Description
The Väli VPWS 450 is an automatic butt fusion machine for thermoplastic pipe from 200 mm to 450 mm. It is the first model in the VPWS automatic range to use a 380 V three-phase supply, with a total power of 8.38 kW.
It has an electrohydraulic control unit, a removable PTFE-coated heating plate, a removable electric facing tool and an electronic countdown timer.
Key Features and Benefits
Three-phase supply
The machine operates on 380 V, 3-phase, 50/60 Hz.
Large-pipe range
Eight sizes run from 200 mm to 450 mm, for HDPE, PE, PP and PVDF pipe.
Heating plate
The removable PTFE-coated plate has electronic temperature control up to 270°C with a deviation of less than ±7°C.
Pressure and timing
The hydraulic unit adjusts pressure from 0 to 8 MPa, and an electronic countdown timer handles the heating and cooling times.
Facing tool
A removable electric facing tool prepares clean, parallel pipe ends before welding.
Applications and Use Cases
The Väli VPWS 450 is used for:
- Water supply and distribution networks
- Municipal sewage and wastewater systems
- Industrial pressure pipelines
- Large irrigation systems
