Fitur Teknis
Kauntungan saka katup gerbang baja palsu
1. Resistance adi cilik.
2. Pasukan njaba sing dibutuhake kanggo mbukak lan nutup cilik.
3. Arah aliran medium ora diwatesi.
4. Nalika mbukak kanthi, lumahing sealing kurang eroded dening medium apa saka tutup mandeg.
5. Wangun awak relatif prasaja, lan proses casting luwih apik.
Kekurangan katup gerbang baja palsu
1. Loro-lorone ukuran njaba lan dhuwur bukaan relatif gedhe.Papan sing luwih gedhe dibutuhake kanggo instalasi.
2. Sajrone proses mbukak lan nutup, ana gesekan relatif antarane lumahing sealing, kang gampang kanggo nimbulaké goresan.
3. Katup gapura baja palsu umume duwe rong permukaan sealing, sing nambah sawetara kesulitan kanggo ngolah, mecah lan pangopènan.
