Bellows globe valve is made of new non-metallic materials. It can withstand long-term high temperature and high pressure without losing elasticity. Moreover, the contact area between plunger and sealing ring is large. The sealing ring is made of mixed materials with good performance, reliable sealing and durable. It is mainly used in metallurgy, electric power, chemical industry, oil refining, chemical fertilizer, light industry, food and other industries.

Structural features

1. the product structure is reasonable, reliable sealing, excellent performance, beautiful shape.
2. Sealing surface surfacing CO based cemented carbide, wear resistance, corrosion resistance, abrasion resistance, long service life.
3. the valve stem by quenching and surface nitriding treatment, has good corrosion resistance and abrasion resistance.
4. the valve is equipped with inverted sealing structure, sealing is reliable.
5. the parts material and flange size can be reasonably selected according to the actual working conditions or user requirements, to meet various engineering needs.

Welded bellows globe valves are used in steam systems, natural gas, toxic waste gas purification, vacuum units, hot oil systems, heating equipment, refrigeration systems, ammonia, hot water, power stations, etc.

Structural features

1. Double sealing design (bellows + packing) If bellows fail, stem packing can be avoided.
2. Reasonable structure, reliable sealing, excellent performance, beautiful shape.
3. No fluid loss, reduce energy loss and improve plant equipment safety.
4. Sealing surface surfacing of CO based cemented carbide, wear resistance, corrosion resistance, good friction resistance, long service life, reduce the number of maintenance, reduce operating costs.
5. Rigid and durable bellows seal design ensures zero leakage of valve stem and provides conditions without maintenance.
6. Stop valve stem quenching and surface nitriding treatment, with good anti-corrosion and anti-friction properties;
7. Stem lifting position indication is more intuitive.

The bevel bellows globe valve adopts double sealing design (bellows + packing) if the bellows fail, the bevel bellows globe valve stem quenching and surface nitriding treatment, has good anti-corrosion and anti-friction performance;The rugged bellows seal design of the bevel bellows globe valve ensures zero leakage of the stem and provides maintenance-free conditions.
