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.

The H-1-A CONTROLAIR Valve is a pedal actuated 3-way pressure regulating valve that is designed for installations in which its operator is standing or in which part of the valve cannot extend below floor level. Depressing its pedal increases the outlet pressure. Raising the pedal decreases the outlet pressure. The pedal is self-returning.

This valve is suitable for industrial control and any use where foot operated pressure control is desired.
