Electric Regulating Valves
October 22nd, 2009344B and 346B Regulating Ball Valves
September 3rd, 2009
The 340 series electrical regulating valves are designed to produce linear flow regulation and shutoff control in agricultural applications. Both models are available in several styles and motor speeds to accommodate different types of applications.
Features
- Available in 2-way and 3-way versions.
- Available in 1, 3, or 6 rpm motor speeds. Note: The PR version cycle times is double that of an R or RL version.
- Two-wire lead provides easy installation with 12 VDC systems.
- Low power consumption, less than 1 amp.
- Offered in a variety of inlet/outlet connections.
- Wetted parts are nylon, polypropylene, stainless steel, Teflon®, and Viton®.M
Normally-Open (Bypass) Valves
September 3rd, 2009The 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.
