Notice: DirectionA and fl owbelow the seat 1,Valves with DirectionA and fl ow directionbelow the seat ensure long service life. 2,Valves used for liquid media are waterhammer-free. 3,Valves with orifi ce DN15/DN20/DN25 are ideal for the operationg pressure of 0.3Mpa. vavles with orifice DN32/DN40 are operated with double-acting actuators DN100. Valves with orifi ce DN50 are operated with double-acting actuators DN125. DirectionB and fl ow above the seat Valves with DirectionB provide high sealing integrity, used for steam and gases media. there is a danger of waterhammer ,When the valves used for liquid media.
