HILCO Butterfly Valves
HILCO 3-Way & 6-Way Butterfly Valves
Butterfly Valves Engineered for Large Diameter Duplex Filtration Systems
HILCO 3-way and 6-way butterfly valves provide a practical alternative to traditional transfer valves in large diameter piping systems. Designed primarily for applications utilizing 6-inch and larger piping, these valves simplify system operation while maintaining reliable flow routing for duplex filtration and fluid management systems.
By mechanically linking multiple butterfly valves into a single assembly, HILCO butterfly valves allow operators to perform system changeovers with a single actuation point, reducing effort and improving operational efficiency.

HILCO Butterfly Valve Key Features:
Optimized for Large Diameter Piping
Designed specifically for applications requiring 6-inch and larger piping, HILCO butterfly valves reduce the operating force typically associated with large transfer valve assemblies.
Simplified Valve Actuation
A custom-engineered lever handle helps reduce operator effort during valve actuation, making routine filter changeovers faster and easier.
Adjustable Linkage Design
An adjustable linkage system allows operators to fine-tune valve alignment, helping maintain proper sealing and minimize leakage throughout the service life of the valve.
One Person Operation
Two mechanically linked butterfly valves allow the assembly to be actuated through a single operating handle, enabling one person to perform valve changeovers.
HOW IT WORKS
Coordinated Valve Positioning Across Multiple Flow Paths
Designed for applications utilizing 6-inch and larger piping, HILCO Butterfly Valves combine multiple butterfly valves into a mechanically linked assembly operated through a single actuation point. This coordinated design allows multiple flow paths to be changed simultaneously, helping simplify system operation and reduce operator effort during valve changeovers.

HILCO Butterfly Valves help deliver:
Reduced Actuation Effort
Custom-engineered lever handle helps simplify valve operation.
Improved Operational Efficiency
Single actuation point streamlines system changeovers.
Enhanced Leakage Control
Adjustable linkage design allows operators to fine-tune valve alignment.
One-Person Operation
Mechanically linked valve design reduces manpower requirements for valve actuation.
By combining large diameter butterfly valves into a single coordinated assembly, HILCO Butterfly Valves help simplify operation, improve efficiency, and support reliable fluid routing throughout the system.
