Atwood & Morrill and Hopkinsons Forged Parallel Slide Valves

Key features/benefits:

Body: One piece forging minimize material defects and delivers 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) – 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.
