Parker BVAH20NSS1N Ball Valve 1-1/4 in Fnpt Carbon Steel

Product Description

The PARKER BVAH20NSS1N is a standard manual ball valve designed for flow isolation and shutoff in piping systems. Built with a carbon steel body and carbon steel trim, this valve delivers reliable service in industrial and commercial applications. The 1-1/4 inch female NPT (FNPT) inlet and outlet connections allow straightforward threaded installation into existing piping. A lever-style handle provides quick quarter-turn operation, giving technicians clear open and closed positions at a glance. Delrin seat material supports a positive seal under normal operating conditions. Weighing 7 pounds, this is a full-size industrial valve suited for qualified piping trades.

This ball valve is intended for use in industrial, commercial, and mechanical piping systems where manual flow isolation is required. Typical installations include HVAC hydronic systems, compressed air lines, process piping, and general fluid handling lines where a 1-1/4 inch threaded shutoff is specified. Licensed plumbers, pipefitters, and HVAC mechanics are the primary installers. The FNPT x FNPT end configuration fits standard NPT-threaded pipe and fittings without adapters.

Compatibility

Designed as an OEM-style replacement or new-installation manual ball valve for 1-1/4 inch NPT threaded piping systems in industrial, commercial, and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC mechanic in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Depressurize and drain the system fully before removing any existing valve or making new connections. Apply thread sealant or PTFE tape to male NPT threads per standard practice, and avoid over-tightening, which can crack fittings or distort seals. Confirm the lever handle has full range of motion and reaches a clear stop in both the open and closed positions before returning the system to service.
