Line blind valves

Safe system pressure testing with PERSTA DPV

Line blind valves from PERSTA are the safe choice when it comes to performing system pressure testing in compliance with regulations. The forged-steel casing keeps the weight down while enabling high temperature gradients and cyclical loads with no noticeable wear.

The higher the pressure, the tighter the bonnet

For every line blind valve, we bring our own QA system into line with the customer’s requirements and the inspection and test plan (ITP) created specifically for the customer. In accordance with VGB directives, the pressure seal bonnet closure also ensures greater tightness as the pressure rises. The promise we make to our customers to always deliver trouble-free products has also led to our decision not to use any special tools in assembly.
