Steam stop valve is a valve specially designed for controlling and cutting off the steam flow in steam systems. This type of valve is widely used in steam pipeline systems in power plants, chemical industry, petroleum, pharmaceutical industry, textile, food processing, heating and other industrial fields to cut off or connect the steam flow.

Globe Valves
Main features of steam globe valves include:
1. Structural design: usually adopts straight-through or angle structure, with a valve disc (also known as valve core) inside the valve, the movement trajectory of the valve disc is axial, and it is connected to the handwheel or actuator through the valve stem. The sealing surface of the valve disc is designed to be a plane or cone that matches the valve seat to ensure a good sealing effect.
2. Sealing performance: The sealing performance of the steam globe valve is crucial, because steam leakage under high temperature and high pressure may cause energy waste, environmental pollution and safety hazards. High-quality steam globe valves usually use hardened sealing surface materials (such as cladding carbide or nickel-based alloy) to enhance wear resistance and high temperature resistance, and some are also equipped with bellows sealing design to achieve zero leakage of the valve stem.
3. Material selection: In view of the high temperature and high pressure characteristics of steam, the main material of the steam globe valve is generally selected from high temperature resistant, corrosion resistant, high strength cast steel, stainless steel and other materials to ensure that it will not fail under long-term high temperature and high pressure working conditions.
4. Operation mode: According to the needs, the steam globe valve can be operated manually (through handwheel, lever, etc.) or by automatic control methods such as electric and pneumatic.
