Weir Diaphragm Valve (Tru-Trol)

weir diaphragm valve

The Tru-Trol Enhanced Weir type Diaphragm Valve is designed for leak-proof control of abrasive and corrosive liquids, suspensions, slurries, and pulps, while at the same time providing laminar flow characteristics of Straight Through diaphragm valves.

Tru-Trol Advantages

  • Designed for higher operating pressures than the competition (125 to 200 PSIG)
  • Compact design conforming to conform to ASME/ANSI B16.10. interchangeable with most solid wedge, double disc, and resilient wedge gate valves as well as short pattern plug and ball valves.
  • Ductile Iron construction, as opposed to cast iron, reduces damage from wear and tear and improves long-term reliability.
  • Tru-Trol body and Duo-Flex diaphragm are designed to provide streamlined laminar flow profiles of a Venturi with minimal change in incremental cross sectional area, resulting in minimum pressure drop
  • Unique body design results in shorter stroke, reducing diaphragm stress and providing longer life
  • By design, Tru-Trol delivers zero fugitive emissions. Additionally, sealed bonnet is also available as an option
  • The Duo-Flex diaphragm can easily be replaced in line. The straight through design also facilitates the use of brushes or rods to clean the valve.
  • Double-studded diaphragm, v/s single-studded, deliver better seal and longer life
  • Standard TGIC Polyester powder coating
  • Standard Rising Stem, Travel Stop Nut, and Stem Cover for Manual Valves
  • Standard Adjustable Travel Stops on all Pneumatic Actuated Valves
  • Standard Adjustable Closing Stops on all Pneumatic Operated Valves
  • Wide range of valve body materials, coatings/linings and diaphragm material (See link below for full listing)
