YOONAD VALVE FACTORY a leading industrial valve manufacturing enterprise, is renowned for its good product quality and customer service.
We specialize in the research, manufacturing, testing, and sales of valves. Our main product is the ball valve, butterfly valves, gate valves, globe valves, check valves, and have more valves which used in different applications.
If you want know more about other valves,you can contact me.
The structure design of cast steel globe valve absorbs advanced technology at home and abroad, the valve body adopts spherical structure, beautiful modeling, the valve seat valve flap adopts conical sealing structure, reliable sealing. Product use Cast steel globe valve is suitable for Class150 ~ 300, working temperature 29 ~ 425 ºC (carbon steel) or 40 ~ 550 ºC (stainless steel) in a variety of pipeline, used to cut off or connect the pipeline medium, the choice of different materials, respectively, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
1, product design and manufacture according to ANSIB16.34, E101 standard, can be used directly with imported equipment. 2, the valve cavity using self-tight sealing structure, the higher the pressure in the cavity the better the sealing performance, the ends of the branch pipe for the pair of welding, to adapt to different takeover requirements.Globe valve stem generally do rotating lift movement, the handwheel is fixed at the top of the valve stem. When the handwheel is rotated clockwise, the stem threads are rotated downward, the valve sealing surface and the valve seat sealing surface are in close contact, and the globe valve reaches the closed state; when the handwheel is rotated counterclockwise, the stem threads are rotated upward, and the valve sealing surface and the valve seat sealing surface are disengaged, and the globe valve opens
The body is the main structure of the valve that keeps everything together. This part contains all internal parts of the globe valve to allow the control of the substance that needs regulation. The opening of the body contains ports (usually two or three ports) to enable the movement of the fluid to the inside or outside of the globe valve.
The seat is among other globe valve parts that seal the space between the disk/stem and bonnet. The seat ring can be screwed into the valve or torqued. The seat is also known as a seat ring and provides a shutoff surface that's stable and also replaceable. Seat rings can hold the cage firmly to the body of the valve.
The bonnet is one of the outer globe valve parts that's connected to the body to provide a leak-proof closure. There are different bonnet types such as bolted, screw-in, or union bonnet that are used in different globe valves. Each of these bonnet types has its own advantages. For example, the union bonnet not only adds strength to the body but is also great for applications that need regular cleaning or inspection. The screw-in bonnet with its simple design offers a pressure-tight seal. And the last bonnet type, the bolted bonnets that are attached with bolts are great for higher pressures.
The stem is part of the globe valve that connects the disk to the handwheel or the valve actuator to transmit the actuation force. Since it connects the actuator to the parts inside of the globe valve, it is considered as one of the critical globe valve parts. If the valves are controlled by actuators, the stem is smooth but for the manual valves, they are threaded.
The ends of smooth steam are threaded allowing the connection to the actuator and the plug. A wearable packing surrounds the smooth stem to prevent leaking material from the valve. So, the packing should be replaced regularly in the maintenance period. The stem can withstand a large amount of compression force in the closure state. And when the valve is opening, it has high tensile strength.
The plug or the disk is among the essential globe valve parts. It moves perpendicular to the seat and its movement can block or free the flow since it works as a moveable physical barrier. When the valve is closed, the plug sits against the seat to block the flow and when it sits above the seats. it enables the flow of the material.
Different disk arrangements have been designed for globe valves such as composite type, ball type, and needle type. The composite disk can provide a better shut-off, while the ball type is used for low-temperature and low-pressure systems. The needle disk has the advantage of providing a better throttling compared to the other two.
