Typical Application Scenarios
The rubber lined butterfly valve, also called soft seal butterfly valve, is widely used for cutting and intercepting media such as air, water, steam, corrosive fluids, mud, oil and even liquid metal in pipelines. Below are the most common industrial applications of our wafer end butterfly valves.
HVAC & Building Services
PN16 butterfly valves with EPDM seat provide reliable isolation for chilled water, cooling water and condenser lines in commercial HVAC systems.
Water Supply & Sewage Treatment
Cast iron wafer type butterfly valves are ideal for municipal water distribution, pumping stations and sewage treatment pipelines up to DN1000.
Food, Medicine & Light Industry
Stainless steel body and food-grade rubber seats meet hygiene requirements in food, beverage and pharmaceutical processing lines.
Marine & Sea Water Systems
Al-bronze disc with NBR or Hypalon seat resists sea water corrosion in shipbuilding, offshore platforms and coastal power plants.
Chemical & Petrochemical
Viton and PTFE lined butterfly valves handle acids, alkalis and aggressive chemical media with excellent chemical resistance.
Automated Flow Control
Pneumatic and electric actuated rubber lined butterfly valves support remote operation in automated production and utility networks.
