First, rubber stopper valve purposes:

The valve is designed to control the general corrosive medium, the body cavity surface covered with a variety of rubber to choose from, suitable for different working temperature and fluid pipe, with high strength, good corrosion resistance.

Second, rubber stopper valve material:

Body	Cast iron, ductile iron, carbon steel, stainless steel
Butterfly plate	Cast iron, ductile iron, carbon steel, stainless steel, carbon steel fully coated rubber or fluoroplastic
Valve stem	Carbon steel nickel-phosphorus, stainless steel
Seat ring	Natural rubber NR, neoprene CR, nitrile rubber NBR, EPDM rubber EPDM, fluorine rubber FKM
Handwheel	Cast iron, carbon steel

Third, the rubber stopper valve test:

Lining: Spark
testing and inspection according to GB / T13927 standard
Nominal pressure: PN (MPa)
Body: PN × 1.5
Seal: PN × 1.1
