The valve life test bench is a highly automated high-performance testing equipment designed to simulate the repeated opening and closing operations of valves under actual working conditions, in order to evaluate their durability, reliability, and overall performance degradation trends. This device accurately measures and records changes in valve sealing performance, operating torque/thrust, and wear of key components through tens of thousands or even millions of cycles of testing, in order to determine the service life and failure mode of the valve. It is a key equipment for valve manufacturers to conduct product research and development, quality certification, and supplier evaluation for high-end users. The equipment simulates the working cycle of valves in real environments through a precise electromechanical hydraulic integrated system.

The valve life test bench is not just a simple “fatigue testing machine”, it is a comprehensive valve reliability verification platform. It uses scientific accelerated experimental methods to concentrate the aging and wear that valves may experience in the coming years or even decades into a few weeks or months. This investment has irreplaceable strategic value in enhancing the core competitiveness of valve products, winning the trust of high-end markets, and ensuring the safety of major projects.

Technical performance and feature

◆The system is made up of “industrial touch screen computer”、 “pressure sensor”、 “torque sensor”、 “angular dispalcement sensor””PLC、 “conversion module”、”switch power”、”printer” and “industrial control configuration software”;

◆The system can have the following automatic cycle life test on valve with pressure:”valve pressurize —— close with pressure —— one enddischarge sealing pair with full pressure-—open valve with pressure——valve pressurize… ..”‘\

◆You can choose any type pf “torque control”、 “stroke position control”、 “torque control + stroke position control valve opening and closing inthe system (you only can choose”torque control” to control some types of valves opening and closing);

◆The system has automatic cycle test according to pre-set number of automatic cycle and stop automatically, system record total cyclenumbers and each round of opening and closing torque value;

◆System can test valve opening and closing torque value seperately, testing result can be saved and printed out in digital and image curve;

◆The system real-time monitor all datas during testing process, display and save it in the system. You can be access、 retrieve and print outhistorical testing data (including curve graphical data) by keyword, provided the conditions for subsequent quality issuesretrospective.Testing data can be exported to Excel and realize ERP management for customer. Testing data can be output through “UsB”interface or network cable.

◆Customer can select the following models of valve life test bench and configuration:

Hold pressure valve life test bench (suitable for flanged end valves) (Model:YFB-SM/※ ※);

Top press valve life test bench (suitable for groove welded、 flanged end valves) Model:YFB-SMDY/※ ※) ;

Top screw valve life test bench (suitable for inner tunnel sealing valves);(Model: YFB-SMDL/※ ※);Safety door.
