The quality of the water we consume daily or use in industrial processes directly depends on the quality of the infrastructure that transports it. Outdated steel pipes or plastic materials of questionable quality can compromise not only water pressure but also its sanitary quality. This is where the VALWater system developed by Valrom Industrie comes in.
What is the VALWater system?
VALWater is the complete solution designed for pressurized cold water supply networks. At the heart of this system are High-Density Polyethylene (HDPE) pipes (technically known as PE80 and PE100). These materials are globally recognized for their superior properties in transporting pressurized fluids.
Major advantages of VALWater HDPE pipes
-
Chemical and sanitary inertia: VALWater pipes do not alter the taste, smell, or composition of drinking water. Unlike metal pipes, polyethylene does not rust and does not promote the formation of limescale deposits on the inner walls.
-
Flexibility and shock resistance: The ground moves, whether due to heavy traffic, seismic activity, or freeze-thaw cycles. The flexibility of VALWater pipes allows them to absorb these stresses without cracking, an enormous advantage over traditional rigid piping.
-
Impeccable jointing systems: Watertightness is guaranteed by using compression fittings (for small and medium diameters) or by butt welding and electrofusion technology (for main networks).
From residential projects to public infrastructure works
The VALWater range is extremely versatile. We offer solutions starting from small diameters (20mm), perfect for individual house connections, up to large diameters (up to 1200mm) intended for urban infrastructure. Each product is marked according to international standards, guaranteeing safe working pressures (PN6, PN10, PN16).
Frequently Asked Questions (FAQ) – VALWater
1. Can VALWater pipes be installed above ground, exposed to the sun? Black polyethylene pipes with a blue stripe (specific for water) contain carbon black additives that provide good resistance to UV rays. However, for maximum lifespan, we recommend burying them below the frost line (usually 80-90 cm in Romania).
2. How long does a buried VALWater HDPE pipe last? Under normal working pressure and temperature conditions, a correctly installed network using VALWater HDPE pipes has an estimated lifespan of over 50 years.
3. Do compression fittings require special tools for installation? For common residential diameters (e.g., 20mm – 32mm), VALWater compression fittings can be tightened even manually or using standard fitting wrenches, making installation extremely fast and intuitive, with no welding required.
4. Are VALWater products safe for drinking water? Yes, all components of the VALWater system that come into contact with the fluid hold sanitary approvals and quality certifications that attest to absolute compliance for drinking water transport.
