The wafer butterfly valves have a simple and compact construction, they are small in size and in weight, easy to install and maintain.
The design is made to maintain a seal against bi-directional pressure. There is no leaking under rated pressure.
Suitable medium: fresh water, waste liquid, seawater, vapor, food, medicine, oils, Acids, Alkalis, Salts, etc.
