JIS10K Flange End Gate Valve
JIS10K flange end gate valves are gate valve made in accordance with ASME B16.10/API 600/API 602. It is designed with a wheel shape handle and the metal to metal seat sealing characteristics. The flange end gate valve consists of a closure element, called a wedge which is allowed to permit and prevent the flow of a process fluids.
There are some special flange end gate valve to meet some hydraulic system requirement, for example F7364 gate valve. JIS10K F7364 flange end gate valves are marine grade gate valve made in accordance with F7364. For marine grade gate valve, it's body size is bigger and weight is heavier compare to standard design of JIS flange end gate valve.

JIS10K Flange End Gate Valve Product Information
Gate valve is used to allow or cut off the fluids flow through along hydraulic system. By rotate the wheel handle to open or close position which mark on it, the wedge will be lift up or lift down. It is design and manufacture according to ASME B16.10/API 600/API 602/F7364 standard. It will be inspected and tested according to JIS F7400/API 598.
Material and Design:
JIS10K flange end gate valve is available in stainless steel SS316 material or cast iron material. It all come with bolted bonnet, however there are different in shape due to different design standard. Bolted bonnet type is where a bonnet is attached on valve body to hold the internal parts that into it with screw and nut.
The stem, one of the important component in gate valve, is available in two type: rising stem or non-rising stem. For rising stem gate valve, the stem will go up when we rotate the handle to open position and go down when we rotate the handle to close position. It can be easily tell if the valve is in open or close position when we looking at the amount of stem exposed. For non-rising stem gate valve, the valve is in open position when the handle is rotate as far as possible to "open" direction that mark on handle and in close position when the handle is rotate as far as possible to "close" direction that mark on handle. Non-rising stem gate valve usually been used on tight places where there is not enough space for the stem to raise, such as underground hydraulic systems.
Do check with us for the availability of gate valve design.
The size for JIS10K gate valve is ranged from 1" to 6", subject to material. JIS10K series flange end gate valve can withstand up to 10 kg/cm² which is equivalent to 150 PSI working pressure.
For flange end gate valve, the another connection end must be flange end too. The number of bolt hole is depend on the valve size too. There will be 4 bolt hole for size below 4", 8 bolt hole for size above 4". Gasket, bolts and nuts are required to connect the valve body flange to another flange end.

For JIS 10K cast iron gate valves, there are two size ranges which are from 2 inches to 4 inches and from 5 inches to 6 inches.
For JIS 10K cast iron gate valves, the working temperature ranges are ≤ 205°C (for 2"- 4") and ≤ 429°C (for 5"- 6").
