Frisch Butterfly Valves and Dampers:  Precision Flow Control for Industrial Applications

Frisch butterfly valves and dampers are engineered to deliver reliable, high-performance flow control across a wide range of industrial processes. Available in a broad selection of types, sizes, and materials, these valves are designed to meet the demands of both standard and extreme service conditions, including high temperature, corrosive media, and tight shutoff requirements.

Butterfly Valve Configurations

Frisch offers one of the most comprehensive butterfly valve portfolios in the industry, including:

• Resilient Seated – Ideal for general-purpose applications requiring bubble-tight shutoff and corrosion resistance.
• Centered Disc – Balanced design for consistent flow control and reduced torque.
• Single Offset – Minimizes wear on the seat, extending valve life.
• Double Offset – Reduces friction during operation, improving sealing and durability.
• Triple Offset – Metal-to-metal sealing for high-pressure, high-temperature, and zero-leakage applications.
• Metal Seated – Designed for abrasive and high-temperature environments.
• Swing Through – Provides precise control in low-pressure systems with minimal resistance.
• Refractory Lined – Specialized for extreme heat and corrosive conditions, offering long-term protection and performance.

Each butterfly valve is available with custom seat and seal configurations, ranging from swing-through designs for low-pressure precision to machined hard-faced seats capable of achieving FCI 70.2 Class V shutoff, ensuring tight isolation in critical applications.

Industrial Dampers

Frisch dampers are built for robust flow control and isolation in air and gas handling systems. Designed for durability and performance, they are available in multiple styles and materials to suit:

• High-temperature environments
• Corrosive or particulate-laden flows
• Large-diameter ducting and process piping

Dampers can be configured with refractory linings, custom actuation options, and engineered sealing systems to meet specific process requirements.
