Oil-free globe valve
Overview
The opening and closing part of the globe valve is a plug-shaped valve disc. The sealing surface is flat or conical, and the valve disc moves linearly along the center line of the valve seat. The movement form of the valve stem, (common name: concealed stem), also has a lifting and rotating stem type, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
Therefore, this type of globe valve is very suitable for shutting off or regulating and throttling. Since the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable shut-off function, and because the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for regulating flow.
Characteristics of oil-free globe valve
1. Flame-proof and fire-retardant: The main components are made of copper alloy, which is a non-flammable material and will not produce sparks even if it collides with solid particles in high-speed airflow. Therefore, this valve has the best flame-proof and fire-retardant performance
2. Safe and reliable: This valve is equipped with dust-proof, waterproof and oil-proof devices. All valve parts in contact with oxygen have undergone strict degreasing and oil-free measures before assembly. The filler material is polytetrafluoroethylene, which ensures safety during use. reliable.
