VAG | HADE Flap Valve PTK-BS
- Flap valve with slanted disk to ensure discharge of the medium preferably below the water level. Attachment by slip-on sleeve. Easy mounting due to low weight and absolute corrosion resistance due to the PE-HD material. Opens even at low differential pressure due to the low-resistance disk bearing. Ideally suited for gravity lines and for use in pumping stations.
- Sealing system/standard: Resilient seated
- With tilting disk (10° inclination) for minimal pressure loss
- For gravity lines
- Discharge preferably under water
- Discharge from drainage system at minimal pressure loss
- Top corrosion resistance by use of non-corrosive materials
- Low weight

I took a gamble on this sweater, amazon clothing seems to sometimes be way different quality than what’s pictured but I was very happy when I received this sweater!

his sweater is a bulky, fairly heavy winter sweater that will be awesome for the office or casual wear. The fabric is very silky soft. It’s nice and snuggly! I can’t wait for it to get cool enough to wear it!
