The Bevel Gear Actuator for Horizontal Insta-Valve Installation

The Bevel Gear Actuator is the solution to utilizing the Insta-Valve 250 insertion valve in shallow bury applications.

If you have ever wanted to utilize an insertion valve on water mains which are uncontrolled due to broken or missing valves and are also too shallow to utilize a vertically mounted insertion valve, then the Bevel Gear Actuator is your answer.

Available in two sizes — one for 4–8-inch Insta-Valves and the other for 10–12-inch Insta-Valves — the Bevel Gear Actuator can be installed on lines as shallow as 12-18 inches and enables easy operation. Simply align the gearbox hole with the Insta-Valve valve stem and slide into place. Secure the Bevel Gear Actuator to the Insta-Valve with four flange bolts. Install the operating nut and installation is complete.
