A combination bypass and priming valve specifically designed for small cylinderfilling 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.
The model T166 is a moderate to high pressure build up valve with smooth-acting flow control. It offers bypass protection for pumps with capacities ranging from 30 – 100 gpm (6.8 – 22.7 m3/hr). Unlike the model B177, the model T166 modulates the flow by opening gradually as pressure builds up and bypasses the excess capacity smoothly and silently back to the supply tank. It also has a continuous internal bleed that assists in eliminating vapors.
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.
A low-pressure build-up bypass valve designed for applications requiring protection for positive displacement pumps. The continuous internal bleed is ideal for systems with air or electric operated internal valves.
4 Way Non Lubricated Valve
4-Way Non-lubricated Valve, a convenient and simple means of reversing flow direction to a compressor. Made of ductile iron body, complete with handle and flow direction indicator (1″ or 1-1/4″ NPT and “—Class 300 RF flange, 500 psig rating [34.5 bar g]).
