![]() Type 310 NACE Filter Regulator This unit incorporates all of the operating features of the Type 300 lter regulator, but is constructed of materials that meet NACE specication MR-01-75 for sulde stress cracking. H-2-LX CONTROLAIR Valve - Lever returns to minimum pressure position when released from any position except maximum pressure position. The Type 300 is a quality unit that is ideal as an economical alternative for control of process applications. H-2-FX CONTROLAIR Valve - Lever remains in the position where released. H-2-X CONTROLAIR Valve - Lever returns to minimum pressure position when released. OUT Port-Delivers graduated pressure in direct proportion to clockwise lever travel from minimum pressure position (facing lever side of valve). The following list of H-2 CONTROLAIR® valve piece numbers is provided for use in those cases where a handle location or a push/pull handle action is required by special control panel configurations. 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. Once the operator's position is set, a CONTROLAIR Valve maintains the delivery pressure for that position-automatically. Changing operator positions changes delivery pressure. ![]() With each valve, the position of the operator-Sever, pedal, cam or knob-determines the air pressure delivered by the valve. Still others control these functions either selectively or simultaneously in three separate and independent branches of an air circuit. Others selectively control these functions in two separate and independent air circuits or in branches of the same circuit. Some control these functions in one air circuit. ![]() Hand, foot or mechanically operated, these valves control both pressure and flow of air. The REXROTH Type "H" CONTROLAIR Valves are a family of pneumatic pressure regulating, directional valves. Versatile Three - and Four-way pressure regulating valves or a combination of pressure regulating and non-regulating three-way valves.
