1/8 & 1/4 Inch Brass Normally Open Solenoid Valve – Direct Acting – Sunwell RB03 & RB06


The Sunwell RB03 and RB06 are compact, direct acting normally open brass solenoid valves designed for reliable control of air, water, gases, vacuum and light oils without requiring a minimum pressure differential.

Their inline flow-through coil and body design creates an exceptionally compact installation while providing fast switching speeds and dependable long-term operation. Available with 1/8" or 1/4" BSP ports and two orifice sizes, the RB series is an excellent choice where space is limited and rapid response is required.
Supplied with FKM seals as standard, the valves are also available with optional NBR or EPDM seals to suit a wide range of industrial media. An optional ATEX certified coil is available for hazardous area applications.
