●Excellent sealing performance: The bellows globe valve adopts a bellows sealed design, completely eliminating the disadvantages of aging and easy leakage of ordinary valve stem packing seals, ensuring zero leakage of the valve stem.
●Long service life: The corrugated tube has a long fatigue life, and all parts are made of high-quality materials, which are wear-resistant and corrosion-resistant, reducing maintenance frequency and suitable for frequent opening and closing scenarios.
●Easy to operate: The handwheel adopts ergonomic design, with a longer service life and easy and convenient operation. There is no lifting handwheel and position indicator ("+" "-"), making the operation more intuitive. At the same time, the valve cap is equipped with a locking nut, which can fix the valve opening in a certain position.
●High temperature and high pressure resistance: The working temperature range is wide, such as -196 ℃~560 ℃, and the pressure range is large, such as 150~2500LB, suitable for various high temperature, high pressure, and impact conditions.
●Widely applicable media: It can be used for pipelines containing steam, flammable, explosive, thermal oil, high-purity, toxic and other media, meeting the various working conditions of industries such as petroleum, chemical, pharmaceutical, fertilizer, and power.
●Compact and reasonable structure: Compact structure, low flow resistance, space saving, easy installation.

The valve disc of the Cryogenic Swing Check Valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
Self-operated Temperature Regulator is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
