Standard: ASME B16.34 or GB12224

Main part material: carbon steel, alloy steel, stainless steel

Specification: nominal diameter: 2"-16"

                         nominal pressure: 900lb-2500lb

Temperature range: carbon steel: ≤425℃ alloy steel: ≤595℃ stainless steel: ≤540℃

Description:

1. It is widely in high temperature, high pressure working system;

2. Inner cavity is adopted with metal sealing ring  or pressure-self-tightening seal form;

3. Inner cavity is sealed with stainless metal sealing ring;

4. To avoid "Boiler effect" in the inner cavity, if customer allows, a bypass-valve can be installed on the valve, protecting seal in the inner cavity and preventing the seal surface from hurt caused by high torque when opening the valve;

5. The valve seat is welded to the body and the sealing surface is over-lay welded with hard alloy or Cr13 alloy;

6. Mode of operation: hand wheel, gear transmission, electric.
