The solenoid valves of the K09434 series are 2/2 way, they are normally closed with direct drive with female gas threaded connections.
The valve body is made from a single piece of AISI 303 stainless steel bar, currently on the market there are only brass versions.
The sleeve is also made of stainless steel obtained from a solid bar and the tightness between the fixed core and the sleeve is guaranteed by the presence of an O. Ring in HNBR, a compound compatible with almost all oils and with many of the refrigerant gas mixtures that it can work at operating temperatures between -40 ° C and 150 ° C. All the coils mounted on the valves are of the 10000BH series, CE certified and with a power necessary to guarantee openings up to 150 bar.
The coils have insulation class H and have a winding made with enameled copper wire capable of withstanding up to 180 ° C. The external casing is made with dielectric and waterproof resins that guarantee effective insulation. To have greater sealing guarantees, a PTFE gasket (Olab standard) has been inserted between the sleeve and the valve body. This seal is absent in most other products on the market.
