Relia Valve is an industrial valve manufacturer and exporter in China; most of our valves are exported to overseas markets. Our company covers an area of &#;and has introduced the world's advanced valve manufacturing equipment.
With competitive price and timely delivery, Xiangyu sincerely hope to be your supplier and partner.
The main products are Ball Valves, Gate Valves, Globe Valves and Check Valves. Main body materials include carbon steel, stainless steel, low-temperature carbon steel, duplex stainless steel, aluminium bronze, Hastelloy C, Monel, Inconel 625, Inconel 825, etc. Size: 1/2 "~40", pressure rating: Class 150LB~LB, end connection: flanged, welded, hub end and thread etc. The valves are used in petroleum, chemical, electric power, natural gas, coal chemical industry, aerospace, metallurgy, pulp & paper, etc.
All the valves are strictly designed and tested according to international standards such as API, ANSI, ASTM and ASME. 100% of the valves are hydro-tested to meet the standard and customer request before leaving our valve factory.
Our quality control verifies all processes from material receipt to final customer inspection. All products are supplied with certified test reports, which include chemical analysis, physical analysis and hydrostatic pressure tests.
Pressure TestingAll valves are high-pressure hydrostatic tested on the valve body and seat, and low-pressure air is tested on the seat to relevant shut-off class. Testing is performed to API 598, API 6D, or another applicable standard such as MSS. Furthermore, all valves are visually inspected to MSS-SP55.
Dimension TestingThe valve parts are dimension tested before assembly as per the drawing to ensure that the valves meet the best performance. The valve dimensions are checked according to the GA drawing after the assembly.

Special TestingSpecial product testing includes high-pressure gas testing, low-temperature cryogenic testing, body and stem helium leakage testing, endurance testing, bending testing and high-temperature testing. Other specifically dedicated procedures are available and can be performed on request according to our customers' specifications.
Valves are mechanical devices that control the flow and pressure within a system or process. They are essential piping system components that convey liquids, gases, vapours, slurries, etc.
A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word "valve" is derived from the Latin valva, the moving part of a door.
Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
