Bypass Valves

Model B166B Automatic, Dual-Purpose Bypass Valve

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.

  • Connections: 3/4” or 1” inlet & outlet
  • Differential pressure range: 25 – 225 psi (1.7 – 15.5 bar)
  • Maximum working pressure: 400 psig (27.6 bar g)
  • Capacity: 40 gpm (151 l/min)

B177 Differential Bypass Valve

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.

  • Connections: 2” or 2-1/2” inlet/outlet
  • Differential pressure range: 10 – 125 psi (.7 – 8.6 bar)
  • Maximum working pressure: 400 psig (27.6 bar g)
  • Capacities up to 390 gpm (1,476 l/min)
  • NPT or weld neck

Model ZV200 Bypass Valve

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.

  • Connections: 1.25″, 1.5″, 2″, & 2.5″ inlet & outlet
  • Differential pressure range: 41 – 150 psi (2.8 – 10.3 bar)
  • Maximum working pressure: 400 psig (27.6 bar g)
  • Capacity: 180 gpm (681 l/min) @ 70 psi (4.82 bar) of differential pressure
  • Capacity: 250 gpm (946 l/min) @ 120 psi (8.27 bar) of differential pressure
  • NPT or weld neck
