Wafer check valve - DN 15 - 200, PN 16 | BOA-RVK

This particular valve is of the wafer style, it is a non return valve, with the body shape assisting in centring the device. The three stainless steel pins included can plug guide this device. It can be shut-off using the check disk, which is spring loaded. There are variations of this model that have reduced noise capabilities. A model with a either an O-ring (DN 125-200), or a plastic check desk (DN 15-100)is offered to consumers. None of the styles listed here will require any type of maintenance and these valves are useful for heating systems and also industrial systems. Pressure Equipment Directive 97/23/EC in the Fluid Group 2 section states that this device is compatible with gases and liquids that are not of a hazardous type. These valves can also be utilized for hot water heating systems, even those with a high temperature. They can also be used on heat transfer systems. These valves are ill-suited for fluids in question, which would be likely to corrode or otherwise destroy the valve materials. All technical code limitations will be complied with as needed.
