The spiral wound gasket has high compression and resilience performance, with multi-channel sealing and certain self-tightening function. It is less sensitive to surface defects on the flange pressing surface and does not adhere to the flange sealing surface, which can partially eliminate the inf...
Check valves allow fluid to flow in only one direction and prevent backflows. They work automatically. The valve opens when fluid flows in one direction, leading to a higher inlet pressure, and it is closed when fluid flows in an opposite direction, resulting in a higher outlet pressure.
Valve leakage occurs may due to the following five reasons: falling off of the disc, packing leakage, sealing surface leakage, leakage between body and bonnet, and leakage of sealing ring connection. For different reasons, respective measures can be taken.

This is because the safety valve is responsible for reducing the pressure in the system as quickly as possible to prevent damage caused by excessive pressure as quickly as possible.
In system station, the return flow of waste water to the pump can cause harmful flap strokes and pressure waves. The Flowork can avoid these harmful pressure waves and flap impacts.
Flowork supplies API600 gate valve with the material as carbon steel ,stainless steel and bronze etc , tailor-made for international large-scale plant engineering for chemical plants, refineries and petrochemical plants, and for power station engineering. In addition to our own Flowork valves, we...
Flowork ensure complete external tightness, thanks to the gland zone, which is permanently separated from the flowing medium. Bellow valve limits or stops any kind of leakage that could lead to a facility damage, as well as cause harm to the environment. These products do not require a constant s...
