Description

1/4 & 3/8 Inch High Flow Brass Solenoid Valve – 2/2 Way NC – Sunwell EK08 & EK09


The Sunwell EK08 and EK09 are compact high-flow brass solenoid valves designed for reliable control of air, water, gases, vacuum and light oils. Their assisted-lift diaphragm design provides zero pressure operation while delivering significantly higher flow rates than conventional direct acting valves of similar port size.

Available in 1/4" and 3/8" BSP ports, the EK Series offers two flow configurations: Model A for higher pressure performance and Model B for increased flow capacity. The forged brass body and stainless steel internal components provide long service life, while optional FKM or EPDM seals extend media compatibility.

Supplied with IP65 continuous duty coils, the EK Series is suitable for industrial automation, OEM machinery, vacuum systems and general fluid control applications. An optional ATEX certified coil is available for hazardous area installations.
