Safety Warning

Full Product Description

The MV-10 Series is a 1/4 inch manually operated PFA diaphragm valve that is designed for use in ultra-high purity (UHP) and aggressive gas and liquid handling systems, including those seen in semiconductor manufacturing and clean-area applications. 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.

The MV-10 Series is equipped with a one-piece modified PTFE diaphragm, which provides excellent flexibility and high cycle life for lower replacement costs and less downtime. It also features a Fluoropolymer-coated stainless steel spring, which reduces the effects of corrosive environments and enables compatibility with a wide range of process media. Depending on customer requirements, MV-10 Series valves can be fitted with a variety of port configurations, including Parflare and Pargrip tube fittings. The fittings reduce assembly and installation time, while ensuring a leak-tight seal for performance in applications where cleanliness is critical.

The MV-10 Series PFA valve’s exacting design controls seat and diaphragm stresses to provide a reliable and maintenance-free service life. Its tongue and groove seal ensures a positive diaphragm to body seal, resulting in minimal particle entrapment and isolation of process media. The valve features a full 1/4 inch orifice with no restrictions for maximum flow at working pressures up to 80 psig. Flow capacities range from 0.20 – 0.62 depending on port size and configuration.

The MV-10 is 1/4 turn operated and has a removable handle for tamper resistance, which eliminates the requirement for a separate lockout device.
