Water-gas valves End-of-Line

| What?

Microplan's water-gas valve test rigs are suitable for gas-water valves used as components of gas fired water heaters.

| How?

Microplan's water-gas valve test rigs are intended to perform a full functional test of gas-water valves.

| Where?

In the production line before the final assembly.

| Who?

  • Manufacturers of water heaters
  • Manufacturers of gas-water valves

| Why?

  • Fully automatic machine 
  • Reduction of final test time
  • Reduced faults at final tests
  • Takt time balance
  • Quality improvement
  • Full traceability of test data
  • Human operations driven and controlled by the test rig
  • Test data available for statistical elaborations
  • Market credibility

| Tests

  • Automatic positioning of the valve under test
  • Automatic closure of valve inlet, outlet and by-pass
  • Regulation:
    • PID control on imposed flow rate
    • check of the position of the needle of the valve
    • automatic repositioning of the needle if out of range through automatic screwdrivers software driven
  • Nominal water flow measurement with by-pass closed
  • Leakage test with air (low pressure)
  • Leakage test with water (high pressure)
  • Nominal water flow measurement with by-pass open
  • Valve draining (compressed air injection)
  • Statistical graphs of ongoing tests
  • Automatic marking of good and fault valves
  • Automatic displacement of the valves towards the packing belt

Gas Assemblies R&D

|What?  

R&D test benches are suitable for:

  • gas valves
  • gas assemblies

|How?

R&D test benches are designed to give the operator the maximum flexibility to perform all the tests needed to evaluate the performance of boilers' components.

|Where?

In R&D laboratories.

|Who?

  • Manufacturers of gas boilers. 
  • Manufacturers of gas valves and gas assemblies.

|Why?

  • Product certification costs reduction 
  • Benchmarking 
  • Time to market reduction
  • Preparation for product certification
  • Quality improvement
  • Research and development of new products
  • Full automatic control of flow and temperature regulations
  • Full traceability of test data
  • Test data and report available for statistical elaborations
  • Market credibility

|Tests

  • Full flexible tests. The synoptic panel is available for the operator to:
    • activate any component
    • log any measurement
    • graph any measure 
  • Automatic regulations. The operator can set the parameters to perform:
    • automatic PID regulations of water flow and temperature
    • automatic increasing or decreasing ramps
    • PWM control of fan
  • Test sequence editor:
    • the operator can perfom a series of operations and save them as a test sequence
    • every sequence created can be recalled for future use

Gas Valves and Gas Assemblies End-of-Line

early test of components  

| What?

Microplan's early test rigs GA-EOL are suitable for:

  • gas valves
  • gas assemblies (gas valve + burner + inlet pipe)

|How?

Microplan's early test rigs GA-EOL are designed to perform full functional tests and gas valve pre-adjustment.

|Where?

In the production line before the final assembly.

|Who?

  • Manufactures of gas fired boilers (only conventional)
  • Manufacturers of gas valves

|Which?

GA-EOL test rigs are suitable for gas valves of the different manufacturers available on the market. 

|Why?

  • Reduction of final test time
  • Reduced faults at final tests
  • Takt time balance [read more in our blog]
  • Quality improvement
  • Full traceability of test data
  • Human operations driven and controlled by the test rig
  • Test data available for statistical elaborations
  • Market credibility

|Tests

  • Operator identification through scanner or badge
  • Assembly identification through barcode reading and test sequence automatic loading and running
  • Automatic pre-adjustment of gas valve (min and max) through automatic screwdrivers
  • Gas pressure measurement
  • Gas flow measurement
  • Complete test of gas assembly: multistage leakage test and adjustment
  • Inlet pressure automatic control
