The MV-13 Series is a manually operated needle valve that offers precise control of flow in corrosive liquid and gas distribution systems, including those used in ultra-high purity (UHP) semiconductor manufacturing and clean-area applications.

The MV-13 Series features a molded PFA body and stem for high cycle life and extreme resistance to corrosion. The PFA stem stop prevents removal of the stem from the body when in service, thus ensuring safe and reliable operation from vacuum to working pressures up to 100 psig. The valve’s PTFE ferrule creates a leak-tight seal between the stem and body, which allows the valve to be utilized in applications where cleanliness and minimal particle generation are critical. The non-wetted components (PFA, ETFE, PVDF) of the MV-13 Series are also highly durable and afford the needle valve with high strength and maintenance-free operation.

The MV-13 Series needle valve is available in straight through and angle configurations, along with several orifice sizes. Depending on customer requirements, the valve can be fitted with a variety of inlet and outlet port connection sizes and types, including Parflare and Pargrip tube fittings. Both Parflare and Pargrip fittings allow for ease of assembly, thus reducing installation time and ensuring a leak-tight seal for minimal downtime.
