Hauck valves are a dependable and accurate means of controlling the flow or air or gas to burners on furnaces, ovens, kilns, dryers and for other industrial control applications. Hauck rectangular port valves feature an easy, single adjustment and are designed to hold the desired setting in either automatic or manual operation systems.
• Single adjustment-positive locking
• Adjustable limit stops
• May be installed in any position
• Mounting pads for control motor/other
valves
• Low torque
Valve flow rate is controlled by operating the lever to rotate the cylindrical piston for desired amount of port opening. When necessary for conditions of application, the height of the rectangular port opening can be adjusted for the entire range of lever travel, by merely turning a single knurled knob. This knob has “close” and “open” direction arrows, and a socket screw for positive locking of position.
Full control range of the valve is obtained by 90 degrees rotation of lever. The adjustable radius and positioning features of the lever permit easy linkage to a control motor or drive mechanism. A ball joint snap connection on the lever eliminates friction from misalignment and allows the valve to be instantly disconnected from a control system, for manual operation or readjustment. Adjustable limit stop screws for the valve pointer are vibration-proof.
A separate locking screw, friction type and vibration-proof, is provided to lock any manual setting of valve pointer. Valve piston shaft has a ball thrust bearing and take-up screw which eliminates cylinder end play and related flow variations.
Designed for efficient controlling, these units are not intended to be used as a shut-off valve.
Hauck Adjustable Port Valves have mounting pads drilled and tapped on both sides. They can be provided with connecting linkage and brackets for automatic control, and in multiple valve units. Units combining other Hauck valves are also available.
Entire valve internals with valve cover assembly are removable from valve body by unscrewing the cover plate screws.
All valve bodies through 4 inch size are cast iron. Larger sizes are of steel. Valve pistons are of machined aluminum alloy in all sizes. Valve covers are aluminum alloy in sizes 1 inch through 4 inch, and steel in the 6, 8, and 10 inch sizes.
Valve sizes 1 inch through 2 inch have one- piece bodies with screwed connections. Valves sizes 3 inch and 4 inch have flanged type screw connections. The 6, 8, and 10 inch valves are flanged for 125 lb. American Standard Flange size.
Valve sizes 1 inch through 4 inch are designed for operating pressures up to 15 psig. The 6, 8, and 10 inch valves are rated for pressures up to 5 psig. PVS valves may be used with temperatures up to 300° F.
Manual or automatic control is by moving the Adjustable Radius Control Lever. The piston is thereby rotated to proportionally uncover the rectangular port in the valve body. The height of the port is adjusted by a single adjusting knob. When the height adjustment is made to satisfy maximum flow conditions, this establishes the port height for all rotational valve positions.
