Telescopic housing for core drill NP-1, NP-2 L=1255-1825mm 71.455.1825

Telescopic casing for borehole – a reliable control element for fittings

This telescopic casing, manufactured by BOHAMET-ARMATURA, is a key element enabling remote control of fittings in underground installations. Designed to work with NP-1 and NP-2 boreholes, it provides convenient operation and protection of valves against mechanical damage and weather conditions. Its adjustable length allows it to be adapted to different installation depths, making it a universal solution for both professional installers and end users.

Construction and application

The telescopic casing serves to extend the valve stem in a movable way, allowing control of slide valves and boreholes from ground level. It is used in water supply and sewage systems where remote opening and closing of valves is necessary. Length adjustment in the range of 1255 mm to 1825 mm allows for perfect adaptation to specific mounting conditions, eliminating the need for additional adapters or connecting elements. Made of durable materials, it ensures long-lasting and trouble-free operation even in harsh environmental conditions.
