AVK SERVICE CONNECTION VALVE, POM, PN16
Tensile Pentomech™ couplings for PE pipes, DN25-50

AVK International A/S
Bizonvej 1, Skovby, 8464 Galten, Denmark
POM service connection valve with Pentomech™ tensile resistant couplings. For drinking water and neutral liquids to max. 20°C. Note: The maximum working temperature is set according to the ISO9080 lifetime requirements for PE pipes, and is therefore not the max. temperature for the valve.
The POM service connection valves are fitted with Pentomech™ couplings that offer easy, fast and secure installation. The coupling is designed with an external compression nut, which pre-compresses the conical gasket and tensile grip ring, offering tightness and tensile resistance even at low pressure and on oval pipes and uneven pipe surfaces. Like all AVK service connection valves they are designed with a wedge of low-lead brass vulcanised with drinking water approved EPDM rubber.
| Variant 16/59-010 | |
|---|---|
| Material: | Polyoxymethylene (POM) |
| DN: | DN25 - DN50 |
| PN: | PN16 |
| Closing direction: | Clockwise to Close |
Features
- Friction welded body, bonnet and end adaptors of POM (Polyoxymethylene)
- Wedge of brass CW626N vulcanized with EPDM rubber – both brass and rubber certified for use in contact with drinking water– and shaped with guides and a special rubber profile ensuring low closing torques
- Stem of stainless steel with rolled threads providing high strength
- Stem sealing with NBR wiper ring and two EPDM O-rings
- Friction ring between bonnet and thrust collar and a notch in the stem prevent overtorque of the valve
- The Pentomech™ coupling is fitted with an external compression nut and thrust ring of polypropylene, a conical gasket of EPDM and a tensile grip ring of POM. The design is tested and certified by DVGW, Kiwa, NF and WRAS
- Note: The maximum working temperature of 20°C is set according to the ISO9080 lifetime requirements for PE pipes. For higher working temperatures expect a reduction of the PE pipe’s lifetime. Please refer to the local pipe manufacturer for further information.
