Butterfly Valve (Wafer Type), PN 2.5 with S.S 304 Disc
Butterfly Valve (Wafer Type), PN 2.5 with S.S 304 Disc is designed for suitable industrial pipeline applications requiring flow isolation and control. Its wafer construction allows installation between compatible pipe flanges while maintaining a compact pipeline valve arrangement.
The valve uses an S.G. Iron body with a stainless-steel disc. The disc is accurately guided between two stainless-steel stems, while the lever-operated mechanism provides manual control of the valve position.
The integrally moulded rubber lining provides seating for the disc and contributes to sealing around the stem and matching pipe flange connection.

Wafer Type Construction
The wafer design allows the valve to be installed between compatible pipeline flanges. This provides a compact installation arrangement for suitable industrial piping systems.
Before installation, customers should verify the pipeline size, flange standard, pressure class, bolt arrangement and available installation space.
S.G. Iron Body
The valve body is manufactured from S.G. Iron according to IS 1865 Grade 400/15. The body houses the disc, stems, lining and operating components.
The body material should be considered together with the operating medium, pressure, temperature and overall pipeline conditions when selecting the valve.
S.S 304 Disc
The disc is manufactured from stainless steel and specified as S.S 304 / CF8 according to IS 3444 Grade 1 / ASTM A 351 Grade CF8. The disc is accurately guided between the upper and lower stainless-steel stems.
The stainless-steel disc configuration provides a different material combination from standard S.G. Iron disc configurations and can be selected where the application requires a stainless-steel disc, subject to service compatibility.
Lever Operation
The valve is manually operated through a flow-control lever and notch plate. This arrangement allows the operator to adjust the valve position according to the required flow isolation or control application.
A padlock arrangement, limit switch and gear arrangement can also be provided according to the applicable configuration and requirement.
Two-Piece Stem Design
The valve incorporates a two-piece stem design using stainless-steel upper and lower stems. The stems are precisely guided through the specified PTFE and bronze bush arrangement.
The stem arrangement connects the operating mechanism with the stainless-steel disc while maintaining the specified wafer-type construction.
Lining Options
The valve uses integrally moulded rubber lining to provide seating to the disc and contribute to sealing around 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 operating medium, chemical compatibility, pressure and temperature conditions.
Pressure and Temperature Rating
The valve is rated PN 2.5 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. Actual operating conditions should remain within the applicable product specifications.
Flange Compatibility
The wafer configuration is designed for sandwich installation between compatible flanges. 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.
Customers should verify flange dimensions, pressure class and bolt arrangement before installation.
Suitable Media
The specified valve configuration is suitable for applicable systems handling steam, water, oil, air and gases.
- Steam
- Water
- Oil
- Air
- Gases
Final material and lining selection should always be based on the actual operating medium and service conditions.
