Control Valve Study Bench Manufacturer,Supplier and Exporter in India
Product Code : ILS-EELE-10420
Indian Lab Suppliers supplies the Control Valve Study Bench (Product ID: 10420) as part of its electronics engineering lab equipment range. It is a water-flow bench for studying how a pneumatic control valve, its positioner and an I/P converter respond to a 4-20 mA signal.
Quick Answer
Water from the supply network passes a 0-3 bar regulator with gauge, a stainless steel needle flow-adjusting valve and a stainless steel pneumatic needle control valve with variable Cv; flow is read on a 60-600 l/h rotameter. A differential pressure transmitter with local display and bleed manifold measures the pressure drop across the control valve. A 4-20 mA current generator with potentiometer and indicator drives the valve servomotor either through an I/P converter (0.2 to 1 bar) or through an electro-positioner, so the effect of the positioner on the valve response can be compared. The air supply has a regulator with air-oil separator and gauge. Please confirm the mains and compressed-air requirements at quotation.

Frequently Asked Questions
What does the I/P converter do?
It turns the 4-20 mA signal into a 0.2-1 bar air signal for the valve.
What is compared on the bench?
Valve response through the I/P converter versus the electro-positioner.
How is flow measured?
With a 60-600 l/h rotameter.
