Housed in a steel white epoxy coated box and a key-operated 90° lock for security with 20,000 lock combinations.
-
Gas Identification is located on the body of the AVSU behind the window and is immovable.
-
A large viewing window to the door gives an immediate indication of Gas Identification located on the body of AVSU, valve position and flow direction.
-
In an emergency, this can be gained by pulling the window thus allowing access to the valve. The anti-Tamper device can be fitted to the window and connected to our Digital Alarm and BMS to incorporate monitoring of all CPX AVSU’s.
-
The valve type is a 90° shut off ball valve, which is operated via a red ergonomic handle, each unit comes complete with a blanking plate which can be fitted, to either side of the valve.
-
Non-interchangeable NIST connectors are fitted upstream and downstream of the valve. Including 100% sealing serviceable non-return valves to allow the pipeline to be pressure tested and provide an easily accessible point for gas sampling.
-
Pressure sensors shall be fitted inside the box to enable local monitoring and servicing via Copper Sensing Pipe.
-
Side entry sizes available 22mm, 28mm, 35mm and 42mm (other entry versions available).
