Coaxial solenoid valve 2/2 0-20 Bar Brass 1/2-11/4 DN20

Description

DN20 Coaxial Solenoid Valve – 0-20 Bar Direct Acting

RSG 26920 Brass Coaxial Solenoid Valve for High Viscosity Fluids up to 1000 cSt

The RSG 26920 is a direct acting 2/2 way coaxial solenoid valve designed for reliable switching of liquids, oils, chemicals and industrial process fluids from 0 Bar pressure.

Unlike conventional pilot-operated solenoid valves, the pressure-balanced coaxial design requires no minimum differential pressure and is suitable for fluids up to 1000 cSt viscosity. This makes the valve particularly suitable for demanding industrial applications involving lubricants, viscous media and process fluids where reliable operation is critical.

The larger DN20 orifice provides significantly increased flow capacity whilst maintaining the advantages of true zero-pressure operation, low wear, high reliability and long service life.
