FTA series features:

Eicmation FTA series unbalanced multistage step-down check valve adopts the design of multihole composite cage sleeve combined with unbalanced internal parts.According to the requirements of process parameters,design a number of different buck cage within the set of a combination of a multistage decompression,make the fluid from the first buck cage contact,energy consumption,over multiple step-down cage set gradually reduce the fluid pressure to prevent flash,and the occurrence of cavitation and erosion,improve the service life of the trims.

The use of unbalanced single-seat type,the valve core and valve seat joint surface closely match to ensure very low leakage.

This kind of inner structure is suitable for all kinds of process fluid which can easily produce blocking flow and cause cavitation corrosion.
