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.


High pressure urea service

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.

Materials are adequate for urea and carbamate fluids and comply with the material specifications for this service of main Licensors such as Snamprogetti, Stamicarbon, Urea Casale and others.
Connections are obtained directly on the single piece that constitutes the valve body in order to keep down the weight, whereas the shape of internals does not leave dead zones. In fact dead zones are a cause for corrosion since carbamate strengthens its corrosive action particularly in these zones due to the failure of oxygen protection (passivation).

port size 4″ up to 17″

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.
The pressure reduction is mainly achieved through two stages: the first stage has the function to adjust the flow rate by means of a drilled cage trim, the second stage, designed with fixed throttling section, has the double function to generate a backpressure on the first stage by reducing fluid velocity and generated sound pressure level, and to convey the steam towards the injection chamber, at speed and distribution suitable to optimize the desuperheating process.
The desuperheating section, put immediately downstream the second stage, consists of the injection chamber complete with injection nozzles or a different Parcol desuperheater.


1/2″ up to 1.1/2″Stainless Steel

1-6330 series THECO are suitable for ON-OFF service in low potentiality processes but under continuous and severe conditions where maintenance must be minimized. These valves are used in tyre, food industry, plastic forming etc.

Size: 1/2″ to 1.1/2″, connections: screwed and flanged ends.
Available two and three way style.
