Pit valve (with filter) "PA type"
Prevent the infiltration of groundwater and sediment! Synthetic resin pit valve.
The pit valve (with filter) "PA type" allows infiltrated water from pits (such as handholes for information boxes or joint trenches) buried underground to permeate into the ground, preventing the intrusion of groundwater and soil. The length of the main body can be adjusted to match the thickness of the pit wall. The socket part of the main body has ribs, which enhances its compatibility with concrete and its watertightness. 【Features】 - Prevents backflow into the pit even when the groundwater level is high - Prevents the intrusion of soil and other materials by using a filter - Can be capped with the included watertight cap (only for PA-75) - Can be retrofitted and is compatible with both new and existing installations For more details, please contact us or download the catalog.
