About This Product

Voltite's hydraulic bolt tensioner is a bolting tool designed for bolting on top of equipment. Each tensioner consists of a hydraulic cylinder, bridge, puller, and socket. Interchangeable adapter kits are also available for common hydraulic cylinders that can tighten multiple bolt sizes. Voltite products are designed for use with virtually any flange that meets flange standards ANSI B16.5, Mss SP44, and API 17D. Can accommodate bolt sizes from M20 to M100 (¾” to 4”).

■Features

・1,500 bar MWP​ ・15mm stroke​ - Extremely lightweight design​ ・Quickly removable bridge​ ・It is also possible to have two connections as an option. ・Completely prevents oil leakage with a high-strength seal developed in-house.

■Main benefits

-Easy to install and remove in a short time ・Nitride coating on the surface provides extremely high durability and corrosion resistance. ・High-quality hose joint (coupler) that does not cause oil leaks or high-pressure oil injection accidents. ・By improving and improving each part, troubles such as oil not returning to the pump when hydraulic pressure is released are avoided. ・Lightweight design with consideration for carrying around on site without sacrificing work efficiency ・Can be used in places with limited space such as turbines, pumps, boiler casings, etc. ・Smooth piston operation is achieved by using a composite material for the piston seal. ・All products comply with the European Pressure Equipment Directive (PED) and have obtained the European safety standard CE mark. ・Achieve short delivery times through thorough inventory management
