Model 2A-2A

Model 2A-2A CONTROLAIR Pneumatic Marine Control Valve
– Back by popular demand
The rugged and reliable 2A-2A valve is now back in production. Captains prefer the 2A-2A Controlair as the clear choice among controls because of its purpose built design. The “Z” slot cover to guide the handle travel and the ability to lock the handle in position are the main reasons the 2A-2A continues to be a favorite. The valve allows single handle movement for direction and speed. The polished chrome-plated 303 stainless steel cover and the polished chrome-plated handle make for an attractive valve on a bridge console. The handle locks in any position simply by twisting the handle. The 2A-2A valve is completely constructed of non-ferrous materials for long, hard service. The 2-A-2A is available in 7-61 psi and 28-71 psi pressure ranges.

Model THD-2-FM CONTROLAIR Pneumatic Marine Control Valve
THD-2-FM valves provide single handle control for propulsion direction and engine speed for two engines. This top of the line model is ruggedly built from non-ferrous materials and has an attractive chrome-plated brass cover with chrome handles. The completely enclosed cover and rugged construction make it ideal for exposed station installations. Fore or aft movement to either control handle from neutral to the clutch position delivers supply pressure into the appropriate ahead or astern control line to engage the clutch. Further movement increases the pressure signal delivered to the engine governor. The neutral and clutch positions are detented for positive position indication. An adjustable friction brake holds the handles in any selected position. The THD-2-FM accommodates up to ¾” console thickness. The THD-2-FM is available in 10-65 psi and 30-70 psi pressure ranges.

Model HD-2-FM CONTROLAIR Pneumatic Marine Control Valve

This middle of the line model is ruggedly built from non-ferrous materials and has an attractive chrome-plated bronze cover with a chrome handle. The completely enclosed cover and rugged construction make it ideal for exposed station installations.

Fore or aft movement of the control handle from neutral to the clutch position delivers supply pressure into the ahead or astern control line to engage the appropriate clutch. Further movement increases the pressure signal delivered to the engine governor. The neutral and clutch positions are detented for positive position indication. The HD-2-FM is designed with an L-shaped handle so that two units can be mounted side by side for operation with one hand. An adjustable friction brake holds the handle in any selected position. The HD-2-FM is available in 10-65 psi, 30-70 psi and 10-70 psi pressure ranges.

Model HD-2-FC CONTROLAIR Pneumatic Marine Control Valve
The HD-2-FC CONTROLAIR Valve is a handle operated pressure control and directional flow control valve. It contains two 3-way directional valves and a pressure regulating portion, which are arranged to furnish inlet air pressure to two directional clutch control lines and graduated pressure to one infinite positioning speed control line.

The selection between the two clutch control lines depends upon handle movement to either side of “Neutral” position. The pressure in the speed control line is proportional to the position of the handle in either quadrant.

The cover is die-cast aluminum with grey textured polyester paint, with stainless steel handle, hub and yoke. The angled handle, so designed that when mounted side by side they can be operated by one hand, is equipped with an adjustable friction brake that will hold the handle in any selected position. The HD-2-FC is available in 0-65 psi pressure ranges with either right hand or left hand handle position options.

Model HD-2-FX CONTROLAIR Pneumatic Marine Control Valve
The HD-2-FX valve provides simple and efficient single handle control for propulsion direction and engine speed. It is frequently used as an engine room control, or on smaller craft as a bridge control.

Lightweight and rugged, non-ferrous construction, HD-2-FX valves are made of anodized die-cast aluminum for economy. The lever remains in the position where released. Holding friction is adjustable. Functional operation is the same as HD-2-FM and HD-2-FC CONTROLAIR valves. The HD-2-FX is available in 0-65 psi, 0-100 psi, 0-125 psi, 0-150 psi and 30-70 psi pressure ranges. A chrome-plated cover model is available in 0-65 psi.

Model HC-2-FM CONTROLAIR Pneumatic Marine Control Valve
The HC-2-FM valve is designed for open deck marine service and is the same as the HC-2-FX CONTROLAIR valve, except it features longer handle travel, more accurate positioning and a polished chrome-plated bronze cover and handle.

The valve is a lever operated, pressure regulating, 4-way directional valve. It consists of two 3-way directional valves and a 3-way pressure regulating portion. The regulating portion furnishes inlet air to the directional valves. Each directional valve has its own outlet port.

