Shanghai Hongba Soft-sealed Butterfly Valve with Electric Actuator, Model D941X - 16C, DN65, widely used in industrial pipeline control, boasts unique operational advantages.
This butterfly valve features a simple structure, with the characteristics of compact size, light weight, and relatively low cost. This property is particularly prominent in气动hard-seated butterfly valves. It is suitable for installation in high-altitude tunnels and other special locations, controlled by a two-way five-way solenoid valve, offering convenient operation and the ability to adjust the flow medium.
From a hydrodynamics perspective, it has lower fluid resistance. The large-diameter pneumatic butterfly valve has a larger effective flow area when fully open, allowing the medium to pass through smoothly. Its opening and closing action is quick and effortless, requiring only a 90° rotation of the butterfly plate to complete the operation. Due to the nearly equal medium force acting on the butterfly plates on both sides of the shaft, the torque directions are opposite and cancel each other out, resulting in a smaller closing torque. Under low-pressure conditions, this butterfly valve can still achieve a good sealing effect. It offers a variety of sealing materials, including nitrile rubber, fluoroelastomer, edible rubber, and PTFE lining, ensuring excellent sealing performance. Among them, the hard-sealed butterfly valve uses a soft-hard layered metal sheet, combining the dual advantages of metal hard sealing and elastic sealing, maintaining outstanding sealing performance under various conditions, including low temperatures.
The electric soft-seated butterfly valve has its blade mounted in the diameter direction of the pipeline. Within the cylindrical passage of the butterfly valve body, the circular disc blade rotates around the axis, with a rotation range of 0° to 90°. When the blade rotates to 90°, the valve is fully open. The entire valve consists of only a few parts, featuring a simple structure and easy operation, achieving quick opening and closing with just a 90° rotation. Additionally, the electric valve boasts excellent fluid control characteristics. When the butterfly valve is fully open, the thickness of the blade acts as a resistance for the medium flowing through the valve body, resulting in minimal pressure drop, thereby providing good flow control properties. Butterfly valves come in two sealing types: elastic and metal. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the blade, ensuring a reliable sealing effect.
Product Features:
1. This valve features a vertical plate structure with a sealing function that becomes tighter with each closure, ensuring reliable sealing performance.
2. The sealing pair material is paired with stainless steel and nitrile oil-resistant rubber, offering a long service life.
3. The rubber sealing rings can be positioned on either the valve body or the butterfly plate, accommodating various media characteristics for user selection.
4. Butterfly valves are designed with a framework structure, featuring high strength, a large flow area, and low flow resistance.
5. Overall baked paint finish, effectively prevents rust and can be used for different mediums with just a replacement of the sealing valve seat seal material.
6. This valve features bidirectional sealing, allowing for installation without being controlled by the medium's flow direction or affected by the spatial position, and can be installed in any direction.
7. This valve features a unique structure, offering flexible operation, ease, and convenience.
