Ground Water Backflow Preventers Datasheets

Miniature Low Cracking Pressure Check Valve -- CKV
from Beswick Engineering Co., Inc.

The check valve permits free flow in one direction and no (checked) flow in the opposite direction. This valve is specified in many applications because of its very low cracking pressure (typically less than 0.5 psig), its excellent repeatability, and leak-tight operation. The unique design of the... [See More]

Flood-Guard™ - Vertical One way Flow Check Valve
from General Pipe Cleaners

Flood-Guard ™ operates like a check valve to seal off water back-up caused by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. Then the Flood-Guard ™ float rises to seal off the drain opening until the water recedes. A screwdriver and a couple... [See More]

Reduced Pressure Zone Assembly -- 994BLT
from Watts

Model 994BLT Portable Hydrant Meter Backflow Preventers prevent the reverse flow of polluted from entering into the potable water supply where flow is in one direction and the possibility of cross-connection exists, such as at a fire hydrant or other non-permanent installation. It consists of... [See More]

Tideflex Check Valves
from Red Valve Company, Inc.

A Revolutionary Design for Backflow Prevention. Tideflex Duckbill Check Valves have low headloss and achieve the tightest possible seal for backflow operations, particularly at low flow rates. The flexibility of the Tideflex Check Valve allows the valve to compress around trapped solids, providing a... [See More]
