Mart Flow Control Valves

Globe valves are made with a globe like structure that has a plug inside it to open and close the circulation. The globe valves are different from the ball valves. The ball valves have balls that turn around to open and close the system while the Globe Control Valves have a plug that descents into the opening in the metal structure inside the body. There are different parts to the valve and they are made up of different materials and of different sizes. The seat and seating material requirements vary for different types of Globe Check Valves based on their grades, standards and specifications.  The trim material varies as well. The materials can be 410, 316, alloy 20 or 304 grade of steel among many others used for this purpose.
The Api 623 Globe Valves can come with metal ring joint, spiral wound gasket with filler and corrugated metal with graphite facings for the gasket part of it. The API 623 valves are usually larger diameter valves used in high fluid flow systems. Though the valves are called globe valves, many valves do not necessarily have globe shape body to qualify as globe valves. The valve sizes can range from 2 inches to 18 inches and more in diameter in general. There are pressure classes ranging from class 150 to class 2500 in the Actuated Globe Valves. These are used in systems where vibration, cavitation and leakages are prone because this type of valve eliminate the possibilities of these effects.

Type of Globe Valves

• Flange Globe Valves
• High Pressure Globe Valves
• Bellow Seal Globe Valves
• Forged Steel Globe Valves
• Angle Globe Valves
• Globe Check Valves
• Three-Way Globe Valves

Flange Globe Valves

• Swivel Plug Disc
• Size Range: 2" to 24"
• Pressure Range: 150# to 2500#
• Design STD.: API 600/ ASME B16.34
• Flange Globe Valve Manufacturer

The disc of globe valves moves along the centreline of the seat. These valves generally used for the modulating to flow. This is happened because of change of the stroke of valve flap proportional to seat port. Due to small change of stem stroke, it shows smooth control that is the reason globe valve widely used to regulate the flow. Thus, the globe valve is more suitable for shutting-off or regulating and throttling.

The working principle and characteristics of the globe valve:

The globe valve allows tight shut-off and smooth regulating of the flow. There is a torque applied via stem on valve seat area. This torque varies as per required flow so the valve used for application where flow regulating or zero leakage required.It is easy in manufacturing, assembly and maintenance.

High Pressure Globe Valves

• Globe Valve
• Pressure Seal Bonnet
• Size Range: 2" to 24"
• Class Range: 900# to 2500#
• Design STD.: API600/ ASME B16.34
• High Pressure Globe Valve Manufacturer

The stem extends toward the end of the disk from the bonnet in the high-pressure globe valve. In this operation condition a sealing ring parallel to the shape of the gap is provided in the annular gap formed between the cone of the inverted cone on the stuffing box, the inner hole of the valve body and the bonnet face the end face of the high-pressure globe valve. In this mechanism the use of the pressure of the liquid medium itself to achieve the purpose of sealing, the greater the pressure, the larger the sealing force, the more reliable the sealing, making it a pressure seal globe valve.The sealing performance is very good under high pressure and temperature condition even if fluctuation is noted. Compared with the forced sealing, it does not require a large bolt preload.

The main features of the high-pressure globe valve:

• Temperature range: -40℃– 550℃
• Body material: carbon steel, stainless steel (Also other material available on request)
• Stem material: stainless steel
• Packing: flexible graphite, reinforced Teflon
• Connection: flange, butt welding
• Suitable media: water, steam, oil, etc.

 

Bellow Seal Globe Valves

• Globe Valve
• Low Fugitive Emission
• Size Range: DN15 to DN500
• Class Range: PN10 to PN40, 150# to 600#
• Design STD.: EN558-1
• Bellow Seal Globe Valve Manufacturer

To handle the hazardous fluids, the industries use a Bellows sealed Valve. It is a specially designed valve suitable for use such industries. The bellows sealed valves does not allow any leakage. In the era of chemical and nuclear industries, there are extremely poisonous and toxic media flowing through the pipeline. It may cause very high loss of money and casualty of life. So, the pressure sealed valves are used in such pipes and systems have specific stringent leakage and sealing requirements.The bellow seal globe valves are the necessities of a completely different & desired sealing.

Forged Steel Globe Valves

• Forge Valve
• Size Range: 1/2" to 4"
• Pressure Range: 150# to 2500#
• Design STD.: API602
• Test STD.: API598
• Forged Steel Globe Valve Manufacturer

There are three types of bonnet design for forged steel globe valve.
