What are the standard pressure ratings for these valves?

The standard covers two pressure designations: PN 1.0 (1.0 MPa) and PN 1.6 (1.6 MPa) as per Clause 3.1.

What is the body material specified for these valves?

The body, bonnet, and other key components must be made of forged brass, specifically Grade FLB conforming to IS 8737 (Table 1).

What is the hydraulic body test pressure for a PN 1.6 valve?

The valve body must be tested at 3.0 MPa for PN 1.6 rated valves, without any leakage (Table 5).

What are the available sizes for these valves?

The standard covers nominal sizes from 15 mm to 100 mm (Clause 3.2).

Practical Notes

Ensure valves carry the ISI Mark as a confirmation of quality and compliance with the standard, which is mandatory for this product.

Always verify the pressure rating (PN 1.0 or PN 1.6) is suitable for the intended application's maximum working pressure.

Check compatibility of end connections, which are typically screwed female ends as per IS 554, with the connecting pipes.
