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 G½, G3/8, G¼ and G1/8. Nominal pressure is 6bar and operating pressure is 1÷10bar for G1/8-G¼ models and 2÷10bar for G3/8 – G½ models.
As for the nominal diameter, M5=1,5-G1/8 = 2 or 3mm – G¼ =4 or 6mm – G3/8 and G½ = 7mm. The operating temperature range is 0-80 degrees Celsius (with dry air –20 degrees Celsius).
