772200 electrically controlled fuel valve

772200 is an electrically controlled fuel valve used in aircraft and technical fuel systems for remote opening and shut-off of fuel lines. The unit is intended for operation with aviation fuels and receives an electrical command from the aircraft control circuit to change the fuel flow state. In the passport, the product is named as an electrically controlled fuel valve, designation 772200, with passport 772200 PS. The unit may also be described in catalog references as a fuel valve or electrically controlled fuel shut-off valve.

Fuel shut-off function of 772200

The 772200 valve provides remote control of fuel flow in aircraft fuel lines. Depending on the command from the onboard electrical system, the valve opens or closes the fuel passage and allows the system to route, isolate or stop fuel flow through the required section of the fuel system. This function is used where manual access to the valve is limited or where centralized cockpit or system-level control is required. The valve is intended to work in fuel and fuel-vapor environments, while the electromechanism operates in air.

772200 operation in aviation fuel systems

The 772200 unit is designed for fuel systems using aviation fuels such as RT, T-1, TS-1, T-2, T-6, T-7AP and related fuels specified in the product passport. The valve is suitable for operation across a wide temperature range and under defined fuel pressure conditions. It supports high fuel flow through the unit, making it suitable for large aircraft fuel systems and technical installations where controlled opening and closing of fuel lines is required. Correct operation depends on fuel cleanliness, electrical supply condition, sealing and actuator serviceability.

Installation context of the 772200 fuel valve

The 772200 electrically controlled fuel valve may be used in aircraft fuel systems, aviation technical equipment and specialized fuel-system installations. Application references include fuel systems of heavy transport aircraft and systems associated with Object 86 and D-30KP-2 engine installations, depending on the applicable documentation. In aircraft fuel tanks, the valve body may be installed in the fuel path, while the electrical actuator is kept accessible from the outside side of the tank or structural wall. Exact installation must be confirmed by aircraft fuel system documentation.

Construction and delivery set of 772200

The product is supplied as an electrically controlled fuel valve assembly. According to the passport completeness section, the delivery set includes one electrically controlled fuel valve 772200 and one passport for the MVD4E 15B electromechanism under designation 8A4.030.177-01PS. The passport also notes that additional delivery-set information is not provided. Material content listed in the passport includes aluminum and copper. These details are useful for identification, acceptance and warehouse processing of the unit.

Identification and ordering of 772200

Before ordering 772200, the buyer should confirm the aircraft or system type, required condition, serial number, documentation set and completeness of the electromechanism documentation. The unit may be requested for fuel system repair, overhaul support, replacement stock or restoration of aircraft fuel equipment. For acceptance, it is useful to request the product passport, test or inspection records, confirmation of operating medium, pressure range, power supply and actual mass. Since the valve may be used in safety-related fuel circuits, compatibility should always be checked against the aircraft documentation.
