VALVULAS DE REDUCCION DE LA PRESION. |
| 摘要 |
A pressure reduction valve 2 includes movable means in the form of a second piston 12</> which is activated by a filling nozzle to prevent the flow of fluid between an inlet 8 and a regulating sub-chamber 50 thereby to allow the flow of fluid through the valve between an outlet 10 and an inlet 8. This allows a cylinder to be filled whilst the pressure reduction valve 2 is in situ. <IMAGE>
