Advantages of GLobe Valve
- Compared with the gate valve, the globe valve structure is simpler, usually only one sealing surface on the valve body and valve flap, small sealing area, saving valuable materials, low cost, and therefore better manufacturing process, easy maintenance.
- The seal surface wear and abrasion are light, good sealing. No relative sliding between the valve flap and body sealing surface when opening and closing (except for the conical sealing surface), so the wear and abrasion are not serious, good sealing performance, and long service life.
- Opening height is small, generally only 1/4 of the diameter of the valve seat channel, compact structure, saving installation space.
- Precise flow control: Globe valves are particularly useful for applications that require precise control of fluid flow. They can be adjusted to provide a wide range of flow rates, making them suitable for a variety of industrial applications.
- High-pressure rating: Globe valves can handle high-pressure applications because of their unique design. This makes them ideal for use in piping systems where pressure is a critical factor.
- Good shutoff capability: Globe valves have a good shutoff capability, which is particularly useful in applications where tight shut-off is required. This helps ensure that the valve prevents the flow of fluids in both directions.
- Versatility: Globe valves can be used with a wide range of fluids, including gases, liquids, and slurries. This makes them useful in a variety of industries, including petrochemical, manufacturing, refining, and water treatment.
- Long lifespan: Globe valves are durable and can last for many years with proper maintenance, which can save money over the long term. They are also less prone to leakage, which can prevent damage to equipment or surrounding areas.
Understanding the Construction of Globe Valve
Globe Valves consists of three main parts: body, Bonnet, and trim. The body is generally connected to other equipment by means of flanged, screwed or welded connections. The Bonnet, which containing the moving parts, is attached to the body, usually with bolts, to permit maintenance. The Valve trim consists of the stem, the disc and the seat rings.

1. OPERATOR | The spoked handwheel is fabricated from steel pipe. The hub has a square hole for coupling with the stem, and for large sizes the hube is coupled with the yoke sleeve by means of a tongue. |
---|---|
2. GLAND AND FLANGE | They are in forged steel and are supplied in two pieces, self aligning design in order to allow the gland to slide parallel to the stem even if the eyebolts are unevenly tightened. |
3. GLAND BOLTS AND NUTS | The forged steel gland bolts are of the eyebolt type which can be swung outward for ease of gland repacking. They are fixed to the bonnet by hinge pins. |
4. BONNET BOLTING | Bonnet studs and nuts are manufactured from alloy steel to the relevant ASTM standard. The body to bonnet connection is designed according to ASME VIII DIV 1 standard. |
5. BODY | The body is in carbon or stainless steel and is also available in many other CRA. It is carefully designed for total reliability and simple maintenance. The basic dimension, i.e. wall thickness, face to face and flanges comply with the relevant BS and ASME standards. The body-to-bonnet flange is circular. The body-to-bonnet joint are male-and-female on Class 150 and 300 and ring joint on Class 600 and above. The body is basically supplied with renewable seats. Bosses are provided for draining connections. |
6. BONNET | As the body, the bonnet is in carbon or stainless steel and is available in many other CRA. It is machined to accept yoke sleeve and incorporates a stuffing box sized in accordance with the BS standard. Lifting lugs can be provided integrally cast on the bonnet surface. |
7. BONNET BUSHING | The bonnet bushing or backseat is part of the valve trim. Its design allows valve repacking without valve’s bleeding or draining. Hardfacing can be provided on stem seating surface. |
8. STEM | The stem is part of the trim and is available in a wide range of material in accordance to BS1873, API 600 or customer’s requirements. The stem is provided with a ground backseat in order to ensure a perfectly tight seal to the stuffing box when the valve is fully open. The stem is highly finished in order to minimize friction and prevent damage to the packing. The thread is trapezoidal ACME type. All the stem sizes comply with the BS 1873 standard. |
9. SEAT RINGS | Threaded and seal-welded seat ring is supplied as a standard. The seats are part of the trim of the valve. They can be simply threaded for easy installation and dismantling. Special attention is given to the seating surface which is ground and lapped for a tight seal. |
10. DISC | The disc is the main part of the trim. It is connected to the stem by means of a swiveling half rings coupling and is guided in the body from 4” and above. The standard sealing profile is a spherical surface seating against a conical seat. If required a conical to conical seating can be supplied, and for flow throttling operations a regulating disc is adopted, shaped in order to give a linear opening. The stop check execution shows an externally guided disc, disconnected from the stem. A cladding or lining can be applied to larger discs to improve its resistance against erosive and corrosive environments. |
