CONTROL VALVE HCVK7

HCVK7 valve is an angular one. Basically, it consists of casted body topped by the bonnet, of a plug with a stem driven through guide bushing, and of the slip-in seat with anti-flashing bushing fixed by construction cage. 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. Liquid medium goes over the plug, then evaporates in anti-flashing bushing vents. Thanks to dispersion of kinetic energy of the water-steam mixture the valve’s body does not undergo the substantial erosion. The bushing’s lenticular outlet helps to combat the pipe-line’s erosion behind the valve. There are two types of plug available: profiled or perforated. HCVK7 valve works with media flow directed over the plug.
