The 1/4" Mini Ball Valve, identified by Manufacturer Part Number (MPN) CMV-25, is a compact and robust component from Midwest Control. It is specifically designed for applications requiring gauge isolation on hydraulic and high-pressure pump stations. This valve features a 1/4" MNPT (Male National Pipe Taper) inlet and a 1/4" FNPT (Female National Pipe Taper) outlet.


Constructed with a one-piece nickel-plated brass (C3600) body and a chrome-plated brass ball, the valve ensures durability and corrosion resistance. The sealing mechanism utilizes PTFE ball seats and Viton® O-rings , which provide reliable sealing and allow the valve to be operated in either direction due to double ball seats. The valve comes with a polycarbonate wedge handle for operation. The CMV-25 is rated for 450 PSI Cold Working Pressure (CWP) and 150 WSP (Working Steam Pressure). It is also suitable for vacuum service up to 29.9" Hg. The valve can withstand a broad temperature range from -4°F to 370°F, making it suitable for various industrial fluids and conditions. Additionally, it has a blow-out proof stem for added safety.


This mini ball valve is panel-mountable and operates as a full port valve, minimizing pressure drop and maximizing flow. It meets MSS SP-110 Standards and is manufactured in an ISO Registered Factory. The product is also RoHS Compliant.
