First, detailed materials of the product [the electron type
electronic regulating valve of three direct links ]:
Type of the products: ZDSF (H ) type
Name of product: Electron type electronic regulating valve of three
direct links
Characteristic of the products: ZDSF (H) type frank journey shunt ,
meet electronic regulating valve , shunt by three direct links ,
meet valve is it import with Germany PS serial frank journey
electronic executive body make up to mix. There are servo systems
in the electronic executive body , does not need to mix the servo
amplifier separately , is it import to control signal (4- 20mADC or
1- 5VDC ) and single-phase power can is it turn round to control ,
realize to pressure , flow , temperature , liquid location ,etc.
regulation of parameter to have, adopt balance type valve fill
structure in , have valve fill stability in to be fine difficult to
produce shake , low is it is it pigeonhole difference to be heavy
to use to allowing noise, characteristic such as being simple of
line , the regulating valve is used in flow coefficient big
extensively, in the automatic control system of industry which
requires such trades as tighter electricity , metallurgy ,
petroleum , chemical industry , environmental protection ,etc.
of the letting out amount.
Second, valve body:
FormCast the valve in three direct links two-seater
Nominal and open directly: 25- 300mm
Nominal pressure: PM1.6 4.0 6.4MPa
Connect the formThe flange type presses JB78- 59 JB79- 59

Fifth, executive body:
Type: PS available , 3810 , ZAZ type (within DN100 ) , DKZ type
serial electron type straight journey executive bodies (above DN100
). The explosion-proof type selects 3810 series for use
Technical parameter and performancePlease consult the corresponding
executive body and valve positioner manual.
