Application scenarios
Shutoff and maintenance isolation in PE/PP pressure pipelines
Used for fluid shutoff and maintenance isolation in PE or PP pressure pipeline systems, suitable for SDR11, SDR17, SDR17.6 and SDR33 pipes, with a replaceable seat and a removable valve.
Selection points
PE/PP pressure pipe compatibility with no adapter gaskets required
The valve is designed specifically for PE HD and PP pressure pipes and is suitable for SDR11, SDR17, SDR17.6 and SDR33. The product documentation explicitly states that no machining or installation of complex adapter gaskets is required.
Three-bearing valve shaft design against deflection
The valve shaft is fitted with three bearings to prevent shaft deflection. The product documentation states that this design maintains high positioning accuracy even after prolonged use.
Replaceable seat design
The seat is replaceable, making the valve suitable for maintenance concepts in which the seat is treated as a replaceable component.
Large-diameter valve shaft for higher pressure loads
Sizes da400 and above use a single-shaft design; the product documentation states that it is used to withstand higher pressures.
Standardized top flange and face-to-face dimensions
The top flange conforms to EN ISO 5211, and the face-to-face dimensions conform to EN 558 Series 20, ISO 5752 Series 20 and API 609 Table 1.
FAQ
Which plastic pressure pipes and SDR ratings is the Z414-A lugged butterfly valve suitable for?
The Z414-A is designed for PE/PP pressure pipes and is suitable for SDR 11, SDR 17, SDR 17.6 and SDR 33 pipes. Its valve bore matches the requirements of PE HD and PP pressure pipes, avoiding the need for complex adapter gaskets.
How do I select the size range and maximum operating pressure of the Z414-A based on the SDR rating?
For SDR 11 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. For SDR 17, SDR 17.6 and SDR 33 pipes, sizes from da 50 (DN 40) to da 500 (DN 500) are available. Of these, SDR 17 (PE-100) allows up to 10 bar, SDR 17.6 (PE-80) up to 6 bar, and SDR 33 (PE-100) up to 5 bar. Actual selection should be confirmed in relation to the medium, temperature and pipeline system operating conditions.
Which standards do the installation interfaces and dimensions of the Z414-A comply with?
The face-to-face dimensions of this valve comply with EN 558 Series 20, ISO 5752 Series 20 and API 609 Table 1; the connecting flange is EN 1092 PN 10 and the top flange conforms to EN ISO 5211. This combination simplifies installation and configuration with pipelines and actuator interfaces built to the corresponding standards.
Can the Z414-A be installed in any orientation?
Yes. The Z414-A can be installed at any angle. The valve shaft is fitted with three bearings to prevent shaft deflection and to help maintain high positioning accuracy after prolonged use. Sizes da 400 and above use a single-shaft design to withstand higher pressures.
What are the sealing performance, temperature range and maintenance characteristics of the Z414-A?
The Z414-A sealing rating complies with EN 12266 Leakage rate A and ISO 5208 Category 3. The operating temperature range is -10 °C to +160 °C, although the permissible operating conditions depend on pressure, medium and material. The seat is replaceable, the valve is designed to be maintenance-free, and it can be disassembled to support material recycling.
