Description

1/8"–1/4" Brass 3/2 Way Solenoid Valve 0–8 Bar Normally Closed


The Sunwell BT04 and BT06 Series are compact direct acting 3/2 way normally closed brass solenoid valves designed for controlling air, water, vacuum, gases, light oils and other low viscosity fluids. Available with 1/8" or 1/4" BSP threaded ports, these valves provide reliable switching with no minimum operating pressure, making them ideal for vacuum, pneumatic and process control applications.

Manufactured with a forged brass body and stainless steel internal components, the BT Series is available with NBR, EPDM, FKM or FFKM (Kalrez®) seals and a choice of compact 6 Watt or larger 6.8 Watt Nass Magnet coils. Optional ATEX Ex m coils are available for hazardous area installations.
