Johnson Controls SEP91A-601R Power Element

When you're dealing with a 3/4" water regulating valve that won't modulate, the Johnson Controls SEP91A-601R Power Element is the professional-grade solution for a field rebuild. Specifically engineered for the V46 Series pressure actuated water regulating valves (including V46AC and V46N models), this replacement sensing element restores precise head pressure control without requiring a full valve body replacement. It features a Style 5 pressure element design, typically supplied with a 1/4" male SAE flare connector for seamless integration into your refrigeration or cooling system's pressure line.

The SEP91A-601R is built for the rigors of commercial HVACR environments, operating within a standard pressure range of 70 to 260 psig. By accurately sensing refrigerant pressure, it allows the valve to modulate water flow to the condenser, ensuring optimal thermal transfer and system efficiency. This component is essential for preventing high-pressure cutouts and maintaining stable condensing temperatures in 3/4" NPT threaded valve applications. For technicians performing maintenance, verify if a SEC99AA capillary kit is required to complete the installation if the original tubing is compromised.

• Optimized Compatibility: Designed specifically for 3/4" V46, V46N, and V48 series pressure-actuated valves.
• Durable Construction: Heavy-duty bellows assembly provides reliable modulation in commercial refrigeration and cooling systems.
• Broad Pressure Range: Effectively manages condensing pressures across a 70-260 psig spectrum.
• Cost-Effective Repair: Facilitates a top-side rebuild, eliminating the labor and hardware costs of replacing the entire valve body.
• Standardized Connection: Features a 1/4" male SAE connector (Style 5) for straightforward field replacement.

Which valve models are compatible with the SEP91A-601R?
This power element is primarily used with 3/4" V46AC and V46N pressure-actuated water regulating valves. Always cross-reference your specific valve's code number before installation.

Does this element include the capillary tubing?
The SEP91A-601R is typically supplied with a 1/4 inch male flare fitting. If your application requires a new capillary line or a different connection style, you may need to order a SEC99AA capillary kit separately.

What is the maximum operating pressure for this sensing element?
While the operating range is 70 to 260 psig, these elements are designed to withstand standard commercial refrigerant pressures. Ensure your system does not exceed the valve body's 320 psig maximum bellows pressure rating.
