Sporlan 164970P Valve

The Sporlan 164970P is a heavy-duty, externally equalized thermostatic expansion valve (TEV) engineered for high-capacity commercial refrigeration and air conditioning systems. Part of the field-proven EBS series, the EBSJE-12-JW model is specifically designed for R-134a refrigerant, providing a nominal capacity of 12 tons to ensure optimal evaporator efficiency. This valve features a 7/8" ODF inlet and a 1-3/8" ODF outlet, utilizing extended copper connections that allow for straightforward brazing without the need for valve disassembly. Built with a balanced port design, the EBSJE-12-JW maintains stable superheat control even under widely varying head pressures and evaporator loads, making it a reliable choice for supermarket rack systems and large-scale industrial chillers. The stainless steel diaphragm and welded element construction offer superior durability against pressure fluctuations, while the replaceable thermostatic element allows for convenient field service and internal inspection. This Type EBS valve ensures precise refrigerant metering, protecting the compressor from liquid slugging while maximizing the active coil surface.

Key Benefits

• Balanced Port Construction: Prevents changes in pressure drop from influencing valve operation, ensuring consistent superheat in variable conditions.
• R-134a Optimized: Specifically calibrated with a JW thermostatic charge for precise 12-ton capacity control in medium and low-temp applications.
• Standard ODF Solder Connections: Features 7/8" x 1-3/8" ODF extended fittings for secure, high-strength silver-soldered joints.
• Field Serviceable Design: Equipped with accessible internal parts and a replaceable power element for simplified maintenance and cleaning.
• External Equalization: Effectively compensates for pressure drops across the evaporator to maintain peak system performance.

Common Questions

Can the EBSJE-12-JW be used with R-404A or R-22?
No, the 'J' designation indicates this valve is specifically charged for R-134a. Using it with unsupported refrigerants will lead to improper superheat and potential system failure.

Is this valve suitable for bi-directional flow?
The Sporlan EBS series with balanced ports is capable of bi-directional operation in certain configurations, though it is primarily optimized for consistent flow in large commercial DX systems.

How do I adjust the superheat on this model?
This is an externally adjustable valve. Rotating the adjustment stem allows technicians to fine-tune the superheat setting based on real-time suction line temperature and pressure readings.
