Parker 7121KBN3UV00 Solenoid Valve 3/8 in Npt Brass

Product Description

The PARKER 7121KBN3UV00 is a direct-acting, normally closed solenoid valve designed for precise fluid and gas flow control in industrial and commercial systems. Built with a brass body and FKM fluorocarbon seal, it handles demanding media compatibility requirements. The valve features a 3/8-inch NPT port, a 1/4-inch orifice, and a Cv factor of 0.83, making it suitable for low-to-moderate flow applications. It accepts a wide range of voltages including 12 Vdc, 24 Vdc, 120 Vdc, 24/60 Vac, 120/60 to 110/50 Vac, and 240/60 to 220/50 Vac. Licensed HVAC technicians, plumbers, and industrial service technicians are the typical installers for this valve type.

This valve is suited for residential and light commercial fluid control applications where a normally closed, direct-acting solenoid is required. The multi-voltage coil compatibility makes it adaptable to a variety of control circuit configurations. With a minimum operating pressure differential of 0 psi, it can operate under no-flow or dead-end conditions, which expands its use in low-pressure systems. The maximum working pressure is 20 psi. Note that an integrated coil is required for complete valve assembly and must be ordered separately if not already included.

Key Features

• Direct-acting design operates at 0 psi minimum pressure differential — no upstream pressure required
• Brass body construction for broad fluid and gas media compatibility
• FKM fluorocarbon seal rated to 185 degrees F maximum operating temperature
• Wide multi-voltage coil compatibility: 12 Vdc, 24 Vdc, 120 Vdc, 24/60 Vac, 120/60 to 110/50 Vac, 240/60 to 220/50 Vac
• CSA Certified, UL Listed, and NEMA 4X rated for use in wet or washdown environments
• Normally closed default state ensures fail-safe shutoff on power loss

Compatibility

Designed as an OEM-style or replacement direct-acting solenoid valve for systems requiring a 3/8-inch NPT normally closed valve with FKM sealing and brass construction. Verify coil voltage matches your control circuit before installation.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic familiar with fluid control systems. Shut off all upstream pressure and de-energize the control circuit before servicing or installing this valve. Ensure the correct integrated coil is sourced separately if not supplied, as the valve requires it for complete operation. Follow applicable local codes and manufacturer torque guidelines for NPT threaded connections to avoid body damage or seal distortion.
