It can be equipped with a head with electric signalling contact (IP 300), with or without a Visual indicator. A special version (IP 210), equipped with a faucet on the body, allows disassembly and reassembly of the pressure mechanism. It can also be equipped with an extension cord for buried pipes. The basic model (IP 200) is bidirectional and is equipped with a red Visual head. They can be used for the entry and exit of scrapers.
