RPM Portable Valve Gearboxes for underground valves

riduttori

Scapin’s brand new RPM Portable valve gearboxes for valve operators are specifically conceived and designed to perform easy and fast opening/closing of underground water valves, both manually or coupled with our APB/APS portable valve actuators.

RPM tools are the ultimate devices for operating on underground valves not equipped with a reduction gearbox and usually moved using a T-Key, valves that require Nm/Ft lb values higher than manual work of one single operator, or when a valve requires a high number of turns to be fully open or closed.

Thanks to their light weight, RPM tools can be easily transported and mounted on intervention site. Locking system of pedestal avoids ‘snatch’ rotation of RPM device while operating and prevents risks of injury to operators.

RPM devices available are RPM100N (reduction ratio 1:1) for operating on underground valves up to 100Nm / 73,76 Ft lb, and RPM300N (reduction ratio 4,5:1) for moving valves up to 300Nm / 221,27 Ft lb.

Each RPM device is composed of two different parts: the Basic Pedestal (a portable tripod of 600mm / 23,62'' height provided with fixing brackets and sleeve anchors) and the Gearbox set. This one is furnished inside a handy plastic case and contains gearbox reducer, telescopic shaft and all remaining articles for mounting RPM device. A set of accessories that includes extensions for shaft and pedestal, adaptors and bushings (visit Bushings on Portable Actuators section) are available to allow installation and usage of RPM tools on sites of several sizes and shapes.

RPM devices guarantee high performances when used coupled with an APS portable valve actuator, allowing to open/close underground valves up to 300N / 221,27 Ft lb in less time than manual movement of one (or more) operator, and with no physical effort required.
