Soft Start Valve

The soft start valve is to prevent air surge when valve opens since a sudden change in pressure might have a negative effect to the process. This custom angle valve with a small orifice allows a soft pump down and vacuum system isolation, it functions as a small bypass valve to the main isolation valve. We also offer a large isolation valve with a small bypass valve integrated in one piece.
