The applications, which are identified by the generic term of “process industry”, require the use of component parts that are designed and manufactured with specific materials, undergo special treatments and engineered solutions, featuring particular requirements. Metal Work has a vast range of products best suited to intercept and control the flow of fluids, such as water, steam, mineral oi and numerous chemicals. More specifically, the range includes solenoid valves (series EV-FLUID), stopper pneumatic valves (series PV-FLUID*) and ball or butterfly valves with a rotary actuator (series RV-FLUID*). Solenoid valves can be classified according to their function (2/2 NC, 2/2 NO, 3/2 NC and NO), type of operation (direct-acting, servo-assisted action or mixed action), the threading of ports, the size of the orifice, the material of the body (brass or stainless steel) and the gasket materials. Ball-acting valves can be classified according to their function (2- or 3-way), the threading of ports, the orifice, the actuator interface (to ISO 5211), the material of the body (brass or stainless steel) and the gasket materials. Butterfly valves, which can be the “Wafer” type for installation between pipes or the Lug type for installation at the end of the system, are generally made of painted cast iron and come with orifices in various diameters and gaskets in different materials. The main materials used for gaskets are NBR, FKM-FPM, EPDM and PTFE.
