Versatile Three - and Four-way pressure regulating valves or a combs nation of pressure regulating and non-regulating three-way valves.

The REXROTH Type "H" CONTROLAIR Valves are a family of pneumatic pressure regulating, directional valves. Hand, foot or mechanically operated, these valves control both pressure and flow of air. Some control these functions in one air circuit. Others selectively control these functions in two separate and independent air circuits or in branches of the same circuit. Still others control these functions either selectively or simultaneously in three separate and independent branches of an air circuit.

With each valve, the position of the operator-Sever, pedal, cam or knob-determines the air pressure delivered by the valve. Changing operator positions changes delivery pressure. Once the operator's position is set, a CONTROLAIR Valve maintains the delivery pressure for that position-automatically. It feeds more air into a circuit to compensate for leakage and operations which reduce pressure, it vents air from a circuit to compensate for operations and other conditions which would increase a circuit's pressure.

Hand Lever operated for one pressure regulated circuit and non-regulated circuits.

Pipe Connections
Port 1-OUT, full inlet pressure when lever is moved 10° clockwise from "Off" (facing lever side of valve).
Port 2-IN pressure.
Port 8-OUT, graduated pressure when lever is moved clockwise from "Off."

Models
HE-2-X CONTROLAIR Valve - The lever returns from the extreme position to the valve's "clutch" or "Off" position when the operating force is removed.
HE-2-FX CONTROLAIR Valve - Lever remains in the position where released. Holding friction is adjustable.
HE-2-LX CONTROLAIR Valve - The lever returns to the valve's "Neutral" or "Off" position when manually moved out of the latch position (extreme travel position).
