Normal working pressureUp to 1.5 MPa

Practical Notes

Valves must be tested for both hot and cold water pressure to ensure internal mixing chambers do not cross-leak.

Verify that the electroplating (usually chromium) meets the requirements of IS 1068 for adequate durability in wet domestic environments.
