PRODUCT CONFIGURATION
Materials & components
Define the pressure-containing materials, sealing surfaces and stem system for your service conditions.
| Component | Selection requirements |
|---|---|
| Body & bonnet | Specify the body material grade for the design pressure, temperature and medium. |
| Wedge & seat rings | Metal-to-metal sealing; specify the sealing-surface material and any hard-facing requirement. |
| Stem | Select stem material for the medium, corrosion resistance and operating temperature. |
| Stem nut | Specify the stem-nut material and operating arrangement. |
| Packing & bonnet gasket | Select the packing and gasket system for the specified temperature and medium. |
| Handwheel & fasteners | Confirm the operating torque, access space and fastener requirements. |
RUSSIAN-STANDARD PROJECTS
GOST interfaces & acceptance requirements
Include the applicable standard, pressure class and inspection requirements when specifying your valve.
| Requirement | Enquiry details |
|---|---|
| Flange interface | For GOST 33259 projects, specify pressure class, bolt drilling and sealing-face execution. |
| Seat tightness | Specify the required leakage class and acceptance criteria with reference to GOST 9544. |
| Operating conditions | Provide the working medium, design pressure and minimum/maximum temperature. |
| Material specification | Identify the required Russian material grade or an agreed equivalent for each pressure-containing part. |
| Inspection documents | Specify the material certificates and pressure/seat test records required by the project. |
CONNECTION & DIMENSIONS
Match the valve to your pipeline
Rated pressure: PN16. Temperature limits, material grades and connection dimensions are agreed for the selected configuration.
| Item | Dimensional requirements |
|---|---|
| Nominal size | DN50–DN600 |
| Face-to-face length | State the required installation length L or provide the mating-pipeline drawing. |
| Flange connection | Provide outside diameter, bolt-circle diameter, bolt-hole count/diameter and sealing-face type. |
| Overall envelope | Confirm closed/open height, handwheel diameter and access space. |
| Final drawing | Request the configuration-specific outline and connection drawing with your enquiry. |
