Introducing the 4-Inch Aluminum Blast Gate by POWERTEC. This must-have dust collector attachment helps maximize your dust collector system by regulating proper air flow to your designated machine of choice. Open and closed, it acts as an in-line gate to control the vacuum flow to specified areas of your work shop. Additionally, this aluminum blast gate works seamlessly with properly sized plastic and metal ducts, flexible hoses and 4-inch ports for an assortment of popular brands. Self-Cleaning Unlike other models that require constant attention, this unit possesses a self-cleaning gate (open slot) at the back that allows for clog-free operation. It also possesses a built-in stop that keeps the gate exactly where you need it during operation. When properly used, this self cleaning blast gate not only helps eliminate constant maintenance from jamming, but prevents air leakage that would otherwise disrupt your workflow.

We are committed to exceeding expectations, while bringing the latest innovations, technology, and product development to the industry.

This type of slide gate valve was originally designed for draining tanks and controlling shallow bodies of water like ponds and lagoons. They can also be used as shut off valves in low pressure or vacuum air lines. Please note that each valve size has an open and closed pressure rating. Because the plastic paddle can flex with flowing water they are not good for throttling water or trying to close the valve with fast moving water – thus the low mid flow cut off water pressure of approximately 6 pounds per square inch (psi). These slide valves are sometimes referred to as “knife or guillotine” gate valves and are a great alternative to ball valves in low pressure applications since they are full flow, quick opening, and are generally a much lower cost especially in larger sizes. They work well with soft debris like waste but small hard debris can settle in the bottom of the valve seat/slot and prevent it from closing completely. They can easily be cleaned or repaired by unbolting and replacing the seals or valve body. The handles simply unscrew for easy replacement – if you do so be sure not to damage the valve shaft. Extension rods are available for remote actuation. The Valterra 7101 gate valve has 1-1/2″ Schedule 40 female slip fittings which receive 1-1/2″ pipe. Black acrylonitrile butadiene styrene (ABS) body and hub fittings are resistant to corrosion and mild chemicals as are the polypropolene (PP) paddle and thermoplastic vulcanizate (TPV) seals. The valve shaft is made of 304 stainless steel. Hardware is zinc plated steel. It has a maximum pressure rating of 45 psi in the closed position, 30 psi in the open position, and a mid-flow maximum closing pressure rating of 6 psi. The maximum temperature rating is 205 degrees F (96 degrees C). See Gate Valve Measurement chart for dimensions and Head Pressure chart for determining the pressure based on the height of water being held back.

Unrestricted flow, simple push/pull operation, ideal for quick shut-off.

From the Manufacturer

Used in every dust collection system to control air flow from one machine to another, blast gates maximize system efficiency. We offer blast gates in both black ABS plastic and aluminum.

This slide gate valve has low pressure & vacuum applications for hog/poultry sheds, slurry ponds, aquaculture, flood irrigation/secondary containment and overflow, waste water control, fish hatcheries/transport, cooling towers as well as many general purpose applications. Please note that this valve design has an open and closed pressure rating. Because the stainless steel paddle can flex with flowing water it is not good for throttling water or trying to close the valve with fast moving water – thus the low mid-flow cut off water pressure of 2.5 pounds per square inch (psi). These slide valves are sometimes referred to as “knife or guillotine” gate valves and are great in low pressure applications since they are full flow, quick opening, and are generally a much lower cost than high pressure rated valves. They work well with soft debris like waste but small hard debris can settle in the bottom of the valve seat/slot and prevent it from closing completely. They can easily be repaired by unbolting and replacing the gate seals or valve body and the handle can also be replaced. The Valterra 6801 gate valve has 8″ slip/hub fittings which receive 8″ PVC pipe. The white Poly Vinyl Chloride (PVC) body and hub fittings are resistant to corrosion and mild chemicals as are the thermoplastic vulcanizate (TPV) seals. Its shaft, handle, paddle and hardware are made of 304 stainless steel. It has a maximum pressure rating in the open position of 6 psi and 10 psi in the closed position, a mid-flow cut off maximum pressure rating of 2.5 psi, and a maximum temperature rating of 167 degrees F (75 degrees C). See Gate Valve Measurement chart for dimensions and Head Pressure chart for determining the pressure based on the height of water being held back.
