07 LPG Accessories Bypass Valves

B166BB177ZV200

B166B (3/4″, 1″) Automatic Dual-Purpose Bypass Valve

Typical Application: on all cylinder filling pumps as well as aerosol propellant feed pumps.

A combination bypass and priming valve specifically designed for small cylinder-filling type pumps, especially of the regenerative turbine type, such as the Corken Coro-Flo pump series. The patented vapor elimination system keeps liquefied gas pumps primed to increase system reliability and decrease pump and seal wear. The B166B is a smooth operating bypass with moderate pressure build-up.

ZV200 (2″) Bypass Valve

Typical Applications: used for both truck and stationary applications for loading and unloading.

A low-pressure build-up bypass valve designed for applications requiring protection for positive displacement pumps. Specifically designed for protecting pumps with capacities up to 250 gpm (56.8 m3/hr). The continuous internal bleed will assist in the operation of systems with “air” or “electric” operated internal valves.

B177 (2″, 2-1/2″) Differential bypass Valve

Typical Application: in liquefied gas bulk plant installations for loading and unloading pumps.

A low-pressure build-up bypass valve specifically designed for applications requiring protection for positive displacement pumps in the 50′ to 350 gpm (11.4 to 79.5 m3/hr) range. It can also be used as a differential back-pressure valve to assure adequate pressure on meters, etc. To properly function, this valve requires a pressure sensing line from the storage tank.
