The Sporlan 900598 is an adjustable crankcase pressure regulating valve designed for use in refrigeration and air conditioning systems. This valve is part of the Sporlan CROT-10 series and connects using a 7/8 inch ODF fitting. It is built from brass for durability and corrosion resistance in demanding refrigerant environments. The valve regulates crankcase pressure within a range of 0 to 60 psig, protecting the compressor from excessive suction pressure during startup and operation. HVAC and refrigeration technicians rely on crankcase pressure regulators to prevent compressor slugging, which can occur when liquid refrigerant or oil floods back into the compressor. By limiting the pressure differential across the compressor, the valve extends equipment life and reduces costly repairs. The Sporlan 900598 is an adjustable model, giving technicians precise control over the pressure setpoint to match the specific requirements of each system. It is compatible with common refrigerants used in commercial and industrial refrigeration applications. The brass construction ensures the valve holds up under continuous pressure cycling and exposure to refrigerant oils. With a length of 12.0 inches, a width of 7.0 inches, and a height of 2.4 inches, this valve is sized for standard commercial refrigeration installations. It weighs 2.46 pounds per unit. A strainer rated 825-7 is associated with this valve to help keep the system clean. This valve is a dependable choice for service technicians, refrigeration contractors, and HVAC professionals performing compressor protection work on commercial refrigeration equipment.
The Sporlan 900598 crankcase pressure regulating valve delivers reliable compressor protection with an adjustable 0 to 60 psig range and a brass 7/8 inch ODF design built for commercial refrigeration service.
