nonreturn valve for boiler feedpump

How to Remove a Non-Return Valve on a Boiler

The non-return valve, also called a stop check valve, is usually positioned on a pipe between the boiler and the feed pump.Through this valve, hot water vapor from the boiler can be stopped or started. It consists of a disc and a stem, and it can be closed by turning down the stem and shutting off the flow.

In any case, a control valve for feedwater regulation to the boiler takes the fluid from the pump outlet and regulates the outlet flow rate to the boiler demand. The service of this valve is similar to the DEA level control valve, except at a significantly higher pressure. The fluid is taken from the DEA into the boiler feedpump and the

The only other option is a Universal twin pump pumping into the valve. You can not use a Universal single pump as the Universal pumps need to build up pressure against a closed valve to shut down. Back to top. We have a Universal (negative) head twin pump and the flow rate is too great. Is there any way to reduce the pressure or limit the flow?