Initial lever movement from “mid” position selects the outlet port to be activated. Further lever movement in the same direction controls the outlet pressure at that point. The opposite port remains connected to atmosphere. Lever remains in the position where released. Handle holding friction is adjustable.

Use these valves to control two clutches, a clutch and a brake, two single acting cylinders or a double acting cylinder...wherever you want to selectively control pressure in either of two separate air lines with one lever. The pressure range is 0-65 psi.

Model HC-2-FX CONTROLAIR Pneumatic Marine Control Valve
The H-2-FX valve is a lever operated, pressure regulation, 4-way directional valve made of anodized die-cast aluminum. It consists of two 3-way directional valves and a 3-way pressure regulating portion. The regulating portion furnishes inlet air to the directional valves. Each directional valve has its own out port.

Initial lever movement from “mid” position selects the out port to be activated. Further lever movement in the same direction controls the outlet pressure at that port. The opposite port remains connected to atmosphere. Lever remains in the position where released. Handle holding friction is adjustable.

Model H-2-FM CONTROLAIR Pneumatic Marine Control Valve
The H-2-FM valve is designed for open deck marine service and features handle travel of 78°, plus accurate pressure control and a polished chrome-plated bronze cover, handle and grip.

This valve controls engine governor operation permitting the engine to be run at advanced speed for warm-up and check-out without engaging the clutch. After engine warm-up, control is transferred to the bridge. The H-2-FM is available with right handed handle in 10-65 psi, 10-150 psi and 30-70 psi pressure ranges. It is available with left handed handle in 10-65 psi and 30-70 psi pressure ranges.

Model H-3 CONTROLAIR Pneumatic Marine Control Valve
The H-3 CONTROLAIR Valve is equipped with a roller for operation by a cam or a similar mechanical device. Graduated pressure which is directly proportional to the amount of downward movement of the roller lever is delivered from the OUT port. Total movement is approximately 5/16” (7.9 mm) with the initial 1/16” (1.6 mm) travel used to close the exhaust valve. The H-3 is available with 0-65 psi, 0-100 psi, 0-125 psi, 0-150 psi, 0-15 psi, 0-25 psi and 0-75 psi pressure ranges.

Model H-3-G CONTROLAIR Pneumatic Marine Control Valve
This design is similar to the H-3 CONTROLAIR except the spring housing area is sealed and a biasing control pressure can be introduced through the tapped lower housing port to the underside of the diaphragm. By varying this signal, the output of the H-3-G CONTROLAIR can be biased or adjusted in proportion. This bias signal must be lower than the output signal. The H-3-G valve is available with 0-30 psi and 0-65 psi pressure ranges.

Model SH-3 CONTROLAIR Pneumatic Marine Control Valve
The SH-3 CONTROLAIR Valve is a pressure graduating valve similar to the H-3 CONTROLAIR Valve, but with a larger, more sensitive diaphragm for minimum hysteresis and maximum sensitivity of pressure graduation for optimum control of positioning devices such as servo positioners and applications where very precise control is required. The hysteresis = ± ¾ psi. The SH-3 valve is available with 10-65 psi and 3-15 psi pressure ranges.

Model H-4 CONTROLAIR Pneumatic Marine Control Valve
The H-4 CONTROLAIR Valve is a knob operated, 3-way pressure regulating valve. Arranged for panel mounting, this valve gives fine, vernier type pressure control in one delivery line. The knob holds in all positions and has adjustable stops to limit maximum and minimum travel.

Clockwise rotation of the knob increases pressure in the standard models. Opposite knob action is available. The H-4 is available with 0-65 psi, 0-100 psi, 0-125 psi, 0-150 psi, 0-30 psi, 0-65 psi and 0-100 psi pressure ranges.

Model H-4-G CONTROLAIR Pneumatic Marine Control Valve
This design is similar to the H-4 CONTROLAIR except the spring housing area is sealed and a control signal can be introduced under the diaphragm through the tapped lower housing port.

The delivery pressure is then regulated by the applied control signal and can be biased by operation of the control knob to adjust the output pressure approximately 10 psi (0.7 bar). The main use of the H-4-G is to balance the RPMs between two or more engines.
