1/8, 1/4, 3/8 & 1/2 Inch Brass High Pressure Direct Acting Solenoid Valve – Sunwell ZS
The Sunwell ZS Series is a premium range of high-pressure direct acting brass solenoid valves designed for reliable automatic control of liquids, gases and vacuum applications. Available with port sizes from 1/8 inch to 1/2 inch, the ZS Series combines true zero-pressure operation with working pressures up to 40 Bar, making it suitable for demanding industrial and OEM applications.
Manufactured from a forged brass body with stainless steel internal components, the ZS Series is available with six orifice sizes and a wide choice of sealing materials, allowing the valve to be configured for applications ranging from vacuum systems and compressed gases through to fuel, steam and high-temperature process duties.
Supplied with Class H IP65 continuous duty coils, the ZS Series is suitable for industrial automation, laboratories, process control, chemical handling and general engineering applications. An optional ATEX certified coil is available for hazardous area installations.
