Valsteam ADCA Pressure Reducing Valves

Pressure reducers are essential components in most fluid distribution systems. Valsteam Adca offers you a wide range of options, from the simplest direct acting valve, to the most sophisticated pilot valve and in various types of construction. We have, in storage, the necessary materials to quickly manufacture a soft valve or higher hardness, by additioning cobalt alloys and others.

Our flexibility also allows us to manufacture some products by measure. The choice is broad and, in some cases, we can have several solutions for the same situation, so we will always be available to study and suggest the best.

Main Features

  • Compact design
  • Completely machined from barstock material

Required info for selection

  • Type of medium
  • Upstream and downstream pressures
  • Operation temperature
  • Flow rate (maximum and minimum, if applicable)
  • Type of pipeline connections

Direct Acting Pressure Reducing Valves

The reduced pressure acts on the underside of the diaphragm, bellow or piston so balancing the load of the pressure adjustment spring and moving the inner valve through a spindle to obtain the desired controlled pressure.

Pilot Operated Pressure Reducing Valves

pilot-operated pressure reducing valvesThe reduced pressure medium through a controlled
pressure pipe, acts on the underside of the diaphragm of
a pilot which, in turn supplies steam (or gas) at variable
pressure into the upper chamber of the piston operator,
which regulates the main inner valve.

In both options, pressure setting is adjusted by varying
the pressure exerted by the control spring by turning the
adjustment hand wheel.

Pressure Reducing Station

Valve selection diameter must be done according to the actual flow of steam, liquid or gas passing through the valve, the minimum intel pressure and the desired reduced pressure.
