## Overview

The Valterra 4" PVC Gate Valve features a robust 304 stainless steel shaft and paddle combined with corrosion-resistant Schedule 40 PVC fittings. Designed for low-pressure and vacuum applications up to 15 psi, it offers full port flow and quick push/pull operation. Its bolted assembly and removable aluminum handle simplify maintenance, making it ideal for aquaculture, slurry ponds, and sewer line shut-off with reliable leak-proof performance.

## Description

This slide gate valve has low pressure & vacuum applications in climatically controlled warehouses, hog/poultry sheds, slurry ponds, aquaculture/koi ponds, and sewer line shut off and waste water control as well as many general applications. Please note that each valve size has an open and closed pressure rating. Because the stainless steel 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 7 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. 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. The metal handle simply unscrews for easy replacement – if you do so be sure not to damage the valve shaft. The Valterra 6401 gate valve has 4" Schedule 40 female slip/hub fittings which receive 4" 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 and paddle are made of 304 stainless steel and the handle is aluminum. Hardware is zinc plated steel. It has a maximum pressure rating in the open position of 15 psi and 15 psi in the closed position, a mid-flow cut off maximum pressure rating of 7 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.

Review: High quality! - Very substantial piece, very well made and heavy duty.
Review: Worked as described - This worked perfectly for an install for a waste water grinder and still be able to use a conventional septic system as needed. We weren't sure where else that we could purchase these in our small town. They were also a better price on desertcart than other plumbing places.

## Questions & Answers

**Q: Is this NSF 61 approved for drinking water?**
A: The valve itself does not have a NSF 61 certified.

**Q: Would this work with thin walled pvc for sewer? specifically d2729 pvc pipe for drain applications?**
A: The Valterra 4" 6401 valve is made for Schedule 40 pvc pipe.

**Q: I need two monday anyway to get them shipped asap?**
A: We would be unable to ship until Monday

**Q: Can the shaft be extended?  I see valterra has a extension handle for gate valves, which one will work on the 6401 knife gate valve?**
A: Yes, we do have extension rods for the 4" valve. The part numbers depend on the length you are looking for.
For example we have the X4-12, which is a 12" extension rod for the 6401 valve. We also have an X4-24, X4-36, X4-48.

### ⭐⭐⭐⭐⭐ Good product but beware
*by R***. on March 13, 2024*

Buy these only on Amazon for a secure transaction. There is a scammer called Lamouren which offers these at a ridiculously low price, takes your money and then never delivers or responds. Be careful and buy Amazon merchants.
