Parker 100913 Valve

The Parker 100913 Valve is a heavy-duty A9 hot gas bypass regulator designed for precise pressure management in commercial refrigeration and air conditioning systems. This pilot-operated regulator features a 7/8" ODF sweat connection and a full 7/8" port, engineered to modulate refrigerant flow and maintain a constant outlet pressure despite fluctuating loads. Built with a ductile iron body and brazed copper couplings, the Parker Sporlan 100913 is optimized for Range A applications, offering an adjustment range from 10" Hg to 120 psig. Its unique construction allows technicians to solder the valve into the line without disassembly, while still permitting full internal access for cleaning or maintenance. This internally equalized valve is critical for preventing compressor short-cycling, ensuring proper oil return, and maintaining tight humidity control in demanding HVACR environments.

• Internal Equalization: Eliminates the need for external capillary lines by sensing pressure directly at the valve outlet.
• Serviceable Design: The 7/8" ODF sweat ends allow for fast installation; the valve can be disassembled in-line for maintenance without cutting copper.
• Precise Modulation: Pilot-operated piston ensures high-sensitivity response to maintain set-point stability within 5 psi.
• Durable Construction: High-strength ductile iron body designed for a maximum working pressure of 450 psi.
• Broad Compatibility: Suitable for a wide range of common refrigerants in systems from 1.3 to 24 tons nominal capacity.

How do I adjust the pressure setting on the Parker 100913?
To adjust the Range A regulator, loosen the seal nut and turn the adjusting stem clockwise to increase the pressure or counter-clockwise to decrease it. One full turn corresponds to approximately 16 psi.

Can this valve be mounted in any orientation?
The A9 series can be installed in horizontal or vertical lines, provided the flow follows the direction of the arrow on the body. Ensure the adjusting stem is not positioned below the valve centerline to prevent oil trapping.

Is this regulator suitable for pump-down systems?
The standard 100913 A9 model does not provide positive shut-off. For pump-down control, a separate solenoid valve should be installed upstream, or the A9S version with an integrated electric shut-off should be utilized.
