Application scenarios
Isolation and flow control in PE/PP plastic pressure pipes
The ebro Z411-A is designed for PE/PP pressure pipes and suits SDR11, SDR17, SDR17,6 and SDR33 pipes. It can be used for isolation and flow control in piping systems, with a valve bore that complies with the requirements of the relevant plastic pressure pipes.
Selection points
Bore matching for PE/PP pressure pipes
The valve bore complies with the requirements of PE HD and PP pressure pipes and suits SDR11, SDR17, SDR17.6 and SDR33 pipe configurations.
Connection adaptation without complex adapter gaskets
Designed for PE/PP pressure pipe applications, the valve requires no machining or installation of complex adapter gaskets during installation.
Three-bearing shaft design against deflection
The shaft is fitted with three bearings to prevent shaft deflection and to maintain high positioning accuracy over long-term use.
Single-shaft pressure-bearing design for da400 and above
To withstand higher pressures, sizes da400 and above feature a single-shaft design.
Replaceable seat and demountable design
The valve features a replaceable seat and is demountable and maintenance-free.
FAQ
Which plastic pressure pipes is the Z411-A wafer butterfly valve suitable for?
The Z411-A is designed for PE/PP pressure pipes and suits the SDR11, SDR17, SDR17,6 and SDR33 series. Its valve bore complies with the requirements of PE HD and PP pressure pipes, reducing the need for machining and installing complex adapter gaskets.
How to select the nominal diameter and maximum operating pressure of the Z411-A by SDR rating?
For SDR11 pipes, sizes from da 50 (DN 40) to da 630 (DN 600) are available, with a maximum operating pressure of 10 bar for PE-80 pipes; SDR17, SDR17,6 and SDR33 pipes are available in sizes from da 50 (DN 40) to da 500 (DN 500). Of these, SDR17 PE-100 pipes allow up to 10 bar, SDR17,6 PE-80 pipes up to 6 bar, and SDR33 PE-100 pipes up to 5 bar.
What are the installation orientation and flange connection requirements of the Z411-A?
The valve can be installed at any angle. The connecting flange is EN 1092 PN 10, and the face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20 and API 609 Table 1. The top flange complies with EN ISO 5211.
What are the features of the Z411-A in terms of sealing performance and shaft positioning?
The sealing class of the valve complies with EN 12266 Leakage rate A and ISO 5208 Category 3. The shaft is fitted with three bearings to prevent shaft deflection and to maintain high positioning accuracy after long-term use; sizes da 400 and above feature a single-shaft design to withstand higher pressures.
Is the Z411-A easy to maintain and are its sealing parts easy to replace?
The Z411-A features a replaceable seat design and the valve is designated as maintenance-free; it is also demountable, and the materials used can be recycled. The operating temperature range is -10°C to +160°C, but the actually permitted operating conditions must be verified against pressure, medium and material.
