Valve Repair

Industrial Valve Repair ensures that the valves are optimized for their specific applications and are functioning at top capacity

Valve Seat Lapping
at Site/at Shop

Industrial Valve Lapping is used when the sealing surfaces of a valve are machined to a smooth finish with the use of a fine abrasive. Lapping is the finishing of a surface that has previously been subjected to grinding.

Control Valve
Test & Calibration

Calibration is the quantitative determination of errors of a measuring device and, where necessary, adjusting these errors to a minimum. The error is comparison with higher standard having traceability to National or International standard.

PSV, PRV
(Safety Valve, Relief Valve) Calibration, Test

INTEGRITY OF SAFETY VALVE

PSV Testing should be considered as a part of the routine maintenance process to adhere to quality controls and safety compliances. As it offers varied benefits, it also ensures the optimum performance of safety controls to eliminate potential risks of hazards such as an explosion or pipeline failure.

Safety Valve Trevi Test at Site

Trevi testing is a method used to test safety relief valves while they are in service, without the need for dismantlement. This testing is done to verify the proper functioning of the valve in real-time, without building up pressure in the entire system

SRV Maintenance
Surge Relief Valve

Surge relief valves can be used in all systems requiring some kind of pressure relief to avoid asset loss due to failure from an overpressure situation.

The main function of a surge relief valve is to quickly open during a pressure surge incident and relieve the high-pressure fluid to any safe outlet.

In the normal scenario, the valve remains in a closed position by the compression of a spring. When the pipeline pressure becomes more than the surge relief valve set pressure, the valve disc quickly opens to release the overpressure.

Again, when the system pressure subsides and reduces below set pressure, the valve automatically closes.

ARC (Auto Recirculating) Valve

Automatic recirculation valves are installed on the outlet of a centrifugal pump discharge line. Their purpose is to prevent the pump from overheating by ensuring that there is a minimum flow through the pump at all times.
