1.3.2 Vary-P valve

For process conditions where up- and downstream pressure varies

much, a special type of valve, VARY-P has been designed. This valve

consists of two valves, a solenoid operated control valve and a fixed

adjusted pressure compensation valve.

1.3.3 Pilot operated valve

For high flow rates the pilot operated valve has been designed. A

solenoid driven control valve controls the pressure difference

across a piston, which lifts the main plunger.

1.3.4 Bellow valve

This valve type is a direct driven, low power, solenoid operated control valve. A special design, incorporating

a metal bellow allows for a relatively large orifice opening to be controlled. The design is suited for low

pressure or vacuum applications.

1.4 Software for physical properties of gases and liquids.

Bronkhorst Cori-Tech B.V. gathered the physical properties of over 600 fluids in a database called FLUIDAT.

Application software, such as FLOW CALCULATIONS, enables the user to calculate properties, not only at

20°C / 1 atm but also at any temperature/pressure combination, both for gases and for liquids.

Apply to your distributor for more details of this software.
