4 In Black Color Nitrile Butadiene Rubber Pulse Jet Valve Diaphragm Working more than 1 Million Cycles
The Pulse Jet Valve Diaphragm made of NBR.It is a kind of synthetic rubber, copolymer formed by polymerization of acrylonitrile and butadiene monomer, and has the advantages of good oil resistance (especially alkane oil), high abrasion resistance, good air tightness, good heat resistance, strong adhesion, good aging resistance and so on.
Although the chemical and physical properties of NBR vary with the amount of cyano in the polymer, NBR remains resistant to the dissolution and corrosion of grease, gasoline and other solvents. The higher the content of cyano group in the polymer, the stronger its corrosion resistance and the worse its elasticity.

Further Descripation of the Diaphragm
1, Diaphragm (rubber or fabric reinforcement in rubber diaphragms)
is a precision functional part used for checking pressure or
changing fluid pressure into driving power
2, Diaphragm has been widely used in automobiles, controllers,
household gas facilities and appliances with form of pressure
sensors, actuators, On-Off switchs
3, Fabric-reinforcements in rubber diaphragms utilize a layer of an
engineered fabric material as parts of the diaphragm construction.
This layer of fabric give tremendous design felxibity
4, A very thin-walled diaphragm can withstand high pressures while
remaining very flexible and responsive to minior pressure
variations
5, Fabrics made of polyester, nylon and silk ard commonly used for
most applications, fabric used for those applications exposed to
high temperature. For those applications that require extremely
high strength
6, All types of elastomers, such as nitrile, EPDM, fluorocarbon,
neoprene, silicone, fluorosilicone, can be used in the
fabric-reinforced diaphragms.
7, Fabric-reinforced diaphragms offer advantanges of no leakage, no
lubrication, no breakaway force, no friction, high strength,
functionality over wide pressure ranges, low cost, simple design,
versatility
Maintenance
Before conducting any maintenance activity on the system ensure
that components are fully isolated from pressure and power
supplies. Pressure and power should not
be reapplied until the valve has been fully assembled.
Diaphragm and pilot unit inspection should be conducted annually.
If you have the special request for Diaphragm color or specifaication,also can be customized
