technical parameters
detailed products description
1.ZSHO type pneumatic piston cutting ball valve (hereinafter referred to as cutting ball valve), is the pneumatic unit combination instrument product, generally actuators with electromagnetic valve pneumatic components combination to use.When pneumatic actuators to receive signals from adjusting instruments, driving the stem, ball core for the rotary motion, make valve open (close) by the position turned to close (open) position to achieve to the pipeline within the medium circulation, cut off control.
Features
Body for the whole structure,smoothy.Seat by thread set of closely coated on valve spool,Reduce leakage.Seat by two different material production, can adapt to the needs of different temperature range.
Connection standard
Connection mode: flange (DN25 ~ 150)
Flange standards: cast steel flange GB9113-88 (according to PN16, 40)
The body sealing for PN16 type: the flange for the concave convex, PN40
