Stop check valves

The use of a Y-type globe stop check valve is well known to replace a separate stop and check valve. However our new PERSTA DRA stop check valve will be the new standard as this type combines the advantages of a combined configuration with a much lower pressure drop and a non-sticking trim. In main steam line applications, the DRA stop check valve will even contribute to an increase in revenue.

 
New developments within PERSTA have combined the tapered parallel slide gate valve, with a full swing check valve, brought together in one valve body. Based on a standard gate valve body and standard stock items a stop-check valve can be created. With a swing check valve and the straight through pattern of the valve body the pressure drop is negligible. The very low pressure drop in main steam line applications will result in an additional 2-3bar available steam pressure at the turbine inlet.
