Butterfly valve with stainless disc, manual actuator and EPDM seal Pn 16

Wafer type cast iron butterfly valves PN 16 with stainless steel disc, manual actuator and EPDM sealing represent a type of pipeline valves, where the closing element is made in the form of a disc that rotates around its axis. This allows the valve to transition from the “open” position to the “closed” position by turning 90°.

Connection type

Wafer connection allows installing butterfly valves between flat flanges without the need for additional gaskets due to the EPDM sealing.

EPDM sealing:

• EPDM material has high chemical resistance to water, steam, weak acids, and alkalis.
• Operating temperature range: from -40°C to +120°C (in some cases up to +130°C).
• It is characterized by elasticity, ensuring a reliable fit of the disc to the body even after multiple opening/closing cycles.

Advantages of butterfly valves with stainless steel disc and EPDM sealing

1. Tightness: EPDM sealing provides a high degree of tightness. This makes such valves ideal for water supply and heating systems.
2. High corrosion resistance: Stainless steel disc provides excellent resistance to corrosion.
3. Easy installation: Wafer connection allows quickly mounting the valve without additional gaskets or complex tools.
4. Cost-effectiveness: Butterfly valves have relatively low cost compared to other types of pipeline valves with similar purposes.
5. Compact size: Small installation sizes make them convenient for use in confined spaces of pipeline systems.
6. Ease of control: Control is carried out using a manual actuator, which allows you to open or close the valve with less effort.

Application areas

Butterfly valves with EPDM sealing are widely used in the following areas:

• Water supply and heating systems.
• Sewer systems.
• Industrial pipelines for transporting water and steam.
• Food production (subject to sanitary standards compliance).
• Firefighting systems due to the quick action of the closing/opening mechanism.
