The operating interface, access opening and any extension arrangement must be checked together. A similar-looking key or the same nominal valve size does not establish compatibility.

Measure depth and access before ordering

Provide the valve elevation, burial or chamber depth, operating opening and insertion path. Tool length, connections, support and protection depend on the actual installation; arbitrary extension lengths are not treated as confirmed supply capability.

Check the JIS flange interface completely

Confirm nominal size, pressure designation, facing, bolt pattern and face-to-face dimension. JIS 10K alone does not establish interchangeability or the allowable pressure at every temperature.

Specify the actual material and service

The catalogue title lists SCS13 and SCPH2 options. Confirm the required body material, trim, medium, working temperature and pressure for the ordered configuration; the title is not evidence that every material combination is interchangeable.

Buyer questions

Can I operate this valve from ground level?

Confirm the valve depth, access opening, tool length, interface and available operating space. Ground-level operation depends on a compatible complete arrangement.

Can I reuse my existing underground valve key?

Only after checking the tool-end dimensions, coupling, effective length and operating requirements against the valve interface. Send photographs and dimensioned drawings for verification.

Can any JIS 10K gate valve replace the old one?

No. Check size, flange details, face-to-face dimension, material, operating clearance and service conditions. The pressure designation alone does not prove interchangeability.

Prepare a quotation for this valve

For underground gate-valve replacement, match the key/tool and access geometry as well as the JIS flange interface.

Access: Valve elevation, chamber or burial depth, insertion path, access opening and measurement datums.
Interface: Size, JIS flange/facing and bolt details, face-to-face length and tool-end dimensions.
Materials and duty: Requested body/trim materials, fluid, temperature/pressure and isolation requirements.

Documents to agree before supply

Order-specific valve and operating-tool drawing
Confirmed material and pressure-temperature information
Installation, inspection and maintenance requirements for the supplied arrangement

Ask which documents are available for the offered configuration and agree their scope before supply. A catalogue picture is not a certified drawing or test report.
