德国莱克品牌,进口气动蒸汽调节阀，采用套筒导向，压力平衡式阀芯，适用于压差较大的场合。利用平衡密封环代替上阀座，使传统的套筒双座阀结构变为套筒单座结构，这一改进大大提高了套筒阀的泄漏等级。阀芯利用压力平衡式结构，启闭力小。通过较小的执行机构推力就能控制高压差的工况。广泛应用于要求动态稳定性好的中低温、中低压管线的流体控制。密封性能好、允许压差大。套筒导向，导向面积大，稳定性好，结构紧凑，可以快速在线更换阀内件，维修效率高，节约人力和时间。平衡式阀芯结构确保所
需的执行机构推力***小。
The 10P00 Series cage single-seat control valve adopts the top guided unbalanced structure, featured by high strength, he***y load, S type flow channel, low pressure drop loss, high flow coefficient, wide adjustable range, high flow characteristic precision, etc. Featured by tight shut-off, this kind of control valve is suitable for applicati*** with relatively low differential pressure. It is suitable for controlling medium flow or pressure.
The cage adopts the press-in type seat design, which solves the problems of difficult disassembly and high leakage of the traditional thread screw-in type seat and prolongs the service life. The flow to open design is adopted, and the medium flow direction tends to the opening direction of the valve with good controllability of ***all opening and low flow characteristic distortion. Special cages with noise reduction and anti-c***itation functi*** can be offered according to the requirements in different service conditi***.
