J*1Y - P*4W/**0 v high
temperature and high pressure power station valve product use Class
of high temperature and high pressure power shut-off valve is
suitable for the ANSI Class***0 ~ ***0 lb, working temperature - *9
~ **0 ℃in the petroleum, chemical, thermal power
plant under various working conditions such as piping, cut off or
connect medium. Applicable medium: water, steam, etc. Operation
mode: manual, gear drive, electric, etc. Product structure
characteristics 1. The product design and manufacturing by
ANSIB*6.*4, standard E**1, can be used with imported equipment
equipped with. 2. The valve lumen self-tightening seal structure is
adopted, and the inner cavity pressure, the higher the sealing
performance, the better. 4 branch pipe at both ends of the disc and
seat sealing surface using department too vertical (stellite)
cobalt-based hard alloy surfacing and become, seal face 6. The
cover depth of the stuffing box is reasonable, packing and
corrosion inhibitor, reliable sealing, smooth switch. 7. The valve
on the sealing structure, which can guarantee the valve opens the
runtime without the valve stem leakage. 8. Electric cut-off valve
opening and closing control by electric actuator, electric
actuator, respectively, with special motor, reducer, torque
control, site operation mechanism, hand, electric switching
mechanism. In addition to on-site operation, remote operation can
be performed. Structure features: 1,
adopting the flange clip pin type, internal thread and key links,
the flange bolt joint structure, etc. 2,
the valve body, valve cover mechanical processing was done on the
automatic line, with light weight, high processing precision,
etc. 3,
the seat and clapper sealing surfaces are coloured cobalt-based
hard alloy plasma spray welding and become, wear-resisting, good
abrasion resistance. 4,
the valve stem corrosion on the surface nitriding
processing. 5,
can be installed in any position on pipeline. DN*0 medium or less
to from the bottom to upper (positive flow "low into the
above") The flow direction of medium or greater DN**0
from dirty or reflux high in low.
