Manual Flange Butterfly Valve With Handwheel
Manual flanged butterfly valves are known for their compact design and light weight. They are easy to operate with just a 90° turn and require minimal torque. Their design allows for easy disassembly and maintenance, making them versatile for various installations.
The sealing structure features a composite seat of PTFE, synthetic rubber, and phenolic resin for high strength and elasticity, ensuring superior sealing performance. The fully PTFE-coated butterfly plate offers excellent corrosion resistance, while the pinless design eliminates leakage points, enhancing reliability.
These valves have near-linear flow characteristics for precise flow control and a spherical butterfly plate shape that improves sealing and extends service life. Replaceable seals and customizable claddings for corrosion and abrasion resistance ensure long-term durability in diverse environments.
Model: Manual Flange Type Valve
Size Range: 2″ to 40″
Pressure Range: 1.0 to 1.6MPa
Material : Cast Iron, Cast Steel, WCB, Stainless Steel
Features
- Compact design: Compact, lightweight, easy to install and maintain, improving the efficiency of operation and maintenance.
- Easy operation: Only need to rotate 90 ° can be quickly opened and closed, low torque, easy to operate.
- Corrosion resistance: The butterfly plate is coated with PTFE material, which has excellent corrosion resistance and is suitable for various environments.
- High durability: The pinless connection design between the butterfly plate and stem eliminates the possibility of internal leakage and improves the reliability and durability of the product.
- Outstanding Flow Adjustability : Long service life: the spherical butterfly plate improves sealing performance and prolongs valve life, maintaining zero leakage even after opening and closing the valve more than 50,000 times.
- Easy maintenance: The seals can be modified according to the needs of different working conditions, and can be sprayed with various coatings according to the user’s requirements to improve corrosion and abrasion resistance.
