Opening and closing differential pressure (difference between ON and OFF) is 1/2 of SPS-8T . In addition, SPS-8TF1 is available
when a small opening and closing pressure difference is required . In addition to the screw-in type, VCR fittings and ferrule fittings are also available for mounting the pressure-applying part (wetted part). There are pressure resistances of 0.5, 2.0, and 3.0 MPa (5, 20, and 30 kg/cm²) according to the purpose of use.
As a general rule, the pressure setting is the factory setting. When ordering, please specify the operating pressure value (ON, OFF) and port size .
