Why Choose Us
Disc & Clapper Replacement
Worn, cracked or deformed stainless steel, cast iron and bronze discs are re-machined to original tolerances and replaced; backflow is definitively prevented.
Spring & Hinge Renewal
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.
Seat Surface Lapping
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.
Water Hammer Analysis & Prevention
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.
