The MV-11 Series is a 1/2 inch PFA manual diaphragm valve that is designed for use in ultra-high purity (UHP) and aggressive gas and liquid handling systems, including semiconductor manufacturing operations. The valve is available in 3-way configurations and utilizes a molded PFA body with precision-machined sealing areas for superior leak integrity and chemical resistance. With a multi-position mounting base, the 3-way configuration allows for increased mounting flexibility and connector fitting reduction, making it advantageous in areas where workable space is limited.
The MV-11 Series PFA valve features a Fluoropolymer-coated stainless steel spring which reduces the effects of corrosive environments and ensures compatibility with a wide range of aggressive process media. The valve is also equipped with a one-piece machine modified PTFE diaphragm, which provides higher cycle life when compared to conventional PTFE. For increased flexibility, MV-11 Series valves can be fitted with a variety of port configurations, including Parflare and Pargrip tube fittings. The fittings reduce assembly time and installation costs, while ensuring a leak-tight seal for reliability in applications where cleanliness is critical.
The tongue and groove seal of the MV-11 Series valve ensures a positive diaphragm to body seal, resulting in high cycle life. Its full 1/2 inch orifice offers maximum flow capability in a compact package. Flow capacities vary depending on port size and configuration type (up to 3.7 Cv).
The MV-11 Series PFA valve is available with a submergible option, which isolates components from the external environment and allows the valve to remain functional while operating in wet or gaseous corrosive environments.
