Bellows globe valve
Adopts a unique bellows seal design and adopts double combined sealing. Double-layer stainless steel bellows is used as the valve stem sealing element, and graphite packing is used as the secondary auxiliary seal, which can effectively solve the problem of valve stem packing sealing. Leakage problem, can meet the most stringent leakage level requirements. It reduces maintenance costs and frequent maintenance, and also provides a clean and safe working environment.
Bellows globe valves are available in diameters ranging from ~ to cast iron, ductile iron, cast steel and stainless steel to meet the requirements of different fluids and working environments. Connection standards include flange, thread and socket welding, etc., and pressure levels include,,. The maximum temperature resistance can reach ℃, and it can be used in high temperature systems. A single valve can meet the requirements of various industrial applications and ensure a long service life, maintenance-free and robustness.
Bellows globe valve performance characteristics and model introduction
Performance characteristics
Long-term stable and reliable operation
Equipped with a throttle valve core, double bellows seal, longer life.
, Double seal, super sealing performance
Use double seal composed of double-layer stainless steel bellows seal and graphite packing to prevent leakage.
, Flat seal, eliminate leakage
The flat seal form between the valve disc and the valve seat further ensures the high reliability of the dynamic and static sealing performance at the valve stem, allowing it to perform well in various orientations Produces excellent sealing performance.
, Save operating costs
The zero leakage feature improves the safety of the system, saves energy, reduces maintenance costs, and provides users with a clean and safe working environment.
, Simple and convenient operation, no special maintenance required
Short closing stroke, short reaction time, no lifting of the hand wheel, it can open and close freely even in a small space, the valve stem lifting position display makes the operation more convenient. The double-layer bellows sealing structure prevents leakage and requires no special maintenance.
