Product Detail

Wafer Valve For Sale – UD Series Hard-Seated Butterfly Valve

The Marine UD Series Hard Seated Butterfly Valve differs from the soft sleeve type in several ways.

Firstly, the hard-seated wafer valve does not utilize a soft sleeve for sealing. Instead, it features a durable, rigid seat material, such as phenolic-backed or aluminum-backed seats. These seats are non-collapsible, stretch-resistant, and blowout-proof, providing reliable sealing even under high-pressure conditions.

Secondly, the installation process differs. The hard-seated wafer valve typically incorporates correcting holes on the flange, allowing for easy correction during installation to ensure proper alignment and positioning.

Thirdly, the maintenance and replacement process is simplified in the hard-seated valve. It can be designed with either a through-bolt or a one-side bolt configuration, enabling easy replacement and maintenance procedures.
