Mechanical Dump Valve

The CV45, now available with patent pending Gator Technology, is a low pressure, full port, mechanical dump valve. It features balanced plug control trim with a quick opening characteristic. The CV45’s full port allows for high flow rates and its soft seat design gives it a consistent leak free shut off.

The CV45 can be used for discharging liquid or gas from separators, treaters, knockouts or other vessels making it a  great economical choice for a variety of low-pressure  applications. 

The Gator, sold exclusively through BMD, is a patent pending spline mechanism that replaces existing “D” or keyed rotational  connections that quickly wear out. The spline design  eliminates slippage/slack, providing greater accuracy and  precision. Multiple Gator parts and accessories are available to fit a wide  variety of configurations.
