The valve disc of the ultra-low temperature 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.
RAYS C-type Wear-Resistant Ball Valve is a valve designed for harsh working conditions, with many unique design features and advantages. It achieves low friction and high reliability media control through its unique eccentric design and metal-to-metal seal, and is suitable for a variety of harsh industrial application environments. The C-type wear-resistant ball valve adopts an eccentric design, so that the C ball gradually enters the valve seat when the valve is closed, and the C ball instantly leaves the valve seat when the valve is opened, thereby reducing the resistance of the switch action. This design also makes the C ball and the valve seat have no contact after the valve is opened, reducing friction and wear.
It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
