H Controlair Valves

“H” Controlair® valves are a family of pneumatic pressure regulating, directional valves. They are versatile three- and four-way pressure regulating valves or a combination of pressure regulating and non-regulating three-way 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. The H Controlair® pressure control valves are extremely popular on oil and gas drilling and service rigs.

Product Features:  The H-2, HC-2, HD-2 and HE-2 Controlair® Valves are available with any one of the following types of lever return or holding characteristics. These characteristics are indicated by the suffix added to the designation.

• X - Self returning. The lever return from the extreme position to the valve’s “Neutral” or “Off” position when the operating force is removed. 
• LX - Self returning with latch. The lever returns to the valve’s “Neutral” or “Off” position when manually moved out of the latch position (extreme travel position). 
• FX- Self holding. The lever stays in any position in which it is placed. The holding friction is adjustable.
