As suggested by its name, the sanitary valve is a kind of valve designed to meet specific safety and health standards for medical, beverage, food, and other applications. The sanitary valve's antiseptic performance is essential to maintain the cleanliness of the consumable goods that pass through them.
The body of
sanitary valves is generally constructed with stainless steel, which meets high
health standards. All parts of the body of sanitary valves that interact with
the gas, slurry, or liquid medium are mirror polished. The level of cleanliness
and polishing should meet the standards of health stated by its industrial
function.
Uses of sanitary valves
Sanitary
valves are used mainly in the hygienic areas of hospitals, pharmaceutical
factories, and food processing. They are also employed in regions with no
tolerance of chemical and physical hazards.
How many kinds of sanitary valves exist?
Sanitary
valves can be designed with many variations, but they are categorized into
three types based on their mechanical motions. The three different classes are
quarter-turn, rotary motion, and linear motion.
Linear motion valves
These
sanitary valves use a closing member and move straightly for throttling,
stopping, or allowing the medium to flow. Examples of standard linear motion
sanitary valves are lift check, pinch, diaphragm, globe and gate valves.
Rotary motion valves
These
sanitary valves utilize a valve-closure member, which moves across a
cylindrical or angled path. Common
rotary motion valves are eccentric, plug, swing check, and butterfly valves.
Quarter turn valves
These are
rotary motion valves that only roughly need a quarter-turn (or zero through 90
degrees) stem motion for going from totally closed to open position or vice
versa.
Of these
three different types of valves, not every valve is considered sanitary.
Remember, sanitary valves should meet special sterile needs, especially for
sealing components and valve bodies. The valve seat's sealing surface must not
be toxic. For instance, the material employed for soft sealing and hard sealing
can be rubber and stainless steel, respectively.
If we
shorten the list of sanitary valves, the most common kinds of sanitary valves
are sanitary ball valves and sanitary butterfly valves. The other sanitary
valves are sanitary solenoid valves, diaphragm valves, and sanitary check
valves.
The purpose of sanitary valves
Sanitary
valves are utilized to control and connect conveyance pipes processing
semi-fluid and fluid material in the beverage and food industry. This is
because they are made up of stainless steel, they can guarantee the materials'
hygienic quality during conveyance.
People can
also clean sanitary valves easily. In addition to that, they can disinfect
sanitary valves to keep the pipes hygienic and clean.
Different
industrial applications require that sanitary valves are constructed with
different materials. Most of the sanitary valves are made up of stainless
steel, specifically 316L and SUS304. The manufacturing of these two materials
meets various bio-pharmaceutical and food industries' unique needs. You can easily get these from any reliable valve manufacturer.
Sanitary
valves must be built by meeting five mechanical sealing needs. Two of those
mechanical sealing needs that must be fulfilled for making sanitary valves are
below
1 Must
offer a smooth flow and transition for the medium with no materials'
accumulation
2 Must have
a structure to prevent the fleeing of material out of the sealing surface.
