Non-freezing check valve KON
Check valve for bypass excessive pressure from the annulus. It is welded into the intersection of the oil and gas lines during tree installation. The valve is flushed with a stream of produced liquid which prevents the valve from freezing at low temperatures. The valve design allows adjustment to the required pressure drop (up to 0.3 MPa) without disassembly in the operating mode.
