CONTROL VALVE HCVB6
15 - 150
Regulatory valve of HCVB6 type is ready to perform with heavy erosive media. It is suitable to control the highly demanding parameters, also during infinite critical conditions. Advantage of this valve is high coefficient of the pressure recycling. It is very useful if there is a risk of high decompression. Thus, can work as injection valve, steam pressure reduction valve, and in bypass pumping.
HCVB6 is straightway valve. Basically, it consists of body topped by the bonnet and of three-step seat-and-plug unit. The seat (inserted to the body and tighten by bonnet) can be all-in-one or divided. Both the bonnet and the 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. Three-step reduction of pressure is of recycling type. Profiled parts of the plug perform first two steps, and piston-type part does the third one. HCVB6 valve works with media flow directed under the plug.
