CONTROL VALVE HCVK6
80 - 250
Regulatory valve of HCVK6 type has to work with low and medium erosive media only. It is suitable to control the highly demanding parameters. It also meets demands of the time limited work at critical conditions. HCVK6 valve also applies to flow adjustment of any liquid, as well as a steam when rather small or moderate pressure drops appear. Continuous heavy cavitation, flashing, or throttled flow call for external protection, such as an orifice or diffusor.
HCVK6 valve has an angular casted body topped by the bonnet. The slip-in seat is fixed by construction cage. Main plug is driven by its own bushing. Both bonnet and seat are sealed with graphite spiral wound gaskets (placed in channels). Thus, disassembly and assembly of the valve are easy and do not require any special tools. The single--stage expansion of the medium is controlled by linear shift of the plug. There are two types of plug available: profiled or perforated. The former is advised when media flow goes under the plug.
