U407 Angle Check Valve

U407 Angle Check Valve

U407 Angle Check Valves are installed on suction system, fuel lines on top of fuel storage tanks to maintain prime. Models are available with male threaded inlets for connection directly into tank bung fittings or with female inlets for connection to a nipple that is threaded into a tank bung fitting. Single-poppet models can be used in applications where the valve is easily accessible for maintenance and disc cleaning or replacement.

Materials:

Body: cast steel

Surface: electronic Nickel plated

Seal : Viton Cased Oil Seal

Features:

U407 features a spring-loaded poppet and Viton Cased Oil Seal discs to assist in keeping the valve closed when installed in high-vibration areas

The Angle Check Valves are recommended for use on suction lines where the pressure does not exceed 34 ft of head. ( approximately 15 psi.)

Materials is cast steel diffrent with cast iron materials , the body will be more stronger more hermetical more pressure resistance

Used for disel, gasoline, ethanol etc.

100% Factory Tested.

nt, some achievements have applied, such as fingerprinting and iris authentication. Internal & Exterior authentication Exterior authentication refers to IC card verifies the legality of terminal equipment, but internal authentication refers to terminal equipment verify the legality of IC card. Some models of COS have two-way-authentication, in other words, using a command to verify validity of card and terminal interactively. As for internal authentication, terminal firstly readout the serial number of filing card that is exclusive with 8-type. Terminal calculates and generates a random data with 8 types according to serial number acquired. By internal authentication command secret key information and random data are transmitted into IC card. IC card encrypt the random data by employing prescribed secrete key information, and transmit encrypted data back to terminal. Encrypted data is decrypted in terminal, and is compared with previous random data. If there are coherent, the internal a fuel dispenser uthentication has been succeeded. Exterior authentication also is conducted by means of terminal. The process is basically similar fuel dispenser to internal authentication. Secret key is of very importance in authentication process from above introduction. In fact, secret key is memorized in IC card and terminal, free from known by third party. Due to every time authentication has a random number, it is very difficult to decrypt so as to ensure the security and reliability of authentication. Safety report Safety report is one of data protection modes aiming at ensuring reliability and integrality of data, preventing data lost or being modified. Data integrality and confirmation of data resource are realized by Message Authentication Code (MAC), yet data reliability is ensured by means of encrypted d fuel dispenser ata module. Safety report consists of encrypted data and additional code. In order to prevent information exchanged being illegal modification, keeping integrality of data, MAC code should verify information.
