SIL certified valves

There is only a small, exclusive circle of companies that may claim SIL certification of their process valves in use in power plants. “In Germany, only three companies may carry this quality certificate – Buschjost is among them,” reports Stefan Gotal, Key Account Manager for conventional and nuclear energy at the Bad Oeynhausen company.

Even at Buschjost, which has been engaged in power plant technology for three decades, the SIL certification is not taken for granted. It is not only a financial challenge, but also an organizational and technical challenge to have products certified according to SIL (Safety Integrity Level). “We have undertaken this endeavour quite deliberately to make it clear that our goal is a considerable expansion of our share of the rapidly growing market in the worldwide power generation sector,” says Stefan Gotal, with an eye to the future.

SIL certification refers to applications in which electrical, electronic, or programmable electronic systems are installed to perform safety functions. “Therefore in situations where there can be no failures, SIL certification provides the required dependability,” says Stefan Gotal. Three selected series of piston valves in the nominal sizes of DN 15 to DN 100 and in connection sizes of ½” to 2”, suitable for liquid as well as gas media, are currently certified SIL2.

Buschjost process valves, in combination with a fully developed accessories programme, offer safety and reliability to power plant operators. “And that,” says Stefan Gotal, “is of central importance to a key industry of the future that is very much in the public eye.”
