The U Type Butterfly Valve is a high-performance industrial flow control solution designed for precision and reliability. Featuring specialized U-type flanges, this valve simplifies pipeline centering and ensures a secure, aligned installation. The disc rotates around its axis from 0° to 90°, allowing for rapid transition between fully closed and fully open states, making it ideal for systems requiring quick response times.

Engineered to overcome the limitations of standard wafer designs, the U-type structure reduces the number of connection bolts required under high-pressure and large-diameter conditions. This architectural enhancement significantly increases the structural reliability of the valve and eliminates the negative impact of system weight on operational efficiency, ensuring a long service life and consistent performance in demanding industrial environments.

Frequently Asked Questions

Q: What is the primary difference between U-type and Wafer butterfly valves?

The U-type butterfly valve features integrated flanges that facilitate pipeline centering and reduce the number of bolts needed under high pressure, whereas wafer valves rely on the pipeline flanges for clamping.

Q: Which seat materials are available for aggressive chemicals?

For corrosive or aggressive media, we recommend PTFE or Viton seats, which offer superior chemical resistance compared to EPDM or BUNA-N.

Q: Can U-type butterfly valves be automated?

Yes, they are equipped with ISO 5211 mounting pads, making them compatible with a wide range of pneumatic, electric, and hydraulic actuators.

Q: What prevents internal leakage in the U-type design?

The valve utilizes a pinless structure for the connection between the disc and the stem, removing a common point of potential internal leakage found in traditional designs.

Q: What are the typical pressure ratings for these valves?

Our U-type butterfly valves are available in multiple pressure ratings, including CLASS 125/150 and PN10, PN16, and PN25, to suit various industrial needs.

Q: How does the U-type design affect the installation time?

The integrated U-type flanges significantly reduce installation time by ensuring the valve is automatically centered within the pipeline during assembly.
