SIEMENS Globe Control Valve 1/2 in NPT

The SIEMENS 599-01121 is a globe-type control valve designed for water service in grounds maintenance and outdoor equipment systems. It features a 1/2 inch female NPT connection and carries UL recognition for safety compliance. The MZ series valve body measures 2-1/4 inches in height, 2-6/8 inches in width and 1-5/16 inches in depth. It is supplied new and ready for installation.

Suits installers needing a 1/2 inch NPT globe

This valve suits technicians and maintenance teams regulating water flow in compatible manifolds or outdoor equipment circuits where a 1/2 inch NPT globe valve with UL listing is specified. It is not for buyers who require a different connection size, a different valve type such as ball or butterfly, or a valve rated for fluids other than water. The 1.6 and 60 and 250 values noted in the data sheet must match the system design parameters.

Verify connection size

Confirm that the existing piping uses a 1/2 inch female NPT thread to match the valve inlet and outlet. Check that the system operating pressure and temperature align with the 1.6, 60 and 250 figures provided in the specifications. Ensure the physical envelope of 2-1/4 by 2-6/8 by 1-5/16 inches fits the allocated space in the manifold or equipment housing.
