Butterfly Valve (Wafer Type), PN 1.6 with S.S 304 Disc – Gear Operated is a compact industrial flow-control solution for suitable pipeline systems. The wafer construction allows the valve to be installed between compatible flanges, while the gear-operated mechanism provides controlled manual operation.
The valve features an S.G. Iron body, S.S. 304 stainless-steel disc and two-piece stem construction. Its PN 1.6 configuration has a maximum working pressure of 1.6 MPa and maximum working temperature of 90°C. The design follows IS 13095 / BS EN 593 (BS 5155) requirements.
BOTTOM CONTENT
Product Overview
Butterfly Valve (Wafer Type), PN 1.6 with S.S 304 Disc – Gear Operated is designed for flow isolation and control in suitable industrial pipeline systems. Its wafer-type construction provides a compact installation arrangement between compatible pipe flanges.
The gear-operated mechanism provides controlled manual operation, making this configuration suitable for larger pipeline sizes where a geared operating arrangement can provide practical valve operation.
The valve uses an S.G. Iron body with a stainless-steel disc accurately guided between the two stems. The two-piece stem arrangement is supported by PTFE or bronze bushes, while the moulded rubber lining provides the seating interface for the disc and sealing around the stem and matching flange connection.

Gear Operated Design
The gear-operated arrangement provides controlled manual operation of the valve. It is particularly useful for larger pipeline sizes where direct manual operation may require greater operating effort.
The operating mechanism should be used according to the product configuration and operating requirements. Customers should confirm the required valve size and application before ordering.
Wafer Type Construction
The wafer design is intended for installation between compatible pipeline flanges. Its compact configuration can help reduce installation space compared with longer valve arrangements.
Before installation, the pipeline flange standard, nominal diameter, pressure rating, bolt arrangement and available space should be checked for compatibility.
S.S. 304 Disc
The stainless-steel disc is the main rotating flow-control component of the valve. The disc is accurately guided between the two stems to support controlled opening and closing of the pipeline flow.
The specified disc construction corresponds to stainless steel S.S. 304 / CF8. Where required, alternative disc material configurations may be available depending on the application and product requirement.
Body and Lining Construction
The valve body is manufactured in S.G. Iron. The body lining provides the seating surface for the disc and contributes to sealing around the stem and matching flange connection.
EPDM and Nitrile are specified lining options. Neoprene, Viton and Silicon lining configurations may also be available for suitable requirements.
Lining selection should be based on the actual operating medium, chemical compatibility, pressure and temperature conditions.
Pressure Rating and Testing
The valve is rated PN 1.6 with a maximum working pressure of 1.6 MPa. The specified hydrostatic shell test pressure is 2.4 MPa and the seat hydrostatic test pressure is 1.76 MPa.
The stated maximum working temperature is 90°C. Actual service conditions should remain within the applicable product specifications.
Available Sizes
This configuration is available in the following nominal sizes:
- 200 mm / 8 inch
- 250 mm / 10 inch
- 300 mm / 12 inch
The available dimensional data should be checked against the customer’s pipeline and flange arrangement before ordering.
