GAS COOLER/FLASH GAS BYPASS VALVESThe Sporlan GC and FGB valve families are stepper motor driven pressure regu-lating valves, designed specifically for transcritical R-744 refrigeration systems.

The GC -10, -20, -30, -40, & -50 are applicable as gas cooler / condenser hold-back valves and can also be applied as flash tank pressure regulating valves (flash gas bypass). The flash gas bypass valve capacity range is expanded with the use of the FGB-60 & -70 valves in this application. All GC and FGB valves have 2500 steps of movement and synthetic seats to provide great resolution and ensure tight shutoff.

CONTROLSThe Sporlan GC and FGB valves can be controlled and driven using the Parker Sporlan PSK3LX CO2 Controller and PSD4 Interface Board/Positioner. The PSK3LX CO2 Controller optimizes transcritical and subcritical CO2 system COP through control of the GC & FGB valves. This control system can drive two valves for Gas Cooler and Flash Tank control.

The PSD4 Interface Board accepts a 0-10VDC or 4-20 mA signal from the PSK3LX or other gas cooler/system controller. The PSD4 translates this signal into a suitable stepper motor sequence to position the valve proportionally.

The PSS4B Backup Power Module provides reserve power for one full valve closure in the event of a power loss. This serves to isolates the refrigerant charge and minimize CO2 refrigerant loss if system pressure exceeds the system’s pressure relief valve setting.

VALVE CONSTRUCTIONThe GC family features a cartridge construction, where the valve port is integrated into the stepper motor actuator assembly. Therefore, the valve family can be broken into two distinct pieces: the bodies and the cartridge assemblies.

The valve bodies are available with three connection sizes for butt or tube / socket welding: ½ inch (12.7 mm), ¾ inch (19.05 mm) and 1 inch (25.4 mm). The five cartridge assemblies contain the valve pin and port, and determine the ultimate valve capacity. The three bodies are compatible with all five cartridge assemblies, and can be paired in any combination to best fit the system piping and capacity requirements.

There is a screen located around the port inlet that is a part of the cartridge assembly, but can be removed for service if necessary.

The FGB family has a slightly different construction that minimizes pressure drop through the valve at full

stroke. To achieve this result, the port is not inte-grated into the stepper motor actuator assembly, but is mounted directly into the valve body.

There is a single valve body available with a 1 inch (25.4 mm) connection for butt welding. Because

this valve is installed in the low pressure side of the system, the option is also available to utilize an 1-1/8

inch (28.58 mm) ODF or 1-3/8 inch (34.93 mm) ODM braze joint.

There are two stepper motor actuator assem-blies that contain the valve pin, and must

be matched with the corresponding port. The port is threaded into the valve body, and is removable to service the port or to perform a capacity conversion.
