Stainless steel valve-API602/API600/API6D-gate,globe,check,ball valve
A stainless steel valve is a valve, mainly made of stainless steel, which regulates the flow of a fluid, corrosive or noncorrosive (fluidized solids, slurries, gases, liquids,) by opening, closing, or partially obstructing various passageways. It is a pipeline fluid distribution system control unit, is used to change the channel cross-section and media flow direction for fluid guidance, regulating, cut-off, throttling, stopping and depressurization through diversion or excess flow.
There are many kinds of fluid control valves with various specifications, such as cut-off valves with simplest structure and valves with highly complex automatic control system, minute gauge valves and valves with 10m nominal diameter for industrial pipes.
The types of stainless steel used for valve body are typically appear with CF8, CF3, CF8M and CF3M(or their relevant forge material 304, 316, 304l,316l) these austenitic stainless steel and other special stainless steel include Duplex, Moniel, Inconel and so on.
here are kinds of the stainless steel valves divided by their structure, such as stainless steel gate valve, check valve, globe valve, ball valve, butterfly valve, plug valve, safety valve, baiting valve, steam trap, needle valve, strainer, air-operated valve and so on.
Stainless steel valve has their application scope:
Its application medium: water, steam, oil, gas, mud, all kinds of corrosive media, liquid metal and radioactive fluid , micro-alkyl, methane, ethane, fresh, ethane, …liquid heavy component ,hydrogenated liquid and so on;
Its Working temperature:-269℃~1430℃;
Its working pressure: 0.0013Mpa~1000Mpa;
It can be operated by many means: such as manual, worm gear, hydraulic, pneumatic, electric, electro-magnetic action, electric-hydraulic, pneumatic-hydraulic, electro-magnetic-hydraulic, spur-gears-drive and umbrella-gear-drive etc. It can react to pressure, temperature or other as required or start or stop without instruction of those sensing signals. Besides, the valve relies on drivers or automatic parts to enable gate parts lifting, sliding, rotating pendulum, rotation, thereby changes the area of the flow channel.
Due to stainless steel have good performance in temperature-dependent yield strength, usually stainless steel valve can have more thin thickness compare with other carbon steel valve like API600 or API6D. For SGV general and traditional steel gate globe check ball valve, we offer more choice for guest. We have our own mold special design for API603 standard to meet client’s specific requirement to reach highest cost performance.
Corrosion-Resistant, Bolted Bonnet Gate Valves – Flanged and Butt-Welding Ends. The standard covers corrosion-resistant bolted bonnet gate valves with flanged or butt-weld ends in sizes NPS 1/2 through 24, corresponding to nominal pipe sizes in ASME B36.10M, and Classes 150, 300, and, 600, as specified in ASME B16.34.
Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries – Modified National Adoption of ISO 10434
API SPEC 6D
Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.
