◎Excellent sealing performance, using metal bellows as the key sealing component, with its lower end welded to the valve stem assembly and its upper end connected to the
Plate welding forms a metal barrier to prevent fluid medium leakage and achieve zero
leakage of the valve stem
◎The main components such as the valve body are made of forged steel with high structural strength, resulting in a more uniform structure, better density and strength integrity, and dimensional errors small, with better performance compared to castings, able to withstand higher pressure and temperature
◎ Easy and reliable operation
The dual guarantee of long service life with corrugated pipe sealing and packing sealing
reduces the risk of leakage and lowers the frequency of maintenance; Valve body and
◎The minimum wall thickness design of the valve cover meets the requirements of relevant standards, ensuring the strength and rigidity of the valve under harsh working conditions such as high temperature and high pressure

RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
Side Entry Cryogenic Trunnion Mounted Ball Valve and extended valve cap ball valves will bring you huge profits in the field of low-temperature LNG services. Use temperature range-196°C~+150°C, with an extended valve cover design.
