Description
KNKE Pneumatic Butterfly Valve Overview
KNKE Pneumatic Butterfly Valves are designed for reliable performance in industrial environments, offering precise control for both on/off and modulating applications. These valves are highly efficient and versatile, making them ideal for industries such as power generation, water treatment, chemicals, and more.
Key Features of KNKE Pneumatic Butterfly Valve
- Compact Design: KNKE valves are small in size, lightweight, and offer low flow resistance, making them perfect for tight spaces.
- Efficient Control: The valves support both on/off and modulating control. With a 4-20mA input signal, they can precisely regulate pressure, flow, temperature, and liquid levels.
- High Durability: Designed for durability, these valves feature a corrosion-resistant construction and use a piston-cylinder actuator for enhanced torque output and reliability.
Superior Performance in Harsh Conditions
KNKE Pneumatic Butterfly Valves are engineered to withstand extreme temperatures and pressures. They are perfect for applications involving air, water, sewage, oil, steam, and gas. Their robust design ensures long-lasting performance, even in demanding environments.
Materials and Construction
- Valve Body: Made from high-quality materials like cast iron, cast steel, stainless steel, and alloy steel.
- Sealing Ring: Options include rubber, PTFE, PPL, stainless steel, and polyamide, providing excellent sealing performance.
- Valve Stem: Constructed from stainless steel or chromium molybdenum steel for added strength and corrosion resistance.
Temperature Resistance of Sealing Materials
KNKE offers various sealing materials suited for different temperatures and operating conditions:
- Chloroprene Rubber (CR): Max temperature of 82°C, min temperature of -40°C.
