Products Description
Wafer Type Lever Handle Butterfly Valve
This wafer type lever handle butterfly valve is a manually operated wafer-style control valve engineered for fluid shut-off and flow regulation in piping systems. Featuring a compact wafer structure, it can be directly clamped between two pipe flanges without extra flange fittings, perfectly suited for installation sites with limited space. Equipped with an integrated manual lever handle, it allows fast on-off operation and simple flow adjustment by manual control. With reliable performance and cost-effective installation, it serves as an essential component for fire protection, water supply and industrial pipeline systems.
Structural & Operational Advantages
Adopting a slim and lightweight integrated design, the valve occupies minimal installation space and is much lighter than traditional gate valves and globe valves. It is easy to transport, install and maintain on site. The 90-degree rotation opening and closing design delivers smooth operation with low torque. The lever handle can be positioned at any opening degree to stably control pipeline flow. The standard wafer bore matches common flange dimensions, supporting vertical and horizontal mounting without modifying existing pipeline layout, adapting to various construction conditions.
Material Craftsmanship & Sealing Performance
The valve body is made of high-strength ductile iron with precision casting and anti-corrosion surface coating, providing excellent rust resistance and impact resistance for long service life even in humid, outdoor and harsh industrial environments. The precision machined disc cooperates with high-quality EPDM or NBR soft seat to achieve tight bidirectional sealing with zero leakage under low to medium pressure conditions. The sealing material features aging resistance and medium corrosion resistance, compatible with fire water, domestic water and common oil media to maintain stable sealing performance for long-term operation.
Application Scope & Working Conditions
With standard PN10/PN16 pressure rating and complete nominal diameter specifications, the valve adapts to low and medium pressure and normal temperature pipeline working conditions. It is widely applied in fire sprinkler pipelines, building water supply and drainage, municipal water projects, HVAC systems and industrial circulating water pipelines. It can be used as an isolation valve for pipeline section control as well as a regulating valve for daily flow management, ideal for commercial buildings, residential projects and industrial plant piping systems.
