Features:
Excellent Sealing Property
It uses a high-quality rubber material,exhibiting lower compressive strain, for its diaphragm and cushion,resulting in optimum sealing performance.
Tight Seal at Low Torque
Using dynamic analysis by CAE, it is designed so that pressure is distributed evenly.This design allows the hand wheel torque be reduced and maintain shutt off at low torque.
Easier Maintenance
A bayonet mechanism, provided between the diaphragm and compressor, allows the diaphragm to be replaced easily.
Built-in Travel Stop
It contains a revolutionary travel stop mechanism protecting the diaphragm.
Visual Indicator
A color indicator clearly shows whether the valve is fully open, half-open, or fully closed. Because the indicator enters the handle,going out of view when the valve fully closes, the operator can know at the valve position.

PVDF has excellent chemical stablity,excellent chemical resistance and good thermal resisting stability,it can be long operated within the temperature range from -62C to 150C,furthermore,its one of perfect insulation materials with a ligh dieletric constant,which can resist all mediums like salt,acid,alkaline,arene,halogen and so on except for hydrochloric acid and strong solvent.It also enjoy the merits like noflame,breaking resistance,wear resistance and good self-lubricating property.Though its raw materials are imported with high price and ontime investment,its price is greatly lower than imported pipe materials,it will bring you with obvious compressive economic effects on the basis of excellent corrosive resistance,incomparable service lift,high safety coefficient and little maintenance.
