D371F46-16P/RL stainless steel worm gear lined fluorine butterfly valve (PFA/FEP optional)

D371F46 stainless steel worm gear lined fluorine butterfly valve

This product adopts worm gear transmission, clamp connection, and stainless steel lined butterfly valve structure. The current page diameter is DN40-DN500, pressure is PN16/Class150, the main material is 304 or 316L, and the lining field is PFA/FEP.

What are the functions of stainless steel valve body and lining respectively?

The metal valve body bears the main mechanical load, and the medium side lining is used to isolate the metal from the medium. Even if a stainless steel valve body is used, it is still necessary to choose the appropriate PFA or FEP lining according to the composition and temperature of the medium.

Selection of clamp connection

During installation, the matching flange standard, pressure rating, valve body thickness, and pipeline coaxiality should be checked, and the rotation range of the butterfly plate should be ensured not to interfere with the pipeline.

Is the worm gear butterfly valve suitable for adjustment?

Worm gears can control the butterfly plate to stay at different openings, but the actual adjustment performance still depends on the butterfly plate structure, pressure difference, flow rate, and lining conditions.

Frequently Asked Questions

Can D371F46-16P/RL be directly replaced with the original WCB butterfly valve?

This product is a stainless steel valve body solution, and it is still necessary to verify the matching flange, structural length, pressure difference, lining layer, and contact material. Different valve body configurations cannot be considered as the same supply specification just because the diameter is the same.

Are PFA and FEP the same material?

No, it should be selected separately according to the medium, temperature, and product structure.

Do I need to confirm the butterfly plate space when installing the butterfly valve?

It is necessary to prevent interference between the butterfly plate and the inner wall or adjacent components of the pipeline during the opening process.
