2 Walz & Krenzer, Inc. 2 W alz & Krenzer, Inc. (WK) is a wholly U.S. owned small business specializing in the design and supply of custom fabricated watertight and airtight doors, flood barriers, and hatches. Since 1939, the company has offered a wide range of competitively priced manual and power operated doors, flood barriers, and hatches designed to seal any size opening against water, chemical, air, and blast pressure. WK offers unparalleled experience in the design of custom watertight closures, from the most simple flood barriers to complex power operated (hydraulic/ pneumatic) gates and doors. PRODUCT OVERVIEW All WK closures are custom designed and manufactured to your specifications. Closures can be designed to comply with FEMA, radioactive, blast, or other requirements. Watertight doors, hatches, and flood barriers are supplied for any size opening, and can be designed to withstand almost any pressure requirements. All closures can be operated either manually or with hydraulic or pneumatic controls. Compression, lip seal, or inflatable gaskets in the closure s panel are secured against the closure frame by securing devices to provide an effective watertight or airtight seal. Installation is achieved by either bolting or welding the frame to an existing structure or by embedding an integral masonry frame in newly poured concrete. All closures are available in steel, aluminum, or stainless steel. Prior to release for manufacturing, all WK drawings are approved by in-house licensed Professional Engineers.

Lower costs Lip seal flood barriers are available in hinged or removable configurations. Openings wider than 10 often require multiple panels with removable braces.

These flood barriers offer a fully watertight seal and are recommended for most applications. The radiused corners are small enough so as not to present a tripping hazard.

There are no gaskets to inflate or bolts to tighten. Increased reliability; there is no inflatable gasket that could lose air pressure. Minimal frame construction offers improved aesthetics. Lower costs Lip seal flood barriers are available in hinged or removable configurations. Openings wider than 10 often require multiple panels with removable braces. Large panels may be supplied with mounted rollers for ease in transportation and installation. Single panel lip seal flood barriers have a very small (2") corner radius. These flood barriers offer a fully watertight seal and are recommended for most applications. The radiused corners are small enough so as not to present a tripping hazard. In cases where the small corner radius creates interference problems or at a junction of panels in multi-panel floodgates, square corners can be utilized. Very slight leakage may occur at the square gasket corners, but this leakage rate is significantly less than the FEMA allowable leakage rates. When the weight of the removable panel is a concern, we offer an aluminum composite panel material. Use of this aluminum skinned composite material reduces the panel weight by about 45%.
