Parts of the bidirectional and unidirectional valve group, these controls have a needle-type construction. The body is made of aluminum and the needle is brass. Threaded ports include G?, G3/8, G? and G1/8. Nominal pressure is 6bar and operating pressure is 1?10bar for G1/8-G? models and 2?10bar for G3/8 ? G? models.
As for the nominal diameter, M5=1,5-G1/8 = 2 or 3mm ? G? =4 or 6mm ? G3/8 and G? = 7mm. The operating temperature range is 0-80 degrees Celsius (with dry air ?20 degrees Celsius).
