control valve test modules :

module-ht1 : vacuum system

• this will be useful for quick pre filling of test valve by way of evacuation the complete valve cavity before pre filling is started
• this will help eliminate compression of residual air inside valve and help increase sealing life and hazardous way of escaping trapped air outside forcibly.
• the system will include a suitable vacuum pump, moisture receiver tank with drain valve, hose pipe, vacuum gauge/ sensor and isolation valve for vacuum line.

module-ht2 : prefill system

• low pressure prefilling pump arrangement for prefilling of valve before test
• water tank with level controller and drain valve.
• water filtration and recirculation system
• safety bypass valve

module-ht3 : high pressure hydro shell test

• hydro shell test with high pressure water to suit the different pressure class of the valve under test
• hydraulic power driven pump which is highly reliable, self lubricated and less maintenance prone has a larger discharge capacity to built up required pressure in a reasonable time compared to air driven hydro-pneumatic pumps.
• dual speed design for better control over pressure.
• hydraulic driven high pressure pump, cartridge filters, suction and discharge nrv and accessories.

module-ht4 : high pressure hydro seat test

• required pressure will be applied from pressure source available .
• pressure drop to be observed.
• seat leak in a flow direction of a valve. Pressurization from both side available as option

module-ht5 : low pressure air seat test system

• dry utility air at 7 bar inlet air pressure shall be provided by customer for this test
• air regulator, pressure transmitter, solenoid valve , nrv etc will be incorporated
• seat leak in a flow direction of a valve. Pressurization from both side available as option

module-ht6 : high pressure air test system ( optional )

• provision of high pressure air compressor suitable for generating test pressure upto 300 bar ( 4500 psi ) and suitable for testing of valves upto 200 bar ( 3000 psi ), with high pressure reservoirs for storage and test pressure control needle valves/ gauges and other required hardware.

module-hc1 : low pressure air seat leak detection and measurement system

• rotameters of various ranges with isolation ball valves for air seat leak measurement ( range will be selected as per the customer’s requirement of test parameters )
• digital mass flow meter available as an option ( range will be selected as per the customer’s requirement of test parameters )
• bubble jar arrangement for visualization of seat leak for very small amount of leakages across seat.
• digital bubble counter available as an option for visualization of seat leak for very small amount of leakages across seat

module-hc2 : seat leak testing arrangement by water

• required pressure will be applied from pressure source available .
• measurement of leakage through seat shall be done manually by collecting the same in a marked beaker from the non pressurized side of seat.

actuator operations :

module-ac1 : pneumatic actuator operating system

• a system for providing air pressure for signal ( 0-20 psi )/ afr for 3-15 psi with panel mounted gauge with gauge saver ( signal pressure )
• a system for providing inlet air to actuator ( 0-100 psi ) / afr 0-85 psi with panel mounted gauge and regulator
• a system for cyclic operation of air actuator / pneumatic cyclic operation with editable holding time ( double solenoid pneu valve )

module-ac2 : electric actuator operating system

• a system for providing 4-20 ma output signal ( feeder for valve calibration )
• 230v ac universal supply
• 24vdc and 110 v ac power supply
• provision to provide 24 v dc / 230 v ac power connection

general information :

test skid :

• horizontal mounting of valves with stem in a vertical orientation- valve mounting position as piped in most situation + ease of loading and unloading of valves.
• most suitable design for valves with as well as without actuator assembly
• suitable for face sealing of flanged end and socket end/ screwed end valves.
• robust, safe and operator friendly machine
• the rated capacity of test skid is the maximum reaction force the skid is designed for. ( please refer model chart for selection )
• the 2 pillar frame is designed for better space for visual inspection and loading.
• the common sealing plates with o-rings for face sealing of certain range of valve sizes and pressure class.

hydraulic clamping

• hydraulic auto force control clamping system to avoid excessive clamping force over valve body.
• provision of inching type button to increase the clamp force
• display of clamp force on hmi/ scada screen.
• safety interlock to keep the valve in clamped position while it is under test pressure
• provision for local soft clamp , clamp force inching and de-clamp push button
• high precision, reliable pressure transmitter for feedback of oil pressure
• various interlocks for enhanced safety of operator and equipment

auxiliary functions :

• hydraulic intensifier system with controls for smooth rise of pressure and avoiding over shooting of pressure beyond predefined overshooting pressure limits.
• valve center height support vertical movement
• valve center height support horizontal movement
• auto isolation of prefill line ( optional )
• auto decompression ( optional )
