CONSTRUCTION

Series TMBV is molded of Type 1 Grade 1 Geon PVC or Corzan CPVC. Standard O-ring seals are FKM or EPDM. Seats and shaft bearings are PTFE. Standard connections are threaded (NPT or BSP) or socket (Schedule 80 or Metric). For optional materials and connections, please consult factory.
