Sporlan 4274-00 Valve

The Sporlan 4274-00, model R38E147M, is a heavy-duty, 2-way normally closed solenoid valve designed for high-performance refrigerant flow control in commercial refrigeration and large-scale air conditioning systems. This pilot-operated valve features 7/8" ODF sweat connections, allowing for efficient brazing without the need for disassembly, which protects internal components from heat damage during installation. Engineered for high-pressure environments, it is fully compatible with R410A, R22, R404A, and various HFC blends, maintaining a Safe Working Pressure of 650 psi.

Built with a rugged brass body and synthetic seating, the R38E147M 7/8" ODF NC solenoid ensures a tight seal and reliable shut-off under demanding conditions. It utilizes a PKC-2 coil (sold separately) and features a 7/16" port size, providing a liquid capacity of approximately 19.2 tons for R410A applications. This valve is a direct replacement for legacy units such as the Parker R30E157, offering a versatile drop-in solution for suction line, liquid line, or hot gas defrost service where precise electronic control is a requirement.

Key Benefits

• Optimized for R410A: High MOPD rating ensures reliable opening against high pressure differentials in modern HVACR systems.
• Extended Solder Connections: Features 7/8" ODF sweat ends that allow for direct brazing, reducing the risk of leak paths and protecting the internal synthetic seat.
• Synthetic Seating Design: Provides superior seat tightness and prevents refrigerant migration during the off-cycle.
• Interchangeable Coil System: Compatible with various PKC-2 AC and DC coils for flexible electrical field configurations.
• Pilot-Operated Efficiency: High flow capacity relative to its compact footprint makes it ideal for industrial refrigeration racks.

Common Questions

Does this valve include the solenoid coil?
No, the Sporlan 4274-00 is the valve body only. A PKC-2 type coil must be purchased separately to match your specific voltage requirements.

What is the maximum pressure rating for this 7/8" ODF solenoid?
The valve is rated for a Safe Working Pressure (SWP) of 650 psi, making it suitable for high-pressure refrigerants like R410A.

Can I install this valve in any orientation?
The valve should be installed in a horizontal line with the coil housing no more than 45° from the vertical position to ensure proper plunger operation and gravity return.
