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.
