The LEGEND VALVE 101-541 is a 1/4-inch T-800T series ball valve fitted with a T-handle operator, designed for reliable shut-off service in plumbing, HVAC, and light industrial piping systems. Rated at 125 WSP (working steam pressure) and 400 WOG (water, oil, gas), this valve delivers full-port flow control in a compact quarter-turn design. The T-handle provides positive tactile feedback and easy operation in tight spaces. This valve is a direct functional replacement for conventional pet cocks in a wide range of service applications. Licensed plumbers and HVAC technicians are the primary installers.
The 101-541 is suited for residential and light commercial installations where a low-profile, durable shut-off is required on small-diameter lines. Its T-800T series designation and ISO-9002 manufacturing standard indicate consistent dimensional tolerances and material quality, making it a dependable drop-in for pet cock locations on boilers, water heaters, drains, and instrument connections. The 1/4-inch size fits common sampling, drain, and purge port applications across plumbing and hydronic heating systems.
Designed as an OEM-style replacement for conventional pet cocks on residential and light commercial plumbing, hydronic, and HVAC piping systems with 1/4-inch connections.
Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the system fully before removing any existing valve or pet cock. Apply appropriate thread sealant rated for the service media — confirm sealant compatibility with steam, gas, or oil as applicable. Do not overtighten; use a backup wrench on adjacent fittings to avoid stressing the piping.
