Atwood & Morrill® and Hopkinsons Forged Parallel Slide Valves
Atwood & Morrill Forged Parallel Slide Gate valves are designed for performance in high pressure, high temperature applications
Atwood & Morrill® 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:
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) – provide superior bonding to the base material and support a longer life
Seats:
Wide, flat seating surfaces tolerate minor damage that can easily cause leakage in valves that utilize line contact seating.
