Flange RF End Manual Forged SUS304 Stainless Steel 300lb 2 Inch DN50 Pn16 Globe Stop Valve

Flange RF End Manual Forged SUS304 Stainless Steel 300lb 2 Inch DN50 Pn16 Globe Stop Valve

This heavy duty class 800 forged carbon steel Globe Valve is suitable for demanding process applications and industries where the isolation of steam, gas or liquid is required.

The valve designed to API602 and tested to API598 has an outside screw and yolk with rising stem. The handwheel operates the globe valve for both isolation and for throttling applications.

Why use globe valves: these valves provide a positive tight shut off in the horizontal or vertical position for process fluids in pipelines. They also offer a small amount of control and are used to throttle steam, gas or liquids. Easy to operate and the preferred choice over ball valves by engineers to isolate trapping stations.

To understand the working of a globe valve, one should understand how the disc and seat of the valve are positioned. The disc inside the valve is movable whereas the seat is stationary and is in a spherical body. The seat is parallel to the pipe and perpendicular to the disc.

The disc of the valve will move up and down according to the actuation of the wheel on the top of the valve. The wheel can be moved either manually or through an actuator - when it is moved, the disc rises and falls as it is attached to the valve stem. To stop the flow completely, the disc is fully seated on the seat ring. To resume flow, the disc is lifted up.

Throttling and controlling of flow can be done by adjusting the position of the disc as per need.

If the case is so that the globe valve is operated in low-temperature situations, then the valve is installed in such a way that the pressure falls under the disc. For high-temperature situations, like boilers that work in steam, the valves are positioned to handle pressure above the disc.

No matter what type of globe valve you have, there are several key parts that all globe valves contain: body, seat ring, cage, bonnet, stem, plug (disk), yoke, yoke nut, back seat, packing, and valve Actuator.
 

Body

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.

Seat Ring

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.

Bonnet

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.

Stem

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.

Plug (Disk)

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.
