How to Choose an Appropriate Cast Iron Slurry blade Valve
Percentage
of Solids, Particle Size, Maximum Pressure, Valve Selection, these four factors
have very important effect on the valve selection. The following questions
should be considered to more accurately select any options or modifications to
a valve so it performs as designed in the conditions present on site.
1. What is the temperature of the
media?
Temperature is especially important
when selecting the correct sleeve or seat material for using in the Cast Iron Slurry blade Valve. Some
elastomers are optimized for use in elevated temperatures while others are best
suited for use at ambient temperatures.
2. Is the media corrosive?
Corrosivity needs to be considered
for not only selecting the correct sleeve or seat material, but also when
selecting a compatible material of construction for the metal body, housing, or
gate of the valve. The corrosive nature of the media should also be of concern
when choosing between discharging and non-discharging Cast Iron Slurry blade Valve.
3. Is there potential for
crystallization or scaling to occur?
Valve style, seat and gate design,
special coatings and actuator control schemes can all be modified to
accommodate the build up of scale or crystalized media within the valve.
Special coatings are available to reduce the adhesion of crystallized material
to the gate of the Cast Iron Slurry
blade Valve.
4. Are hydrocarbons present in the
media?
Hydrocarbons cause certain elastomer
seats and sleeves to swell which could lead to poor valve performance. Seats and
sleeves can be constructed of an elastomer material that is specifically
designed for use in applications where hydrocarbons are present in the media.
5. What are the actuation
requirements for the valve?
Pnuematic cylinders and hydraulic
cylinders need to be properly sized to actuate the valve with the given
pressure. Hydraulic power units can be provided to actuate valves in remote
locations.

you want to choose the correct slurry valve, please read above information in
detail.
Now we have already got another order from them for
this Cast Iron Slurry blade Valve. This time,
they also purchased a set of replaceable parts, including packing, seat and
gate.
