BALL CHECK VALVE WITH THE FLOW PART OF FLUOROPLAST-4 (“КОШФБ”)

Armoured ball check valves are designed for shutting off medium flow inside a pipeline in case of dramatic pressure build-up, high resistance or hydraulic shocks occurrence.
Making the valve flow part of “Ф-4” enables its use in case of handling especially aggressive media at temperatures ranging from - 15 to + 110 °С and pressure up to 1.0 MPa (10 kgf/ cm2). Valve installation at the injected liquid inlet of “НСФ1” and “НСФБ” jet pumps instead of spool is recommended.
The operating position of the valve is vertical, in the open state. “КОШФБ” valve of seven dimension types with the nominal inside diameter of 10, 15, 20, 25, 32, 40 and 50 mm is produced. The connecting dimensions are given in the table.
