BALL VALVE TEST MACHINE

EQUIPMENT INFORMATION :

• Single Screw Design with a movable seal head for height adjustment to suit the face length of valves.
•  Vertical valve test orientation with stem Horizontal
• Hydraulic Clamp system with proportional clamping force adjustment as per the valve size and test pressure for face sealed valve types
• Non compressive for bore sealed valves
• Suitable for Gate , Globe, Ball and Butterfly Valves but without Actuator Assembly in case with control valves
• Test Media : High pressure water and Low Pressure Nitrogen Gas /Air
• Operator’s friendly machine
• Low Maintenance, Low floor space and robust machine
• Different Models to cover up the different range of valves to be tested.
• Provision of safety Guard for enhanced safety during test operations.
• For workshop/plant use.
• Easy, safe and accurate machine for testing the different types of valves
• Bubble jar for air seat leak tightness test
• Pressure Release Valves to release residual test pressure.
• Loading of valves from front.
• PLC for controlling the sequence of operations.

PROPORTIONAL CLAMPING:

• Hydraulic Proportional Clamping System to avoid excessive clamping force.
• Display of clamping force
•  Safety Interlock to ensure that valve remains in clamped mode while under test pressure.

HYDRO SHELL TEST :

• Prefilling at Low Pressure water with air release
• High Pressure built up in valve as per the set value.
• Clamping force rise in proportion to the water pressure rise.
• Holding time, set pressure value as per the selection from HMI/ SCADA screen
• Release of pressure after test

HYDRO SEAT TEST :

•  Prefilling at Low Pressure water with air release
• High Pressure built up in valve as per the set value.
•  Clamping force rise in proportion to the water pressure rise.
•  Holding time, set pressure value as per the selection from HMI/ SCADA screen
• Release of pressure after test
• Seat leak from both side of seat can be tested in the same valve test position ( optional feature )
•  Manual collection of leak water for measurement

AIR SEAT TEST :

• Low Pressure Air as per the set value
•  Holding time, set pressure value as per the selection from HMI/ SCADA screen
• Release of pressure after test
• Bubble Jar for witnessing seat leakage
• Seat leak from both side of seat can be tested in the same valve test position ( optional feature )

BORE SEALING :

• To be used for Butt weld end valves / Ball valves with machined bore.
• Special adapters are needed for bore sealed valves ( optional )
• No compressive force is transferred to valve body

DATA ACQUISITION SYSTEM :

• The automatic Data Acquisition System will be equipped with DAQ hardware to log data for set pressure value automatically and high precision pressure sensors and Digital Display.
• Alternatively, To generate and save customized reports in the computer, a PC based software and other required accessories will be included.
• This will help maintaining all the records inside the pc. USB / LAN can be used for communicating with test terminal for transferring the test reports to customer via internet.
• Automatic digital bubble counter also can be offered optionally for the leak tightness reports.

OPTIONAL :

• SCADA based DAQ system for report generation and report saving in a pc.
• Digital Bubble Counter for seat leak measurement
• Actuator operation system
