van hồi lưu b166

The model B177 is low-pressure build-up bypass valve designed for applications that require protection for positive displacement pumps.

Benefit

• 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.
