The 344BEC, 346BEC, and 356BEC valves are available in a normally-open configuration. Unlike standard shutoff ball valves, which are normally closed, normally-open valves will be in the closed position when the signal line (white wire or DIN terminal 2) is energized (+12 VDC) and will be in the open position when the signal is de-energized.

Features

• Normally-open valves are wired in the identical manner to normally-closed BEC style valves and operated by a single-pole single-throw (SPST) switch.
• Refer to the standard DirectoValve shutoff valve pages for typical features and specificatons of a dump valve.
