Product Description

Most wafer-style butterfly valves are engineered with four holes that align with the connected pipeline. The valve is designed to clamp between two flanges in your pipe work. Most wafer butterfly valves fit the majority of flange standards. The rubber or EPDM valve seat creates an exceptionally strong seal between the valve and flange connection.

Unlike lug-style butterfly valves, wafer-style butterfly valves cannot be used as pipe ends or end-of-line service. The entire line must be shut down if either side of the valve requires maintenance. Wafer style butterfly valves are manufactured to be compatible with either pneumatic or electric actuation. Disc and seat material should be determined based on application and flow media.

• Upper and Lower Bearings to maximize valve life
• Direct Mount
• 2"-12" standard with lever
• 14"and larger standard with gear
• Support shaft seal: bonding of elastomer to phenolic backing ring protects against distortion, a common cause of shaft leakage
• Integral ISO mounting pad for easy valve operation; no bracket needed
• One piece stem ensures dependability and positive disc positioning
• Available in Wafer and Lug styles
• Disc has a precision profile that provides bubble tight shut off and assures minimum torque
• Seat Materials: Multiple seat materials available
• Seat Face negates need for flange gaskets
• O-Ring ensures dependability and positive disc positioning
• 2"- 12" 200 psi
• 14"- 24" 150 psi

Wafer butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points.They provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary.

These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.

When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.

Industrial Applications

Butterfly valves are used in a variety of industries, including:

• Oil and gas
• Chemical processing
• Water and wastewater processing and transportation
• Food processing
• Pharmaceuticals
• Manufacturing
• Shipbuilding and shipyards
