Griffco achieves PED certification for pressure relief, safety, back pressure valves

New York-based manufacturer Griffco Valve has earned certification for CE under the Pressure Equipment Directive (PED) 97/23/EC Category 4, Modules B and D for its design and manufacture of pressure relief/safety valves and back pressure valves.

Griffco is one of the first diaphragm pressure relief valves certified to this level of CE marking. The company says that this will allow customers to save money when buying pressure relief, back pressure, or safety valves as well as offer superior sealing technology with the inherent diaphragm interface.

Griffco's diaphragm valve design limits the number of wetted parts to just two, the valve body and the PTFE-faced diaphragm. With various wetted materials available (plastics, composites, alloys, etc.), Griffco's products are able to fit a range of complex and demanding customer applications.
