Parker Hannifin 104559 Evaporator Pressure Regulator 1-1/8 Inch SportII

The Parker Hannifin 104559 is a commercial-grade evaporator pressure regulator from the SportII series, designed for demanding industrial and commercial refrigeration applications. This pilot-operated pressure regulator delivers precise control at desired set-points with excellent regulation even at light loads.

Key Features:

• 1-1/8 inch sweat connection size for reliable installation
• Pilot-operated design for close control and accurate pressure regulation
• Long-life stainless steel diaphragms eliminate bellows failure concerns
• Low pressure drop design maximizes system efficiency
• Few moving parts for reliable, long-term operation
• Constructed entirely with corrosion-resistant materials
• Interchangeable capacity cartridges for versatile applications
• All service accessible from the top for easy maintenance
• Sweat-in-place installation without requiring disassembly
• Tamper-proof adjustment screw prevents unauthorized changes

The SportII regulator features a precision-engineered diaphragm and valve assembly that ensures accurate pressure control across a wide operating range. Its piston and plug assembly handles reduced flow conditions effectively, controlling down to approximately 15% of the valve's maximum capacity. The compact design offers versatile mounting options and provides flexibility in space-constrained refrigeration installations.

Ideal for retrofitting additional evaporator capacity without requiring pipeline revisions, this pressure regulator is the reliable choice for industrial engineers and HVAC professionals seeking optimal system performance and efficiency in commercial refrigeration systems.
