When it comes to chemical valves, the selection of bushings is
crucial for ensuring smooth operation, durability, and resistance
to corrosion. Two popular options for chemical valve bushings are
316 stainless steel and steel-backed bronze bushings.
316 Stainless Steel Bushings:
316 stainless steel bushings are an excellent choice for chemical
valves due to their exceptional corrosion resistance. This alloy
contains molybdenum, which gives it superior resistance to acids,
chlorides, and other harsh chemicals compared to other stainless
steel grades. As a result, 316 stainless steel bushings can
withstand harsh environments and chemicals commonly used in
chemical processing.
In addition to corrosion resistance, 316 stainless steel bushings
also offer good strength and wear resistance. They can maintain
their dimensional stability and mechanical properties even under
extreme operating conditions, ensuring reliable performance for
chemical valves.
Steel-Backed Bronze Bushing:
Steel-backed bronze bushings are another popular choice for
chemical valves. These bushings combine the strength and durability
of steel with the lubricity and corrosion resistance of bronze. The
steel backing provides the necessary structural support, while the
bronze layer offers superior wear resistance and lubricity.
Steel-backed bronze bushings are often used in applications where a
high degree of lubrication is required. The bronze layer can be
impregnated with lubricants or oil, which helps reduce friction and
wear during operation. This makes them an ideal choice for chemical
valves that require smooth and reliable movement.
In summary, both 316 stainless steel and steel-backed bronze
bushings offer excellent performance for chemical valves. The
choice between the two depends on the specific requirements of the
application, including the chemicals used, operating conditions,
and lubrication requirements.

It is backed with stainless steel with porous bronze sintered on it
and polymers imbedded into the bores of the bronze. The stainless
steel back provides the bush with stronger mechanic strength and
load capability. By combining the metals and the polymers tog, the
products are endowed with the lower friction coefficient and good
capacity of anti-abrasion and self-lubrication. Moreover, the
stainless steel back can be effectively preventing chemical
erosion. This series are widely applied in printing and dyeing
machines, and machines used in the ocean industry, etc.

This new material use the PTFE fibre fabric overlay on metal
backings, the fabric have very high load capacity and much longer
operating life compare with conventional 3-layer bushes. The metal
can be carbon steel. stainless steel.
