KOSO Parcol S.r.l. a Socio Unico products

PARCOL 1-4442 series Spraysat multiple nozzle desuperheaters (variable area) are designed to provide optimum performances and high rangeability. The independent spray nozzles progressively activated by the throttling piston, provide a good water atomization down to minimum flow conditions.To improve the quality of atomization and accuracy of temperature control, several sizes of spray nozzles are available. The built-in control system is very compact, reliable and easy to operate. The split body design allows to change easily the orientation of water connection versus the steam piping and greatly facilitate the seat replacement. Angle with downstream water injection DN 1″ x 3″ up to 3″ x 6″
upto ANSI 1500# and job rating CS, Cr-Mo.

VeGA Cryo 1-6940 control valves are designed for very low temperatures (up to -196°C) encountered in the cryogenic industry and in natural gas liquefying plants (NGL). Made with materials selected specifically for this type of service, Vega Cryo valves are normally tested immersed in liquid nitrogen, using helium as the test fluid in accordance with standard BS6364. They are available with either a metal or teflon seal between the seat and the plug (seat leakage class VI under IEC 60534-4) and with low emissions (live-loading) packing certified by TA-Luft.

Three way control valves, Parcol 1-6113 series and 1-8113 series are three-way control valves. 1-6113 series control valves are used for mixing service, whereas 1-8113 series for diverting service.Body materials : carbon steel, CrMo and stainless steel (316, 316L) .Sizes available from 1″ upto 12″

The 1-2480 series PARCOL flanged control valves have a double eccentric disc which reduces torque requirements and seal ring wear by minimizing its contact with the disc. Additional torque reduction is obtained by the profiled drilled integral wings of the design 1-2483.
The drilled wings of 1-2483 make the valve suitable for flow control in cavitating services on liquids and for low noise flow control on compressible fluids.

PARCOL 1-7000 series control valves are especially designed for high pressure applications on high differential pressure water or steam condensate service. They are intended primarily for power plant installations where can be used for the most critical services such as high pressure steam line drain, continuous blow down, lines warm-up, cooling water stop or control for desuperheating systems. Linear or angle type drop-forged steel body with peculiar design of bonnet assure an heavy, compact and reliable construction. The particular design of trim with intermediate, cage guided, double plug, allows to separate sealing surfaces from the modulating ones, warranting, combined with an appropriate material selection, a perfect and reliable sealing.

PARCOL has started the production of specialty control valves for urea plants in 1965; at present, approximately 200 production units where Parcol valves are installed run with full satisfaction.1-4800 angle, split body control valves are designed and manufactured so as to grant good service and longer trouble free life with very reduced maintenance.The original and simple design of PARCOL valves as well as the right selection of the part materials result in great success of the same.

Specifically studied for severe service applications, LIMIPHON valves were designed and built by Parcol in 1971. Based on the concept of multi-path and multi-stage labyrinths (velocity controlled trim), LIMIPHON trim divides flow into many streams to minimize the energy levels and it is the ideal solution for all those applications where high pressure drops are the main cause of noise, cavitation, vibrations and erosions. Low noise, anticavitation 1″ upto 36″ upto ANSI 4500# CS, Cr-Mo, SS.

Parcol 1-5700 Pressure Reducing and Desuperheating stations (PRDS) represent the most universal and compact solution for pressure reduction and desuperheating service of steam turbine by-pass lines, discharging both to intermediate or low pressure sections of power stations. The spherical body shape design, together with the high quality of construction materials, allow a more uniform wall thickness than the conventional ones, fabricated by welding bodies, reducing P/T fatigue effects and improving welded joints quality. Angle with downstream water injection
port size 4″ up to 17″ up to ANSI 4500# and job rating CS, Cr-Mo.

1-2471 series eccentric disc valves give good flow control and excellent seat tightness with high Dp in both directions. End connections are flangeless, wafer type.

VeGA is the most Versatile control valve for General Applications ever designed by Parcol. VeGA is a straight body single seat control valve with cage guided balanced plug designed to withstand the most severe process conditions. The special plug design allows improving valve rangeability by reducing minimum controllable flow and plug erosion. The high pressure recovery factor value compared with conventional contoured plug control valves ensure higher flow rates on compressible fluid service and reduces cavitation risk and effects on liquid service. All versions have quick change trim. Together with the standard high capacity trim, low noise trims and double cage trims are available respectively for critical service on compressible fluids (gas and vapor) and for high differential pressures or for cavitating service where higher pressure recovery factor values are required.
