4” Butterfly Valve, Wafer, 200 Psi, Ductile Iron Body
The 4” Wafer Butterfly Valve from a generic brand uses a ductile iron body rated for 200 psi, offering robust pressure handling for water, irrigation, and industrial piping. Its 10-position handle provides straightforward control, while the square stem enhances torque transfer for reliable stem operation. The wafer style supports economical installation between flanges with compatible gasketed joints, making it a versatile option for mid-range applications.
DERNORD Butterfly Valve With Blue Trigger Handle (4 Inch Tri Clamp)
The DERNORD 4 inch Tri Clamp butterfly valve uses 304 stainless steel construction for the disc and body, designed to fit standard 4 inch Tri-Clamp connections. The blue trigger-style handle offers multiple positions (13 total) for precise flow control, with a temperature range from 15°F to 200°F. This configuration suits sanitary or process piping where a reliable, easy-to-operate valve is required in a clamp-based network.
Butterfly Valve with Trigger Handle, Steel Body (4 inch)
This 4 inch butterfly valve features a powder-coated steel body with a grooved connection for quick integration into compatible piping systems. The included trigger handle simplifies operation, especially in applications requiring rapid on/off control or frequent adjustments. A sturdy steel construction offers strong resistance to wear in moderate-temperature services and general mechanical reliability.
Dixon BBFVW400, Ductile Iron Wafer Style
The Dixon BBFVW400 wafer-style butterfly valve uses ductile iron for durability and Buna-N liner compatible with standard water and industrial fluids. The design is optimized for a wafer connection, providing an economical option for mid-range pressures while offering PTFE bushing guidance to enhance smooth operation over life cycles. Ideal for retrofit and new installations in moderate-temperature, non-corrosive environments.
Dixon BFVL400, Ductile Iron Lug Style
The Dixon BFVL400 lug-style butterfly valve offers 4 inch ductile iron construction with a Buna-N liner and PTFE bushing, designed for threaded lug connections that allow isolation without requiring full bolt-up in one side of a system. Suitable for repair or expansion projects, the lug design helps maintain pipe alignment during maintenance while providing reliable flow control up to 200 psi in typical water and irrigation duties.
DERNORD 4 Inch Tri Clamp Sanitary Butterfly Valve, Pneumatic Actuator
DERNORD’s sanitary butterfly valve combines a 304 stainless steel body with a Tri-Clamp connection and a pneumatic actuator. This single-acting valve provides automated control with an automatic return position, suitable for clean-in-place processes and sanitary pipelines. Operating range covers 0-90 degrees, with an air supply required at 5-7 bar (72-102 psi). This option is intended for high-purity or industrial applications where automation and sanitation are priorities.
Buying Guide: Key Considerations for 4 Inch Butterfly Valves
- Connection Type: Wafer, lug, grooved, or Tri-Clamp. Choose based on installation flexibility, maintenance needs, and compatibility with existing flanges or piping.
- Material and Disc Coatings: Ductile iron offers strength for mid-range services; stainless steel provides corrosion resistance for sanitary or corrosive environments. PTFE liners reduce wear and chemical compatibility concerns.
- Pressure Rating and Temperature: Ensure the valve rating matches the system pressure and operating temperature. Some models support up to 200 psi or higher and temperatures near freezing or above typical room temperature.
- Actuation and Operation: Manual handles are simple and cost-effective; pneumatic or automated options support remote or automated control, especially in process facilities.
- Seat Material and Sealing: EPDM, Buna-N, or PTFE seating influence chemical compatibility and durability. Check fluid compatibility to avoid leaks or premature wear.
- Maintenance and Replacement: Consider ease of disassembly, availability of spare parts, and the expected service life in your application environment.
- Sanitary vs. Industrial: Tri-Clamp or sanitary designs are preferred for food, beverage, and pharma lines due to cleanability, while wafer or lug valves may be suited for water, irrigation, or general industrial uses.
