How to read the marking on our valves
- PARAKH
- Our name. Every valve we make carries it.
- 50 or 2
- Nominal size: millimetres on bronze valves (IS 778), inches on cast steel (API).
- CL 1 · CL 2
- IS 778 pressure class: Class 1 for up to 1.0 MPa, Class 2 for up to 1.6 MPa (water at 45 °C).
- 150 · 300
- ASME pressure class on cast-steel valves.
- LTB 2 · WCB · CF8M
- Body material: leaded tin bronze to IS 318; cast carbon steel to ASTM A216; cast stainless to ASTM A351.
- Flow arrow
- Direction of flow, on globe and check valves and strainers. Fit it with the arrow.
- IS 778
- Made under our BIS licence for IS 778 (bronze valves only).
- 26 04 · HT 26-0417
- Batch (year and month) on bronze valves; heat number on cast steel. Give it to us and we find the valve's test record.
Made to your drawing
About a third of what we make is to customers' own drawings: special face-to-face lengths, flange drillings, trims and markings. Send the drawing with the quantity and we'll quote with the pattern cost shown separately.
