Check valve repair, disc/clapper replacement and periodic maintenance for swing, lift and wafer type valves of all brands and models. From pump protection to backflow prevention, from compressed air systems to chemical lines — our certified team is by your side.
Worn, cracked or deformed stainless steel, cast iron and bronze discs are re-machined to original tolerances and replaced; backflow is definitively prevented.
Broken or fatigued springs and worn hinge pins are renewed with stainless materials suited to the pressure class; valve closing speed and water hammer resistance are optimised.
Scratched or rough disc and body seating surfaces are machined on precision lapping benches to restore metal-to-metal sealing; zero back-leakage is guaranteed.
The effects of water hammer caused by pump shutdowns are assessed; closing time is optimised through the right valve type and spring configuration to extend system service life.
Check valves are indispensable safety elements in industrial and infrastructure systems, securing unidirectional flow and protecting pumps and compressors against backflow. With swing, lift, wafer and dual-disc types, they serve a wide range of applications.
Protection against backflow and water hammer in centrifugal and submersible pumps; disc and spring replacement with on-site pressure testing
API 6D compliant check valve overhaul and leak testing for high-pressure crude oil, natural gas and aggressive chemical fluids
On-site overhaul and hydrostatic pressure testing of large-diameter flanged check valves in potable water, irrigation and wastewater treatment systems
Notify us by phone or form. A response team is planned immediately.
Our technician arrives and inspects the disc, spring, hinge and seating surface, then prepares a detailed report.
Work begins immediately upon approval. No surprise costs.
Delivered with a 12-month warranty after hydrostatic pressure and back-leakage testing per API 598 standard.
