The gate valve with grooved ends and position indicator fits the quick clamp system and are machined according to AWWA C606. The grooved valve ends are fixed to the pipe material – e.g. steel or cast iron – by means of standard clamping couplings.
Over the past 75 years, the grooved end clamping system has proved to be one of the fastest and most efficient ways of joining pipes due to its high degree of flexibility. Furthermore, it absorbs vibrations and noise transmission through the system. It has a certain degree of angular deflection of the pipe joints and alignment in all positions 360° around the pipe axis. Therefore, the system has gained a footing in high rise buildings where vibrations and stress of pipe systems are significant.
The grooved end gate valve is a further development of the well-known VdS-approved gate valve which was originally designed for sprinkler systems. This industry has recognised the time saving and effective way to connect pipes and fittings.
AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water approved EPDM rubber compound. It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The triple safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.
