1. Before assembling, all parts should be clean, without oil or grease, all burrsand sharp edges should be removed.
2. Nominal Pressure:1.6MPa;
Working Medium:water;
Working Temperature:t≤120°C
3.Glue is approval to NSF 61
4. Inspecting and testing conform to BS EN 12266-1:2003
1).Shell test:
Covering the entrance and exit of the valve, pressing the gland tightly to make the disc be in intermediate positions.
Full filling with liquid in the shell body to reach testing pressure 2.4MPa gradually.
Inspecting for the shell including the gland and union between the body and cap to see if there is leakage when
reaches to stipulated time 15s.
2).Seal function test:
Covering the two ends of the valve to make the disc be slight opening position and to reach to testing pressure
with 0.6±0.1MPa gas in the shell body. Releasing the pressure of one end when closing.After 15 s,no leakage.
5. Parallel pipe thread conform to ISO 228 (equivalent to DIN 259 and BS2779)
