The pipe and thread should be clean and please note the following points.
1. The direct-acting valves can be installed with any position. Unless the air is clean, we suggest keeping coil upwards for avoiding fluid or debris in plunger tube that could lead to side effects.
2. The diaphragm valves should be installed with coil upwards. Otherwise the valve would be unstable.
