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 pumps. The patented vapor elimination system improves the pumping efficiency and minimizes wear by keeping the pump consistently primed. The B166B is smooth operating bypass with moderate to high pressure build-up and is available in 3/4″ and 1″ sizes.
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 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.
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.
MODEL 4-WAY VALVE
A four-way valve is a convenient and simple means of reversing the direction of flow to a compressor. The body is made of ductile iron and comes complete with a handle and flow direction indicator.
>> Connections : 1” or 1-1/4” NPT and 2” ANSI flanged (300#)
>> Non-lubricated, full port design with flow indicator
>> Reinforced PTFE seals and seats
>> Maximum Working Pressure : 500 psig (34.5 bar g)
The right-angle strainer minimizes pressure drop and is designed for liquid or vapor service. Comes complete with a ductile iron body, monel screen and steel plug.
>> Connections : 1-1/4” NPT
>> Mess : Available with liquid (14 mesh) or vapor (40 mesh) service
>> Maximum Working Pressure : 400 psig (27.6 bar g)
To protect the compressor from a lack of lubrication, a NEMA 7 pressure switch allows you to shut down the compressor if the oil pressure drops below 10 psi (0.69 bar). Available in 120 or 230 volt and can be used with magnetic starters up to NEMA Size 3.
Corken’s stainless steel, glycerine filled pressure gauges will mount to the compressor head or in the piping system.
>> Dual Scale : psi and kg/cm2
>> 0–400 psi (0–28 kg/cm2) range with a 5 psi (0.34 bar) increment
>> 2-1/2”, 270° dial with 1/4” NPT center back connection
AUTOMATIC LIQUID TRAP
If the application conditions involve liquid forming in the suction line during operation or the compressor is unattended, an automatic liquid trap is recommended. The automatic liquid trap has one NEMA 7 liquid-level switch and a drain valve. When liquid level inside the trap reaches a critical level, the liquid-level switch will shut down the compressor before any damage is incurred.
AUTOMATIC LIQUID TRAP (ASME CODE-STAMPED)
Applications with a large flow volume due to a long suction line and the compressor is left unattened, our ASME code-stamped automatic liquid trap is recommended. An ASME code-stamped automatic liquid trap has two NEMA 7 liquid-level switches and an alarm, relief valve, pressure gauge, demister pad, and drain valve. When liquid level inside the trap reaches a critical level, an alarm will sound and the liquid-level switch will shut down the compressor before any damage is incurred.
MECHANICAL LIQUID TRAP
A mechanical trap is useful when liquid is only present during start up. Our mechanical liquid trap comes with a mechanical float assembly and drain valve only.
