2/2 normally closed fluid valves with direct-acting 030/050 and internally piloted 150/200/250 structures. Match the pressure differential, passage, voltage and connection; send the model or label, quantity and destination for a quotation.
No. 030 is a size series. X/H/blank/L/T change its orifice from 1.5 to 6 mm and its maximum pressure differential from 3.0 to 0.1 MPa. Send the complete prefix and coil fields.
Compare the installed code, medium, inlet/outlet pressures and envelope. The pilot 150/200/250 structure needs a positive minimum pressure differential; both structures are normally closed. Labels or photos can start an inquiry.
