Bellows Globe Valve

Highlight: Bellows Globe Valve

Product introduction:

Bellows-sealed gate valves, also known as bellows-packaged gate valves, form a metallic barrier between the fluid medium and the atmosphere through automated roll welding, ensuring zero stem leakage. The valve stem features a dual-sealing structure combining bellows and packing, guaranteeing leak-proof sealing, particularly suitable for pipelines carrying flammable, explosive, toxic, or valuable media. The bellows are crafted from stainless steel or Inconel, with a scientifically designed structure that resists fatigue and ensures extended service life.

Product technical parameters:

Nominal Pressure PN(MPa)		1.0 - 4.0
Nominal Diameter DN(mm)		15～600
Test pressure (MPa)	Strength (water)	1.5 times of pressure nominal
	Sealing (water)	1.1 times of pressure nominal
	Sealing (Air)	0.6 times of pressure nominal
	Sealing for bellows (water)	1.5 times of pressure nominal
Raw material		WCB, CF8, CF8M
Medium suitable:		Water, steam, oil mediums
Working temperature		-196℃～600℃
Connection type		Flange
Operational method		Hand-wheel, bevel gear, pneumatic and electric actuators

Product features:

For the bellows globe valve, its key component is the metal bellows. The lower end is automatically roll-welded to the valve stem assembly, and the upper end is automatically roll-welded to the connecting plate, forming a metal barrier between the fluid medium and the atmosphere to ensure zero stem leakage.
The valve disc adopts a conical design, and the sealing surface is streamlined with the medium, resulting in better sealing performance and longer service life.
The dual-sealing design (bellows + packing) ensures that if the bellows fail, the valve stem packing will also prevent leakage, complying with international sealing standards.
The valve cover is equipped with a grease nipple, allowing direct lubrication of the valve stem, nut, and bushing. Traditional globe valves can only lubricate threads.
The ergonomic handwheel design features a longer service life, easy and convenient operation, and greater safety and reliability.
