The internal valve features low head loss with a full-port design, which opens with minimal head pressure and closes with any back pressure exerted on the valve. The 750 Series valve is provided with two cleanout ports and is manufactured from carbon steel with an epoxy coating. The bolting dimensions are in accordance with ANSI 125/150# pattern.

The Style 750 inline valve offers a number of other features, including:

  • Availability in sizes 2 to 36 inches
  • Abrasion-resistant elastomer
  • Maintenance-free design
  • Exceptional backflow prevention

In addition, a unique advantage of the valve is its ability to offer zero valve slam, which can often occur upon pump shutdown. Valve slam is the amount of energy applied to the downstream seat of any valve when flow comes back or attempts to close the seat when a pump shuts off. If the energy is great enough, it will destroy a steel bodied valve. With the Series 750, the rubber duckbill check valve inside absorbs the energy that would normally be absorbed by a steel valve.

Proco Products Inc.is an exhibitor at WEFTEC.15 and can be found at Booth 1417.
