◆The L20900 a perforated cage sets of combination with unbalanced trim design, in accordance with the requirements of the media process parameters, design multiple different buck buck trim a multi-level the cage sets of combination, fluid from contactonly first buck cage sets began to consume energy, gradually reduce the fluid pressure to prevent flashing through multiple antihypertensive cage sets, the occurrence of cavitation cavitation growth trim life. Unbalanced single-seat, heart valve and valve seat joints work closely together to ensure a very low leakage. The structure of such inner parts suitable for a variety of easy to produce blocking flow caused by cavitation process fluid conditions. Imbalance pieces to fit the specifications of the smaller diameter valves. (Large diameter specifications see L40900)
