Specialityvalve is best Bellow Seal Valve Manufacturer in India. A Bellow Sealed Valve is an industrial process valve that prevents valves from leaking. It's also known as a leak-free valve or an emission-free valve. External leakage is considerably decreased when a bellow Sealed valve is employed. The use of bellows to cover the valve stem decreases leakage from gland components.
It is a control valve with a bellow cartridge that is welded to the bonnet and valve stem instead of the traditional packing. The bellows can be compared to a coil spring because it can bend when it is compressed or stretched. The only difference between a globe valve and a bellows valve is that a globe valve has packing along the stem, but a bellows seal valve has bellows instead of packing to prevent leakage. These valves are absolutely tight and can handle caustic substances without any problems. The butadiene extraction unit contains these valves.

What is a Globe Valve?
Specialityvalve also manufactures Globe Valves. Using a disc as a closing component, the Globe Valve is mainly designed to stop, start, and control flow. Globe valves are ideal for throttling and regulating fluid flow, and are commonly used in compact pipe systems. The disc can either be totally removed from the route or completely closed.
