Parker Hannifin 903413P ADRSE-2 Discharge Bypass Valve 5/8" ODF 0-80 PSI

The Parker Hannifin 903413P ADRSE-2 is a direct-acting discharge bypass valve designed for industrial refrigeration and air conditioning systems, featuring a 5/8" ODF (sweat) connection for straightforward installation. This modulating control valve provides an economical method of compressor capacity control by automatically bypassing the required amount of discharge gas to the low side to maintain the desired minimum evaporator pressure.

Key Features:

• Responds to downstream pressure changes and opens when evaporator pressure falls below the valve setting; at normal loads, the valve remains closed and the system operates conventionally
• Adjustable pressure range: 0 to 80 PSI
• 5/8" ODF solder connections
• 1/4" external equalizer port
• Brass body construction with ODF connections for durability
• Factory tested to ensure positive leak-free performance

This valve is applicable on any refrigeration or air conditioning system that operates during periods of low load, which can result in coil icing or short cycling. The valve automatically bypasses discharge gas to maintain desired minimum evaporator pressure during low-load conditions.

Applications: Ideal for commercial refrigeration systems, walk-in coolers, air conditioning applications, and anywhere compressor capacity control is needed below the last step of cylinder unloading.
