Plastic Lined Butterfly Control Valve: Durable Precision for Corrosive Environments
Introduction
We are a leading control valve manufacturer in China, delivering high-quality valves and control actuators engineered to meet a wide range of industrial applications.
Plastic lined butterfly control valves are engineered for exceptional performance in harsh industrial environments. By integrating advanced sealing technologies with a unique triple-eccentric design, these valves deliver precise flow control, extended service life, and minimal operating torque. The combination of soft sealing, hybrid soft-hard multi-level sealing, and full metal sealing options makes them highly adaptable to a wide range of media and temperature conditions.
Designed with energy efficiency and durability in mind, especially in corrosive and high-pressure settings, plastic lined butterfly control valves offer a reliable, leak-free, and cost-effective solution across industries such as chemical processing, power generation, and water treatment.
Available in sizes from DN15 to DN1000, these valves support multiple pressure ratings to suit global system requirements:
PN6, PN10, PN16
ANSI Class 150, 300, 600
This ensures seamless integration into diverse pipeline systems, from compact installations to large-scale industrial networks.
Plastic lining materials such as F46 (PTFE) and PFA provide robust protection against aggressive media, including strong acids, alkalis, and oxidizing agents.
Valve body materials include:
WCB (carbon steel)
CF8 (304 stainless steel)
CF8M (316 stainless steel)
These options ensure optimal performance based on the application’s corrosivity and mechanical demands.
Meeting ANSI B16.104 Class VI leakage standards, the valves ensure tight shutoff in applications requiring absolute sealing integrity. Metal sealing options—available for high-pressure, high-temperature conditions—comply with Class IV or Class V leakage classifications.
The three-eccentric structure minimizes contact between the disc and seat during operation, resulting in:
Reduced friction and wear
Stable, low-torque operation
Quick opening and equal-percentage flow characteristics
This design supports both on-off and throttling functions with high reliability.
With a control ratio of up to 100:1, the valves deliver precise flow regulation for complex process applications such as:
Dosing and metering systems
Multi-phase flow control
Chemical injection and blending
Equipped with sealing materials such as PTFE, RTFE, or flexible graphite, the valves ensure low fugitive emissions and excellent performance across wide temperature ranges:
Standard operation: -30°C to 150°C
Optional design: -40°C to 570°C
Low Torque Operation: The eccentric mechanism lowers actuation requirements, reducing costs for automation and manual operation.
Compact and Lightweight: Ideal for installations in tight spaces without compromising durability.
Global Standard Compliance: Flange connections meet GB/T 12221-2005, ASME B16.10, API 609, and ISO 5752 standards.
Multiple End Connections: Offered in RF (raised face), RJ (ring joint), FM (flat face), lug, and wafer types to suit diverse piping configurations.
Wide Media Compatibility: Effective for water, steam, oil, gas, air, and various chemical fluids.
