Sporlan 904067P Valve

The Sporlan 904067P, designated as model HGBE-5, is a high-performance discharge bypass valve designed for precise capacity control in refrigeration and HVAC systems. As an externally equalized bypass valve, it modulates the flow of discharge gas to the evaporator to maintain a minimum suction pressure during low-load conditions. This helps prevent evaporator coil icing and ensures the compressor operates within its designed envelope, even when the thermal load drops significantly. Built for heavy-duty applications, this Sporlan HGBE-5 features a brass body and 5/8" ODF copper solder connections, making it an ideal choice for R-410A refrigeration systems and large-scale commercial AC units.

For technicians in the field, the 904067P offers an adjustable pressure range of 95 to 115 PSIG, with a factory setting typically at 105 PSIG. This direct-acting valve responds dynamically to downstream pressure changes, opening as suction pressure falls below the setpoint to inject metered discharge gas either into the evaporator inlet or the suction line. The 1/4" ODF external equalizer connection provides superior accuracy compared to internally equalized models, especially in systems with high pressure drops across the evaporator. Incorporating this hot gas bypass valve into your piping layout optimizes system cycle times and protects against the damage associated with short-cycling and liquid slugging.

• Precise Pressure Regulation: Features a 95/115# adjustable pressure range to maintain stable suction pressure and prevent coil frost-up.
• High-Durability Construction: Manufactured with a rugged brass body and 5/8" ODF copper connections for leak-free, long-term service in demanding environments.
• R-410A Compatibility: Specifically engineered to handle the higher operating pressures of R-410A systems with a maximum working pressure of 700 PSI.
• Improved Compressor Longevity: Eliminates frequent compressor cycling by providing effective capacity control during reduced load periods.
• External Equalization: The 1/4" external equalizer port ensures responsive modulation by sensing pressure directly from the suction line.

Is the HGBE-5 suitable for heat pump applications?
Yes, but when used in split-system heat pumps, a solenoid valve should be installed upstream to ensure the bypass is only active during the cooling mode.

How do I adjust the pressure setting on the 904067P?
Adjustment is made via the pilot valve screw; turning the screw clockwise increases the pressure setting (raising the suction pressure at which the valve opens).

Can this valve be installed in any orientation?
The HGBE-5 can be installed horizontally or vertically; however, it must be positioned so that it does not act as an oil trap in the bypass line.
