Angle Abrasion-Resistant Shut-Off Plug Valve:
The angle abrasion-resistant shut-off plug valve is installed as the critical shut-off valve on the bottom outlet branch of the hot high-pressure separator, isolating the reactor from downstream piping to allow maintenance of the high differential pressure angle abrasion-resistant control valve assembly.
Product Specifications
Nominal size: 14" nominal
Pressure class: CL2500
Design pressure: 20.55MPa
Design temperature: 482°C
Media: gas-liquid-solid three-phase
Hot High-Pressure Separator Level Control Valve:
The hot high-pressure separator level control valve is located between the hot high-pressure separator and hot middle separator of the direct coal liquefaction unit, operating in a high-temperature, high-pressure, high-sulfur environment with coal-oil slurry media — extremely severe service.
Product Specifications
Nominal size: 12"X14" nominal
Pressure class: CL2500
Design pressure: 18.7MPa/2.9MPa
Design temperature: 482°C
Media: gas-liquid-solid three-phase
High Differential Pressure Control Valve:
The high differential pressure control valve handling corrosive acidic water is located at the bottom of the cold high-pressure separator, controlling the water flow. It offers excellent corrosion and abrasion resistance. The valve is an angle flow-to-close structure with a linear motion stem, actuated by a cylinder.
