1257/1267/1357/1367 SERIES Zero Bacteria Food Grade Ball & Butterfly Valve With Pneumatic & Electric Actuator

1257-1267-1357-1367 Zero Bacteria Food Grade Valves

Imported Diaphragm valves are with one piece rugged body having cross ribs at flanged ends. They are available in size range of 15mm to 100mm. Its latest inverted design diaphragm remains unstressed while valve is in close position so it gives more service life. The Diaphragm of these valves are available with Neoprene, EPDM, Hyplon, Butyl, PTFE-Coated and pure PTFE. The construction of valve with pure Teflon diaphragm, MS backing ring on bonnet and body which provide extra support and strength. Diaphragms valves are with deep seat allow maximum flow and excellent flow characteristics. Plastic Diaphragm Valves are dependent on the design, especially suitable for highly – pure to heavily contaminated, liquid and gaseous inert and corrosive media. Just as classical control valves also have good control properties, especially for media which is soiled or provided with particles. The major areas of use are the semiconductor industry and microelectronic and a wide variety of industrial applications e.g. water treatment. The valve can be manually, pneumatically and as well as electrically operated.

Zero bacteria means a product which has to be free from impurities and their Key component areas along with important points which is to be covered in Ball valve and Butterfly valve are as follows:
