First, the features and performance: 1, the amount of condensate occur apply strong, then intermittent emissions, but also continuous emissions. 2, the internal parts made of stainless steel and is mounted on the valve cover, maintenance is very convenient. 3, unmatched SCCV shut down the system, a unique design, with error compensation lever mechanically generated, to avoid collision rigidity when closed, closed very reliable, long life. 4, high back pressure 90% 5, reliable :( vapor separator through the U-shaped channel into the lower part of the valve), always in the closed valve state, effectively preventing the leakage of steam. 6, lip shield floating in the anti-water hammer, bucket superiors did not overflow vent, which can effectively prevent steam locking an air blocking phenomenon. (Non-condensing of hot air can be excluded) Second, use: for steam main, public cylinders, heat transformer, curing machines, hot-air dryer, drum dryers, distillation, concentration device, hospital sterilizer and so on. Smoke small, lightweight ES5 type best suited for air conditioners, washing machines, dyeing and sound machines. The ESU5 type stainless steel designed for the food industry, hospitals steam equipment manufacturing. Third, wear-resistant SCCV off mode: SCCV shut down the system is self-centering, self-closing system (Selt Closing and Cante-ring Valve Sysstem) abbreviation, the same below. The closed approach breaks through the traditional design, clever use of condensation inside the suction and pressure valves soil and water flows out of the valve body is closed. The spool has a balancing role in the closing process, reducing the wear and tear inside the valve seat.
