ATWOOD & MORRILL®

Forged Parallel Slide Valves

Forged Parallel Slide Gate valves are designed for performance in high pressure, high temperature applications. The design provides reliable, non-jamming operation.

KEY FEATURES & BENEFITS

  • Body: One piece forging to minimize material defects and deliver exceptional durability.

YOKE ROD UPPER STRUCTURE

  • Provides easy access to packing gland and rigid support for operator.

INDEPENDENT DISCS

  • Free to rotate and align with body seat rings, prevents thermal binding.

SEATING SURFACES

  • Alloy 6 on Inconel Butter Layer seating surfaces (seat rings and discs) provides superior bonding to the base material and supports a longer life.

SEATS

  • Wide, flat seating surfaces tolerate minor damage that can easily cause leakage in valves that utilize line contact seating.

APPLICATIONS

  • Main Steam Isolation
  • Hot Reheat Isolation
  • Other combined cycle, critical, super-critical, and ultra super critical steam applications.
