BRA.J9.120 - WAFER J9 butterfly valves - stainless steel disc
This category contains interflange shutters of the WAFER J9 type, designed for use in heating, ventilation, air conditioning, and compressed air systems. These valves feature a stainless steel disc and EPDM sealing material, ensuring reliable sealing properties. They operate within a temperature range of -10°C to +120°C and are suitable for potable water applications under Czech regulatory standards.
The valves are constructed from ductile iron (GJS 400-15) and include a lockable operating lever for secure positioning. They are compatible with flange ratings PN 6, PN 10 and PN 16 as per EN 1092. Available in nominal sizes from DN 25 to DN 300, these shutters are ideal for integration into closed-loop systems such as district heating, building services, and pressure air networks.
How to choose
- Select the appropriate DN size based on the nominal diameter of your piping system (e.g. DN 100, DN 150, DN 300).
- Ensure the flange rating matches the system requirements (PN 6, PN 10 or PN 16).
- Verify the operating temperature range (-10°C to +120°C) is suitable for the application.
- Confirm compatibility with potable water if required by local regulations.
- Check the maximum working pressure of 16 bar is sufficient for the system conditions.
