AO -- GENERAL INFORMATION

The Brand, 4-way directional control valve is designed to be durable and dependable. The manually shifted handle provides metered flow to either port. Port flow is directly proportional to the movement of the lever. The tank port must go directly back to tank.

SPOOL TYPE – The spool types offered are tandem center 4-way (T), open center 4-way (O), fine metering (M), tandem metering (TM), closed center 4-way (C), and tandem 3-way (T3). (See chart on next page and schematics on page #4 for information on spool types)

ACTUATORS – Standard enclosed lever handle (G) pressurizes the B port when the handle is pushed towards the valve body (vertical mount). Enclosed lever handle (C) is similar to (G) except horizontal mount. Lever handle (L) pressurizes the B port when the handle is pushed towards the valve body. Lever handle (J) pressurizes A port when the handle is pushed towards the valve body. Pilot operated (P) is used to shift the valve from a remote location. Rotary handle (H) is used to rotate spool in or out of valve body. No actuator (N) uses G type spool. No actuator (M) uses J type spool.

SPOOL ACTION – Three-position detent (D) holds the spool in neutral and both active positions. Friction detent (F1) applies friction to the spool so that the spool does not move when the handle is released either side of neutral, a detent groove clearly indicates neutral position. Spring center (S) returns the handle to neutral when the handle is released. Spring center detent (SD) springs back to neutral from one position and is mechanically detented in the other position (flow out port A in detent). Spring center friction detent (SF1) springs back to neutral from one direction and functions similar to standard F1 in other direction (flow out port B in friction detent). Spring offset (SO) spring holds spool in one active position (P to B in offset position and neutral). Spring offset (SO2) spring holds spool in one active position (P to B in offset position, neutral and P to A). Rotary friction detent (E) applies friction to the spool as it is rotated so that the spool does not rotate when the handle is released either side of neutral, a detent groove clearly indicates neutral position. Two-position detent (2D) P to B only. Two-position detent (D2) P to A only. Adjustable relief (R) set to 1500 psi (103 bar)at factory. Normally closed electric switch (WC) used with (S), (F1) and (D) options only. Normally open electric switch (WO) used with (S), (F1) and (D) options only.
