ISO 5211 ACTUATOR ASSEMBLY
CNZPV®PFA Lined Weir Type Diaphragm Valve having rugged design to incorporating the best material available is proved by easy, smooth and maintenance free operation for a long time. Extra heavy-duty casting affords high resistance to atmospheric corrosion. Diaphragm valve reduces diaphragm travel for extended service and fine control.
A wide choice is available for body materials, the linings, types of operation and the end connections to satisfy of the most industrial applications. High quality standards are strictly maintained each valve being checked for size, design pressure, operation MOC, finish etc.
Normally the ASTM A216 WCB body with full lining PFA fluoroplastics. Minimum thickness of PFA lining around of 3mm. For some chemicals not so aggressive, the FEP grade fluoroplastic material also is available for economic choice. Due to the diaphragm depart up and down the bodies, this design will let the body and stem not contact aggressive medium to avoid corrosive problem
Product Features:
1) Packing-less / Glandless Design Eliminates emission control problems
2) Isolating PFA/FEP/PTFE diaphragm prevents corrosive or abrasive attack on the operatingmechanism by media.
3) Low Flow Resistance
4) Acid and Alkali resistant
5) Variable flow direction and installation position
6) Thick-Walled Fluoroplastic Lined of the valve body provides high permeation resistance, Vacuum-proof anchored and is almost translucent, thus optimum quality of lining is assured.
