Wafer Style Gear Op Butterfly Valve

Quarter-turn shutoff for large-diameter lines. This ductile iron butterfly valve provides reliable shutoff and flow isolation on large water, HVAC, and industrial piping systems — where a ball valve would be impractically large and expensive. Wafer-style body for compact, lightweight installation between flanges.

• Quarter-turn operation — fast open and close on large lines
• Wafer-style — compact between-flange installation
• Gear operator for easy operation on larger sizes
• Ductile iron body for strength and durability
• Elastomeric seat for bubble-tight shutoff

Overview

Wafer Style Gear Op Butterfly Valve is a ductile iron butterfly valve for shutoff and isolation on large-diameter water, HVAC, and industrial piping systems. Butterfly valves are the standard choice for 2" and larger lines where the cost and space requirements of a ball valve are not practical. Wafer-style body installs between standard flanges for a compact, lightweight installation. Gear operator provides mechanical advantage for easy operation on larger sizes.

Common Uses

• Large-diameter water main shutoffs and isolation
• HVAC chilled water, heating water, and condenser water lines
• Fire protection system isolation valves
• Industrial water and process fluid shutoffs
• Municipal water distribution and treatment

Key Features

• Ductile iron body — high strength, corrosion-resistant
• Elastomeric seat — bubble-tight shutoff
• Wafer-style — lightweight, compact, low cost
• Gear operator for easy manual actuation on larger valve sizes
• Quarter-turn — fast operation, clear open/closed position

Frequently Asked Questions

What is a butterfly valve used for?

Butterfly valves provide quarter-turn shutoff and isolation on large-diameter water, HVAC, and industrial piping where ball valves are impractical in size and cost.

Lug style vs. wafer style — what is the difference?

Lug-style valves have threaded inserts that allow them to be bolted between flanges and support dead-end service. Wafer-style valves are clamped between flanges and are lighter and less expensive but cannot support dead-end service.

What sizes are butterfly valves available in?

Butterfly valves are typically available from 2" through 24" and larger for industrial applications.

Do butterfly valves require a gear operator?

Smaller sizes (typically 2"–4") use lever handles. Larger sizes (6" and above) typically use gear operators for practical manual operation.

Why Contractors Choose This Product

• Quarter-turn operation on 4"–12" lines is far faster than multi-turn gate valves during emergencies
• Wafer-style is the economical choice when dead-end service is not required
• Ductile iron body handles the pressure and mechanical stress of large commercial and industrial water systems
• PVFPro stocks lug and wafer styles in the full range of commercial sizes
