Butterfly Control Valves

Checkbox: Yes

Butterfly valves are compact, rotary-style valves designed for efficient flow regulation and shutoff in a wide range of industrial systems. Utilizing a rotating disk that typically operates within 90 degrees, these valves offer a linear flow characteristic and are ideal for both on-off and throttling applications. High Performance Butterfly Valves (HPBVs)—also known as double offset butterfly valves—have become the industry standard for general service where precision throttling is not required. Their double-offset design improves durability, reduces seal wear, and enhances control in systems with large diameters, high temperatures, or viscous media. With improved flow characteristics and lower installation costs, butterfly valves offer an excellent balance between performance, economy, and reliability.

- Feature Title: Double Offset Design for Longer Life
- Feature Description: The disk moves away from the seat immediately upon opening, reducing friction and wear—resulting in smoother control and extended valve life.
- Feature Title: High Flow Capacity
- Feature Description: With a straight-through flow path and minimal pressure drop, butterfly valves offer exceptional capacity—especially in larger pipe systems.
- Feature Title: Supports Viscous and Solid Media
- Feature Description: Designed to handle challenging process fluids, butterfly valves perform well with thick, dirty, or particulate-laden media.
- Feature Title: Expanded Control Range with Contoured Disks
- Feature Description: Advanced designs feature contoured disks that deliver a near-equal percentage flow characteristic, significantly improving control range and responsiveness.
- Feature Title: Cost-Effective in Large Sizes
- Feature Description: Compared to other control valve types, butterfly valves are a more economical solution for large-diameter and high-temperature applications.
- Feature Title: Multiple End Connections
- Feature Description: Available in wafer, lugged, and double-flanged styles to fit various piping configurations and installation requirements

Butterfly Control Valves

Shut-off safety valves or shut-off valves refer to safety equipment that automatically blocks the flow of gas in the pipeline in case of possible hazards and the gas pressure exceeds the set value through pneumatic actuators.
