Description

DN15 Coaxial Solenoid Valve – 0-64 Bar Direct Acting

RSG 27115 High Pressure Coaxial Solenoid Valve for Fluids, Gases & Vacuum

The RSG 27115 is a direct acting 2/2 way coaxial solenoid valve designed for reliable switching of liquids, gases, vacuum and high-pressure process media from 0 Bar pressure.

Unlike conventional pilot-operated solenoid valves, the pressure-balanced coaxial design operates without a minimum differential pressure and provides reliable performance from vacuum through to 64 Bar. Suitable for fluids up to 500 cSt viscosity and a wide range of compatible gases, the RSG 271 Series is ideal for demanding industrial applications requiring higher pressure capability, low wear and exceptional service life.

The DN15 orifice provides increased flow capacity compared with DN10 models whilst maintaining zero-pressure operation, high leak-tightness, flexible material options and reliable performance across a wide range of industrial applications.
