Angle Body Piston Valve 1/2 in
This Red Hat 8290A384 is a normally closed angle body piston valve designed for drain and trap installations. It suits plumbing professionals and facility managers who need reliable on-off control for steam or water lines in indoor and outdoor environments.
5.7 Cv capacity and pressure limits
The valve delivers a flow coefficient of 5.7 through a 1/2 in orifice. It operates from 0 psi minimum differential up to 150 psi for steam and 240 psi for water, with a maximum fluid temperature of 366 Degrees F. Beyond those pressure or temperature limits the valve is not rated for service.
Bronze body and FKM seals
The bronze body and FKM seal material provide compatibility with steam and water media across the stated pressure and temperature ranges. The two-way, two-position configuration and normally closed start position mean the valve opens only when actuated, simplifying system design for drain and trap applications.

Questions about this item
Will the 1/2 in NPT threads on the 8290A384 mate with my existing bronze piping without adapters?
Yes — the valve body has 1/2 in nominal pipe size threads that match standard NPT bronze pipe, so it threads directly into your current line.
How can I verify the 8290A384 is actuating correctly once installed?
Apply inlet pressure up to 240 psi water or 150 psi steam; the piston should lift at 0 psi minimum differential and allow full flow with a 5.7 Cv coefficient.
Does the 8290A384 ship with a coil or connector, or must I order them separately?
The valve body is supplied alone; a compatible Red Hat coil and any required electrical connector must be purchased separately.
