Multiquip 42637 Check Valve 1/4 MNPT X 1/4 FNPT 3 PSI - OEM Replacement Part

This check valve maintains proper fluid flow direction in power trowel hydraulic and lubrication systems, preventing backflow that can damage pumps and compromise system pressure. Rated at 3 PSI cracking pressure with 1/4" male NPT inlet and 1/4" female NPT outlet, this valve ensures one-way flow in critical control circuits.

Check valves are essential components in power trowel hydraulic systems, protecting expensive pumps from reverse flow damage and maintaining system integrity during shutdown cycles. The 3 PSI cracking pressure specification makes this valve ideal for low-pressure auxiliary circuits where precise flow control is required. Quality check valves prevent pressure loss, reduce pump cavitation, and extend the service life of hydraulic components.

Compatible with the following Multiquip power trowel models:

• HHXDF4
• HTX6H
• HTXG6DF
• STX6H
• STXDF
