Technology Parameter

Installation & Maintenance:

1 Clean the pipes carefully from any residue, dribble or welding residue, to avoid
any damage to the seal.
2 To be installed as required, preferably with actuator in upright position
3 Connect the pipes according to the reference points (fl ow direction)
found on the valve body.Only disassemble the actuator if required by customer.
4 Before taking the valve apart, depressurize the media supply and pilot air supply
piping system.

Notice:

Direction A and fl ow below the seat
1,Valves with Direction A and fl ow direction below 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.
Direction B and fl ow above the seat
Valves with Direction B provide high sealing integrity, used for steam and
gases media.
there is a danger of waterhammer ,When the valves used for liquid media.
