Body Plates Seat body Spring Cast iron GG 5 (EN-GJL- DIN 19) Nodular cast with nickel plating EPDM o NBR Stainless steel Please contact our Technical Department for information about dimensions of a superior size. On request, the UNICHECK manufacturing program includes the supply of other materials for bodies and plates, as well as ICONEL springs so as to offer greater protection against wear and tear. Please contact our Technical Department for more details about supplies. Principal applications The principal applications of the standard supplies of UNICHECK valves are Ventilation, Air Conditioning, and Heating. With nitrile joints, they are used in factories for lubrication, mineral oils, industrial fats and other derivatives.

The Cv is the number of USA gallons per minute which results in a pressure loss of 1 Psi through the valve with 5 0 C. Equivalent Cv=1.17 Kv. Kv indicates the volume flow rate in m/h for water at 5oC under a pressure differential of 1 kg/cm.
