Zwick – (SIL 3) Emergency Shutdown Valves (ESD)Enquire Now
Zwick Emergency Shutdown Valves (ESD) with Partial Stroke Testing (PST) solutions are designed to meet the requirements and standards of High Integrity Protection Systems (HIPPS). HIPPS is a type of safety instrumented system (SIS) designed to reduce the risk that can arise if the pressure of a system exceeds its design pressure.
A need for HIPPS valve solutions are typically found in industries such as Synthetic Fuels, Chemicals as well as Oil & Gas. Whether the application is in a chemical processing plant or a refinery, containing the loss due to over pressurisation is of critical importance. Heavy duty SIL 3 scotch yoke actuators with a closing time of <1 sec are readily available. Should pressures in a chemical process plant be exceeded, hazardous, explosive or toxic chemicals may be released into the atmosphere threatening lives and endangering process plant and the environment.
