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.
