The loading valve and pressure gauge allow a progressive buildup… $1,892.00 – $2,130.Hedland offers a complete line of over 15,000 variable area flow meters to measure oil, phosphate esters, water and water-based fluids, as well as air and other compressed gases. Installation is extremely simple, and the test kit can be connected to either the pressure or return lines. The unit is self-contained and requires no electrical power. The kit consists of a direct-acting flow indicator with a built-in thermometer, a loading valve, and a pressure gauge all built into a strong steel case with a removable lid for protection. The RFIK mechanical hydraulic tester offers the perfect solution for troubleshooting and servicing hydraulic systems on agricultural and other mobile machinery. An analog flow indicator with an integrated load valve and an analog pressure gauge in one compact unit is perfect for testing hydraulic pumps without removing them from service. Consequently, to prevent unnecessary downtime it is vital to check the efficiency of hydraulic pumps on a routine schedule. The volumetric efficiency (internal leakage) of hydraulic pumps will increase with age. HydraCheck’s exclusive integral safety relief valve prevents an overpressure condition when testing hydraulic components by allowing the oil to bypass the load valve at a pre-determined set pressure. Using a load-cell without a safety relief valve exposes the user to an extremely hazardous situation if the load-cell blocks the discharge flow from the rod-end of the cylinder and causes pressure intensification. This problem also applies to testing single-rod, double-acting cylinders. In this case, if the load cell does not contain a safety relief valve, the user is exposed to a hazardous situation. at the inlet port of the directional control valve. This unique feature removes the risks typically associated with testing fixed-displacement pumps and single-rod, double-acting cylinders.įor example, in a fixed-displacement pump application, the pressure relief valve is typically located at some distance from the pump, e.g. HydraCheck adds versatility to its range of inline flow meter test kits by adding a safety relief valve to the load-cell.
