Boltight pressure relief safety valves fitted to air pumps minimize risk of equipment failure during bolt tensioning, it’s announced.
The integral tamperproof valve is fitted to the high-pressure unit. It helps avoid incorrect use of bolt tensioning equipment or inadequate training. These can sometimes lead an operator to unsafely build up excess pressure in the system when manually tensioning a bolt to precise measurements.
With the valve fitted, pressure cannot increase beyond a safe operating level. Excess hydraulic fluid is simply routed back into the pump’s oil tank.
Complete pressure valve and tensioning equipment information is available free upon request.
