Valve testing the product strength and sealing reliability means: valve testing product for the mobile medium parameter changes, sensitivity to respond accordingly. Test products for the throttle, valve testing products and regulating valve testing products used to adjust the medium parameters of the valve test products, here especially in the safety valve testing, steam trap testing the valve with a specific functional testing products, sensitivity and reliability of its function is very important to test technology performance valve, valve service life testing is important, its movement and strength and sealing the pressure sensitivity is most concerned about the reliability of the valve test content; this Yongjia County Premium machine itself has developed a number of valve test equipment and maintenance of machinery, professional valve manufacturing and maintenance of equipment to reach the valve product quality and reliability of body strength and sealing tightly.
