TapcoEnpro Slide Valves

Pushing the frontier of slide valve technology to withstand failure even under the most extreme operating conditions

TapcoEnpro Slide Valves are designed for rigorous operating conditions. Originally designed for the tough specifications of the iron ore industry, the TapcoEnpro Boltless valve is able to withstand 1650°F (900°C) and 710 PSI (49 Bar) differential pressure.

With these rigorous design specifications, the TapcoEnpro slide valve is able to offer outstanding performance in FCCU service as well.

Because TapcoEnpro slide valves have been designed to outperform industry standards for safety, performance and reliability, they have become the valve-of-choice of those in the severe environment process industries. The proof is in the numbers.

TapcoEnpro had more valves in operation throughout the world than all other valve manufacturers.

Our slide valves improve process efficiency, safety and reliability. Many of our slide valve innovations remain exclusive to TapcoEnpro and are protected under U.S. and foreign patents. Most of our valve designs help set industry standards. For example, in 1990 we addressed the industry- wide problem of seat plate warping with our Hot Stub Design which has become the standard in designs.


Unique Bolt-Less SlideValve™ Design

In 1998, TapcoEnpro introduced the Bolt-Less SlideValve™ design to solve a maintenance issue that had troubled refiners for decades. Our Bolt-Less SlideValve™ Design is the most important innovation yet when it comes to eliminating excessive downtime due to bolt failure.

Preventing premature valve failure has been a primary concern of TapcoEnpro. Our Bolt-Less SlideValve™ design eliminates the loading on the internal bolts that leads to deterioration and eventual failure of the valve. Since bolts are never placed in tension, you never have broken bolts inside the valve body. The orifice plate, disc and guide assembly carries the entire internal loading of the valve.

The cross-sectional area of the guides holds the disc in place. The Bolt-Less slide valve achieves approximately 8 times the effective stress area of conventional bolting. Additionally, machined surfaces that mate together require no gasket seating and eliminate resurfacing, reworking or retapping of holes in the seat plate caused by bolting problems.

Key features

Designed for rigourous operating conditions, the TapcoEnpro slide valve has helped lead the way with many patented design enhancements.

Operation
  • Flawless performance in severe service conditions (1650°F / 900°C and 710 PSI / 49 Bar differential pressure)
  • Meets all requirements for FCCU service
  • Improve process efficiency
Available designs
  • TapcoEnpro provides both a bolted and boltless design
  • The boltless design offers reduced maintenance in refinery operations
    • Eliminating the need to load internal bolts that can lead to overall valve deterioration and failure
    • Achieves 8 times the effective stress area of conventional bolting
    • Machined mating surfaces require no gasket seating so resurfacing and retapping of holes in seat plate is eliminated
    • Eliminating problems arising from bolts
