What advantages do valves made of polyethylene (PE) have over valves made of cast iron?

Valve applications are becoming increasingly diverse, so technological requirements and complexity are also increasing.

This is why constantly endeavouring to achieve innovations and improvements is essential. Valves made of polyethylene (PE) are part of this technological progress.

In contrast to valves made of case iron, those made of PE can be installed quicker and easier because they are much lighter. This considerably simplifies installation procedures and shortens erection times. Valves made of PE and the pipelines in which they are installed can thus be put into operation again much quicker after a replacement.  Another progressive quality feature based on the material used is corrosion protection.  Polyethylene is a highly corrosion-resistant and dirt-repelling material.  This reduces the costs for maintenance, and failure due to corrosion damage can be ruled out. A valve made of PE thus stands for a longer useful life and lower maintenance costs while maintaining the standard of quality in comparison to customary valves made of cast iron.

Today bob综合体育官网下载 has four types of valve made of PE in its range:

• the bob综合体育官网下载 TERRA® K12 Tapping Valve
• the bob综合体育官网下载 HYDRUS® Underground Hydrants
• the bob综合体育官网下载 FLOWJET® Automatic Air Valve for waste water
• the HADE® Flap Valve
