ARI CHECKO-V 88.003-81 Medium Pressure Class Check Valve PN63-100-160 DN20
Reliable reverse flow protection for high-temperature, high-pressure steam systems.
ARI CHECKO-V 88.003-81 Check Valve is engineered to prevent reverse flow in critical facilities such as power plants and refineries. Moreover, its body is made from 1.7335 high-temperature steel, offering resistance up to 550 °C. Therefore, it maintains safe flow control under demanding thermal and pressure conditions.
The valve operates across PN63, PN100 and PN160 pressure classes and provides a compact structure with a DN20 flanged connection. When flow direction reverses, a Stellit 6 coated disc and a Stellit 21 seat ring close automatically. In addition, stainless steel internal parts and spring deliver superior corrosion resistance, protecting system equipment from reverse-flow damage while improving efficiency and reducing maintenance costs.
