Hastelloy stop valves have excellent corrosion resistance and alkali cracking resistance in caustic solutions at all concentrations and temperatures. Hastelloy stop valves produced by Shanghai efekai valve are mainly used in high temperature concentrated alkali corrosive medium conditions. It has the following characteristics:

1. Hastelloy stop valve has compact structure, reasonable design, good valve rigidity, smooth channel and small flow negative coefficient.

2. Flexible graphite and tetrafluoro packing are used, which has reliable sealing and light and flexible operation.

3. The drive mode of Hastelloy stop valve is divided into pneumatic, electric and gear pneumatic transmission.
