www.valvetests.com JLD series hydraulic valve test bench is a set of mechanical, hydraulic, pressure test liquid media storage cycle used in one, with perfect function, stable performance, high degree of automation. Pressure test process consists of hydraulic transmission, electrical control, on the tested valve applied without any additional influence the test results and external force, widely used in nominal diameter DN50-DN3000mm flange type, on the folder type structure, high, in, the low-pressure valve, wafer type check back valve, knife type valve, the valve seal and strength etc. the performance test. Highest sealing test pressure 10.0MPa, strength 16.0MPa. JLD type hydraulic butterfly valve test bench, used to test the valve flange end face to do the positioning and sealing, by the hydraulic cylinder reciprocating drive work to carry out the work of pressing. In order to minimize the impact of external pressure, the pressure cylinder output pressure in the (3.0-30.0MPa) pressure level to control the choice of pressurization, so that the valve under different sizes and pressure to carry out the valve test. Multi axial pressing oil cylinder only radial move forward and backward, has been to use reciprocating cylinder drive, a connecting rod mechanism of the transmission of the multi axial clamping oil cylinder move synchronously.
