HD-2-FX CONTROLAIR<\/b>\u00ae <\/b>VALVE<\/b><\/span><\/p>\n

Description of Models<\/b><\/span>
\nThe HD-2 Type Controlair Valves <\/b>are handle operated <\/span>4-way, exhausted center, pressure control <\/span>valves. <\/span>The typical unit contains two directional control 3-way <\/span>side valves and a pressure graduating portion that is <\/span>arranged to increase, decrease or maintain air pressure <\/span>to a separate delivery line. In neutral position, <\/span>both 3-way side valves exhaust both delivery lines. A <\/span>movement of 10 degrees either side of center position <\/span>opens the appropriate side valve and directs <\/span>pressure to the indicated outlet port. Continued <\/span>movement past 10 degrees up to full travel, or 46 <\/span>degrees either side of neutral continues to actuate <\/span>the pressure graduating portion to deliver a graduated<\/span>
\npressure according to the valve of the control <\/span>spring.<\/span><\/p>\n

Models<\/b><\/span>
\nThere are six models with similar valve functions, but<\/span>
\ndifferent handle operating characteristics.<\/span>
\nHD-2-X Controlair Valve <\/b>-Handle is spring returned<\/span>
\nto neutral position from all positions in the handle<\/span>
\ntravel. Some special models exist. See notes on<\/span>
\nIdentity schedule on page 7.<\/span>
\nHD-2-LX Controlair Valve <\/b>– Handle is spring returned<\/span>
\nto neutral position from all positions except at<\/span>
\nthe maximum pressure setting on both sides of center.<\/span>
\nThe handle is held in both extreme positions by<\/span>
\na mechanical detent.<\/span>
\nHD-2-FX Controlair Valve <\/b>– Handle is equipped with<\/span>
\na friction brake that will hold the handle in any position<\/span>
\nselected in the handle travel.<\/span>
\nHD-2-XS Controlair Valve <\/b>– Handle detents in both<\/span>
\nmaximum pressure positions. The handle is spring<\/span>
\nreturned to neutral position from all other positions in<\/span>
\nthe handle travel. Graduated pressure to port (8) is<\/span>
\nonly delivered in one direction of the handle movement.<\/span>
\nHD-2-FXR Controlair Valve <\/b>– Handle function is<\/span>
\nsimilar to the HD-2-FX Valve. The difference is the<\/span>
\ntwo directional valves are supplied <\/i>instead of being<\/span>
\nexhausted <\/i>when the handle is in the neutral position,<\/span>
\nHD-2-LS Controlair Valve<\/b>– Handle holds in full travel,<\/span>
\nneutral and detent positions.<\/span><\/p>\n
