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.
