Carrier ME19S270-HP Refrigerant Solenoid Valve 7/8" ODF R410A Less Coil

The Carrier ME19S270-HP is a pilot-operated refrigerant solenoid valve engineered for use in commercial and residential refrigeration and air conditioning systems. Rated for R410A high-pressure service, this normally closed valve features a 7/8" ODF (Outside Diameter Flare) solder connection with extended solder ends for straightforward field installation. Also cross-referenced as Sporlan part number 3591-00.

Key Features:

• Connection Size: 7/8" ODF solder (sweat) connection type
• Port Size: 19/32" internal port
• Operation Type: Normally closed (NC), pilot-operated disc construction
• Maximum Working Pressure: 700 PSI — rated for R410A high-pressure systems
• Manual Lift Stem: Included for manual override capability
• Overall Length: 7.13 inches (less coil)
• Refrigerant Compatibility: R410A, R22, R134a, R401A, R402A, R404A, R407C, R502, R507
• Required Coil: Type MKC-2 electrical coil (sold separately)
• Mounting: Horizontal, on-side, or vertical installation — flexible positioning

The pilot-operated design requires very low pressure differential (as little as 1 PSI) for full valve opening, making it well-suited for suction line service as well as liquid and discharge gas applications. Tight sealing is achieved through synthetic seating material. The valve body is constructed for the elevated working pressures required by R410A refrigerant while remaining compatible with a broad range of lower-pressure refrigerants.

This valve ships less coil — the Type MKC-2 coil must be ordered separately. Cross-references: Sporlan ME19S270HP, Sporlan 3591-00.
