ARI CHECKO-V 88.003-81 Medium Pressure Class Check Valve PN63-100-160 DN50
Prevents reverse flow reliably in high-pressure steam lines up to 550°C.
ARI CHECKO-V 88.003-81 Check Valve is engineered specifically to prevent reverse flow under high temperature and pressure. In addition, its body and cover, manufactured from 1.7335 high-temperature steel, withstand demanding industrial conditions. Moreover, the DN50 nominal diameter provides a compact structure, and the flanged connection simplifies installation.
The working principle is simple: fluid passes in only one direction, and in case of reverse flow, the disc closes automatically via the spring and seat ring. Stellit 21 seat ring and Stellit 6 coated disc deliver long-lasting sealing performance. Internal parts are stainless steel, and the spring is made of 1.4310 stainless steel. Maximum working temperature is 550°C, with pressure classes PN63, PN100 and PN160.
