Applications / Purposes:
Leveraging the high strength, high temperature/pressure resistance, and excellent corrosion resistance of cast steel, these globe valves are widely utilized across multiple industrial sectors:
1.Petrochemical Industry: Suitable for pipelines conveying crude oil, refined oil, chemical raw materials, and sour gases. They operate stably under high-temperature conditions exceeding 500°C (such as in refinery fluid catalytic cracking units), blocking the leakage of hazardous media like hydrogen sulfide while meeting control requirements for corrosive, flammable, and explosive fluids.
2.Power Industry: Indispensable in the thermal systems of fossil fuel and nuclear power generation. For instance, in boiler feedwater systems, they ensure a stable water-to-fuel ratio by finely adjusting the valve opening to improve combustion efficiency; in steam systems, they control steam flow direction and rate to guarantee the proper operation of steam turbines and other equipment.
3.Metallurgical Industry: Applied in high-temperature, high-pressure fluid pipelines for blast furnace gas and cooling water. Their non-return/one-way flow characteristic eliminates the explosion risks caused by gas backflow, making them well-suited for the harsh operating conditions of metallurgical processes.
4.Municipal Utilities: Used in district heating networks and gas supply systems to control the flow and distribution of hot water and fuel gas. Their superior sealing performance minimizes energy waste and potential leakage hazards. In water supply and drainage engineering, they regulate clean water supply and wastewater discharge, facilitating equipment maintenance and overhaul.
5.Special Operating Conditions: With customized configurations, these valves are applicable to extreme environments, such as nuclear power plant cooling water systems (preventing radioactive substance leakage), LNG storage tank emergency shutdown systems (paired with pneumatic actuators for a response time of <0.5 seconds), and deep-sea oil and gas extraction.
