Product Description

The PARKER XV590P-8 is a 2-piece standard manual ball valve designed for inline flow control in plumbing, HVAC, and industrial fluid systems. Built with a brass body and brass trim, it provides reliable shutoff in a compact form. The tee-style steel handle gives technicians a positive grip for quick quarter-turn operation. Rated to 250 psi maximum working pressure, this valve handles demanding service conditions. Reinforced PTFE seats and seals deliver chemical resistance and long service life across a wide temperature range, from -50 degrees F to typical system operating temperatures. Installed by licensed plumbers and HVAC technicians wherever a dependable manual shutoff is required.

The XV590P-8 suits residential and light commercial applications including hydronic heating lines, chilled water circuits, compressed air drops, and general plumbing branch lines.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and IPC guidelines. Depressurize and drain the affected line before removing or installing any valve. Apply thread sealant or PTFE tape to male threads per standard practice — do not overtighten, as brass fittings can crack under excessive torque. Confirm handle orientation relative to pipe flow direction before returning the system to service.
