• A Wide-ranging Selection of Chemically Inert Polymers

The diaphragm material is chemically inert plastics such as PTFE, PFA and PFA or rubbers such as EPDM, Leather, Silicone or NBR. Such inert materials make the valves suitable in applications requiring the maintenance of media purity and corrosion protection.

PTFE is a fluorocarbon that can be molded into various shape and configurations. It is also chemically inert hence resistant to multiple chemicals in the media being controlled. It can also withstand high heats making the valve suitable for delivering millions of cycles in extreme temperature applications.

PFA is a copolymer with fluorocarbon chain too but resistant to temperatures over a wider range than PTFE. PFA is also available in various grades of cleanliness and purity so you can pick what is suitable for your sanitary needs.

• Field Replaceable Seats

The modern design features replaceable seats so that you can fit the seat you want to achieve desired flow characteristics. Field replaceable seats make it easier to switch between the saddle and straight-through flows.

• Steel or Plastic Body Type

Most valves bodies are engineered from stainless steel alloys such as cast iron, ductile iron. Alloy 20 and more that are chemically inert too and resistant to corrosion. The steel body makes the valves durable and fit for rough operation settings. You can also get plastic body type featuring PTFE, PVC-C, PP. ABS or even more chemically inert polymers.

• Body Lining

Body lining is used to eliminate internal crevices and keep off medium from corroding and interfering with the valve’s internal parts integrity. Based on your operation temperature and chemical settings, you can select from the unlined or lined valve types. Commonly used lining materials include the rubber, fluorine plastic, and glass.

Applications :
The silicone O ring is often used in the working environment that needs to resist of heat, chemical corrosion, oil, etc. The o rings are widely used in metallurgy, chemical, automobile, mechanical and electric power industry.
