Overall Dimension
Notice
Flow direction below the seat (direction A)
1,Valves with flow direction below the seat (direction A) ensure
long service life.
2,Valves used for liquid media are waterhammer-free.
3,Valves with orifice DN15/DN20/DN25 are ideal for the operating
pressure of 0.3Mpa.
Vavles with orifice DN32/DN40 are operated with double-acting
actuators DN100.
Valves with orifice DN50 are operated with double-acting actuators
DN125.
Flow direction above the seat (direction B)
Valves with dirction B provide high sealing integrity when used for
steam and gases media.
There is a danger of waterhammer ,when the valves are used for
liquid media.
