The model B166B is a combination bypass and priming valve designed specifically for small cylinder filling pumps such as Corken’s Coro-Flo® regenerative turbine and side channel pumps. The patented vapor elimination system improves the pumping efficiency and minimizes wear by keeping the pump consistently primed. It is a smooth operating bypass with moderate to high pressure build-up and is available in 3/4″ and 1″ sizes.
Typical Applications: Ideal for small cylinder filling pumps and aerosol propellant feed pumps.
The model B177 is low-pressure build-up bypass valve designed for applications that require protection for positive displacement pumps. It is ideal for capacities ranging from 100 to 350 gpm (22.7 to 79.5 m3/hr). It can also be used as a differential back-pressure valve that assures adequate pressure on meters. To function properly, this valve requires a pressure sensing line from the storage tank. Available in 2″ and 2-1/2″ sizes.
Typical Application: Used in liquefied gas bulk-plant installations utilizing loading and unloading pumps.
The model ZV200 is a 2″, low-pressure build-up bypass valve designed for applications that require protection for positive displacement pumps. It is ideal for capacities up to 250 gpm (56.8 m3/hr). The model ZV200 has a continuous internal bleed that helps operate systems containing an “air” or “electric” operated internal valve.
Typical applications: Used for truck and stationary applications utilizing medium to large capacity loading and unloading pumps.
