Description

The DN80 wafer check valve (09104.6516.31) uses a disc closure to prevent reverse flow of non-hazardous bulk materials such as cement. It is rated for 1.6 MPa and must be mounted vertically between pipeline flanges.

Advantages

High strength and reliabilityA grade 20 steel body to GOST 1050-2013 is rated for 1.6 MPa and provides durability in demanding conditions
Low opening pressureOpens at a differential pressure of just 0.001 MPa, reducing pneumatic conveying energy consumption
Compact dimensionsWafer construction allows fast, easy fitting between pipeline flanges without additional mounts
Wear-resistant sealMetal-to-metal disc and seat contact provides long service life with abrasive bulk materials
Automatic operationFully automatic operation without external controls ensures system safety

Applications

Cement and flour tankers
Stationary bulk material conveying systems at production facilities and grain elevators
Feed tankers and other dry bulk tankers
