344B and 346B Regulating Ball Valves

September 3rd, 2009

344B&346B Regulating Ball
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, 2009

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.

Diaphragm-Type Pressure Relief/Regulating Valves

September 3rd, 2009

diaphraim Pressure Relief
Model 8460

Features

  • Flow rate to 56 gpm (212 l/min) for 1/2″ and 70 gpm (265 l/min) for 3/4″.
  • Stainless steel springs, responsive to the pressure range of each vavle.
  • Extra large valve passages to handle full flow from supply line.
  • Positive locknut to hold adjustment screw firmly in place. Not affected by jarring and vibration.

Piston-Type Pressure Relief/Regulating Valves

September 2nd, 2009

Piston
Bypasses excess liquid. Adjustable to maintain control of line pressure at any pressure within the valve’s operating range. Selected pressure setting firmly held in place by locknut. Extra large valve passages to handle large flows.

Model 23120 and Model 23120A

Features

  • Model 23120 has a 302 stainless steel spring and EPDM O-ring.
  • Model 23120A has a 316 stainless steel spring and Viton® O-ring.
  • Excellent chemical resistance.
  • 1/4″ port for pressure gauge pipe plug included.

AA144A-1-3 DirectoValve® Control Valves

September 2nd, 2009

144A-1-3
The three-way solenoid-operated DirectoValve control valve bypasses boom flow to maintain constant spraying pressure when one or more boom sections are shut off. To maintain pressure with a 23520 throttling valve, outlet 2 must be throttled to match the total capacity of the nozzles on that boom section.
Features

  • For pressures up to 65 psi (4.5 bar).
  • 8 gpm (30 l/min) with a 5 psi (0.34 bar) pressure drop.
  • 2.5 amp current draw.
  • Encapsulated 12 VDC coil can be easily changed without removing valve from line.
  • Polypropylene body for chemical resistance.
  • Internal metal parts are stainless steel.
  • Chemical resistant EPDM diaphragms and seat washers.

Note: 23520 throttling valve not included.

AA144P-1-3 DirectoValve® Control Valves

September 2nd, 2009

AA144P-1-3
The 144P-1-3 three-way solenoid-operated DirectoValve control valve was specifically designed to provide bypass control in spraying applications. When used with part number 23520-PP throttling valve or a 4916 metering orifice place in the bypass line, it can provide for a constant pressure spray system.
Features

  • For pressures up to 65 psi (4.5 bar).
  • 8 gpm (30 l/min) with a 5 psi (0.34 bar) pressure drop.
  • Fabric reinforced Viton® diaphragms.
  • Nylon encapsulated 12 VDC coil with 1/4″ QuickConnect terminals.
  • Power requirement 2.5 amp.
  • Glass filled polypropylene (black) valve body.
  • Internal metal parts are stainless steel.
  • No stroke adjustment needed.
  • Corrosion resistant, 430SS solenoid grade armature and armature stop.

Note: 23520 throttling valve not included..
