Caution) Because the LVN series cannot be used as a stop valve the flow rate will not be "0" when the number of needle rotations is "0." For details, refer to p. 945 in the catalog, "Precautions."
Examples of special tool use when connecting tubing
1. Use special tools to connect tubing.
Body class | Torque (N⋅m) |
---|---|
2 | 1.5 to 2.0 |
3 | 3.0 to 3.5 |
4 | 7.5 to 9.0 |
2. Tighten the nut until it touches the end surface of the body, and then tighten it an additional 1/8 turn to ensure that the nut has reached the end surface. If the nut will not turn any further, then it means a sufficient tightening has occurred. Refer to the appropriate tightening torques for piping shown to the left.
