630600

Operating principle of 630600

The shut-off member moves between the open and closed positions and either provides the specified flow section or seats to stop the fuel stream. The actuation method and travel limits must match the installed control linkage. Reliable operation depends on clean working fluid, the moving element, seat, springs and seals. Contamination, reversed connections or an unsuitable pressure can prevent the intended response.

Role in the aircraft system

Aircraft fuel system; technical listings identify 630600 as a through-flow shut-off valve and Mi-24 fuel-system material includes this designation. The exact installation point depends on aircraft modification. The valve works with pipelines, a pressure source, downstream equipment and the control elements of its circuit. These products are functionally related but must not be described as interchangeable merely because they operate in the same system.

Installation and maintenance checks

Before installation, verify the nameplate, ports, flow direction, internal cleanliness and seal condition. Working pressure, temperature, fluid and the prescribed functional test must come from the passport and maintenance documentation. Adjustment without approved instructions is not permitted. Incoming-inspection results should remain with the product records.

Identifying 630600 for ordering

Confirm designation 630600, port orientation, actuator interface and fuel compatibility. Similar 629600 and 633600 series products perform different hydraulic or fuel-system functions. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
