High Tech Meets High Performance

Insertion valves are designed to minimise disruption and reduce the cost of system maintenance by as much as 44 percent over traditional shutdown. Hydra-Stop’s 100mm–300mm Insta-Valve 250-UK insertion valves are permanent assets that can be instaled under pressure without system shutdown, and can be used over and over again. And, because they are permanent assets, their costs can be depreciated over time.

Our Insta-Valve 250-UK insertion valves are permanent, resilient, seat-wedge insertion valves that use an engineered, reenforced composite polymer valve cartridge to stop flow in most types of pipe, and can be instaled under pressure up to 17 BAR — without shutdown.

The Insta-Valve 250-UK provides a safer, more economical way of inserting valves into your system. Instaled under pressure, without service disruption, the Insta-Valve 250-UK provides immediate system control. The Insta-Valve 250-UK stops flow in all types of pipe, from 100mm–300mm in diameter, is WRAS BS 6920 1:2000 compliant, and is used in potable water, wastewater and industrial applications.

How It Works

The instalation of a Hydra-Stop Insta-Valve 250-UK valve is accomplished through a single circular hole cut (known as a "tap") under full line pressure into the top of the pipe with no reaming. The Insta-Valve 250-UK insertion valve permanently remains in place allowing for system control and maintenance in the same manner as a resilient seated gate valve.
