Product DescriptionDescription of ModelsThe HD-2 Type Controlair Valves are handle operated 4-way, exhausted center, pressure controlvalves.The typical unit contains two directional control 3-way side valves and a pressure graduating portion that is arranged to increase, decrease or maintain air pressure to a separate delivery line. In neutral position, both 3-way side valves exhaust both delivery lines. A movement of 10 degrees either side of center position opens the appropriate side valve and directs pressure to the indicated outlet port. Continued movement past 10 degrees up to full travel, or 46 degrees either side of neutral continues to actuate the pressure graduating portion to deliver a graduated pressure according to the valve of the control spring.Models: There are six models with similar valve functions, but different handle operating characteristics.HD-2-X Controlair Valve -Handle is spring returnedto neutral position from all positions in the handletravel. Some special models exist. See notes onIdentity schedule on page 7.HD-2-LX Controlair Valve - Handle is spring returnedto neutral position from all positions except atthe maximum pressure setting on both sides of center.The handle is held in both extreme positions by a mechanical detent.HD-2-FX Controlair Valve - Handle is equipped witha friction brake that will hold the handle in any positionselected in the handle travel.HD-2-XS Controlair Valve- Handle detents in bothmaximum pressure positions. The handle is springreturned to neutral position from all other positions inthe handle travel. Graduated pressure to port (8) isonly delivered in one direction of the handle movement.HD-2-FXR Controlair Valve - Handle function issimilar to the HD-2-FX Valve. The difference is thetwo directional valves are supplied instead of beingexhausted when the handle is in the neutral position,HD-2-LS Controlair Valve- Handle holds in full travel,neutral and detent positions.H-2-X/P50493-3 R431002640H-2-LX/P50499-3 R431002654H-4/P50967-1 R431002818H-4/P50967-2 R431002819H-4 /P50967-3 R431002820HD-2-FX/P50970-1 R431002823/ IA295HD-2-FX/P50970-3 R431002825/ IA295HD-2-X/P50973-1/ R431002831/ IA295HD-2-X/P50973-3 R431002833 /IA295HC-2-X/P50975-3 R431002837HE-2-FX/P51612 -1 R431002912/ IA285HE-2-FX/P51612-3 R431002914 / IA285P52935-4 R431003040H-1-A/P52971-1 R4310030632-BA-1/P54692-2/ R431003427 /IA1982-BA-1/P54692-4 R431003429/ IA1984-S/P55161 R4310036646-S/P55162 R431003665
