Insta-Valve Plus Valve Installation

Hydra-Stop’s Insta-Valve Plus installation provides a means to install a permanent valve into a water main without interrupting flow through the pipe and without reducing line pressure (up to 150 psi). The insertion of an Insta-Valve Plus installation is accomplished by using tried and true tapping techniques (under full line pressure) with no reaming or excessive pipe strength loss. The Insta-Valve Plus valve installtion permanently remains in the water distribution piping to allow system repair in the same manner as any gate valve which would have been originally installed with the water main.

The award-winning Insta-Valve Plus valve installation, from Hydra-Stop®, is a resilient seat valve that uses bullet stopper technology to stop flow in all types of pipe, and can be installed under pressure, up to 150 psi. The Insta-Valve Plus valve installation exceeds industry standards and provides a safer, more economical way of inserting valves in your system. The Insta-Valve Plus is easy to use and even easier to install. They install in half the time, without service disruption, providing immediate system control with only one cut.

The Insta-Valve Plus design includes the industry standard bronze stem collar and a heavy duty valve stem for the strongest of valve operators. Insta-Valve Plus stops flow in all types of pipe, 4” to 16”; including potable water mains, wastewater force and gravity mains, and industrial applications. It can be installed using existing Hydra-Stop equipment or as a stand alone system.

The sealing surfaces of the Insta-Valve Plus consist of a compression molded contour seal joined to the radial axis sealing area that optimizes the seal on both the pipe and the location where the coupon is removed.
