Wafer Type Construction
The wafer construction is designed for sandwich installation between compatible pipeline flanges. This provides a compact valve arrangement for suitable industrial piping systems.
The specified flange compatibility includes BS 10 Tables D, E, F and H, DIN, PN 10, PN 16, PN 25, PN 40, ASA 150, ASA 300, IS 778, IS 6392 Table 17 and IS 1538.
Flange dimensions, pressure class, bolt arrangement and pipeline compatibility should be verified before installation.
S.S 304 Disc
The disc is manufactured from stainless steel and specified as IS 3444 Grade 1 / ASTM A 351 Grade CF8, corresponding to the S.S 304 / CF8 configuration.
The stainless-steel disc is accurately guided between the upper and lower stems and forms the primary rotating flow-control component.
The disc material should be evaluated against the actual pipeline medium, pressure and temperature before selecting the valve for a specific application.
S.G. Iron Body
The valve body is manufactured from S.G. Iron according to IS 1865 Grade 400/15. The body provides the structural housing for the disc, stems, lining and operating assembly.
Body material selection should be considered together with the pipeline medium and operating conditions.
Gear Operated Mechanism
The valve uses a gear box assembly for manual operation. The gear mechanism is connected to a sheet-metal handwheel and provides controlled operation of the valve.
Gear operation can be useful where controlled manual operation is required for the selected valve size or pipeline application.
The operating mechanism should be used within the applicable product specifications and installation requirements.
Two-Piece Stem Design
The valve incorporates upper and lower stainless-steel stems. The stems are manufactured according to IS 6603 Grade 12 Cr12 and are precisely guided through the specified bush arrangement.
The two-piece stem configuration connects the operating mechanism with the stainless-steel disc.
Body Lining
The valve uses integrally moulded rubber lining to provide seating to the disc and sealing at the stem and matching pipe flange connection.
EPDM and Nitrile are specified lining options. Neoprene, Viton and Silicon lining configurations can also be provided according to requirement.
Lining selection should be based on the actual pipeline medium, chemical compatibility, pressure and temperature requirements.
Pressure and Temperature Rating
The valve has a PN 2.5 pressure rating with a maximum working pressure of 2.5 MPa.
The specified hydrostatic shell test pressure is 3.75 MPa and the seat hydrostatic test pressure is 2.75 MPa.
The maximum specified working temperature is 90°C. These values should be considered when evaluating the valve for a specific service condition.
Suitable Media
The supplied technical source specifies this valve for suitable systems handling steam, water, oil, air and gases.
- Steam
- Water
- Oil
- Air
- Gases
Final selection should always consider the actual medium and compatibility of the body, disc and lining materials.
