Rigid extension spindle for Hawle PRO butterfly valve

Extension spindles serve the purpose of operating shut-off valves in underground pipeline construction.

Via the round threaded cover the extension spindle is screwed clockwise onto the round thread (round thread adaptor) of the Hawle PRO butterfly valve.

This has the advantage that the torque is transferred from the coupling socket to the spindle square, making the additional pinning of the coupling socket of the extension spindle and the spindle of the Hawle PRO butterfly valve unnecessary.

Especially in case of cohesive soils care shall be taken that the valve and the extension spindle are properly back-filled with sand to ensure frost resistance.

For operation, operating keys are suitable. Extensions and similar are not permitted.

Telescopic extension spindles for Hawle PRO butterfly valves see model no. 950-00.

Material: Round threaded cover: GJL-250, Hawle epoxy powder coated
Spindle head and coupling socket: GJS-400, bituminized, galvanized
Spindle shaft: steel, galvanized
Pipe sleeve: PE-HD
