Description

The Cast Iron Wafer Butterfly Valve is a reliable isolation valve designed for general industrial, commercial, and water service applications. Featuring a cast iron body, ASTM A351 CF8M stainless steel disc, and EPDM seat, this valve provides dependable shut-off performance across a wide range of compatible services.

The valve is supplied with a blue FBE coated body for added protection and durability. Its wafer pattern design is suitable for installation between compatible flanges, including AS 2129 Table D/E and ANSI B16.5 Class 150 flange drillings.

The gearbox operation provides smooth and controlled valve operation, making it suitable for larger sizes or applications where easier manual operation is required. The gearbox also includes a position indicator, allowing the operator to clearly see the valve position.

The valve includes an ISO mounting pad and square stem up to 12″, making it suitable for future actuation where required.

What is a wafer type butterfly valve used for?

A wafer type butterfly valve is used for flow regulation and shut-off in piping systems. Its compact design allows installation between flanges, making it a space-saving solution for water, HVAC, and general industrial applications.

What are the advantages of a gear-operated butterfly valve?

A gear operator provides smooth, controlled valve operation with reduced manual effort. It is particularly beneficial for larger valve sizes or applications requiring precise flow adjustment and controlled opening or closing.

Why is an EPDM seat used in butterfly valves?

EPDM seats offer excellent elasticity and sealing performance, especially in water and air services. They provide reliable, leak-free operation and good resistance to wear, ozone, and many mild chemicals.

What does compatibility with AS2129 Table D/E and ANSI Class 150 flanges mean?

Compatibility with AS2129 Table D/E and ANSI B16.5 Class 150 flanges ensures the valve can be installed in a wide range of pipeline systems. These standards define flange dimensions and pressure limits, ensuring proper alignment and secure bolted connections.

What applications are best suited for cast iron wafer butterfly valves?

Cast iron wafer butterfly valves are commonly used in water treatment plants, HVAC systems, fire protection, and general industrial processes where moderate pressure, reliable sealing, and compact installation are required.
