Introduce a double block and bleed valve's structure and working principle.The valve is superior to common gate and ball valves in terms of its sealing performance and service life.The valve has the functions of being fireproof, on-line maintenance, double block and bleed, cavity pressure relief, internal leak detection and others. Illustrate the double block and bleed valve's functions and applications in the oil and gas storage and transportation systems in combination with examples, which has opened new development potential for process design of oil and gas storage and transportation systems and solved many problems encountered in pipeline design. It has not only optimized the pipeline design and improved the product quality but also saved the pipeline operation costs.More products
Inverted pressure balance lubricated plug valve acc. to ANSI is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc under nominal pressure of CLASS150-2500LBS and working temperature of-29-180°C.More products
It is a valve used to control the flow of fluids. It opens and closes the flow channel by rotating the valve body to adjust the flow of the medium or cut off the fluid. This type of plug valve is characterized by a metal sealing design, high sealing performance and strong corrosion and wear resistance, and is suitable for high temperature, high pressure and highly corrosive media.More products
Sleeve type soft sealing plug valve acc. to ANSI is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc under nominal pressure of CLASS150-900LBS, and working temperature of- 29-180°C.More products
Elastic seat ring sealed eccentric plug valve is a new structure valve which fills the blank of traditional plunger valve and ball valve in the applications like large- diameter pipeline (above DN200] and muddy water and sludge occasions. Owing to its excellent sealing performance and corrosion-resisting performance, smaller opening/closing torque and water-flow loss and long service life, it is applied as the regulator or closure in the work occasions such as urban sewage, industrial sewage, sludge and clear water.More products
3 way plug valve is applicable to change the media flowing direction or to distribute the media, that are used in various industries such as, petroleum, chemical industry, pharmacy, chemical fertilizer, power. Industry etc. under nominal pressure class 150-900LBS, PN1.0-16.0, Working temperature- 29°C~550°C.More products
API Jacketed Plug Valve is a very practical valve, especially suitable for fluid control occasions with extreme temperatures or where precise temperature control is required. Its design combines the features of jacket and plug valve. This product can be used in chemical, petroleum, natural gas, high viscosity fluid control and cryogenic fluid, etc.More products
