Globe valves

Powermite Globe Valve

A complete line of globe valves for any HVAC application

Siemens offers a large selection of globe valves to suit any heating or cooling application using water or low-pressure steam. This complete portfolio allows you to meet your design needs and helps ensure that heating and cooling systems are operating at optimum levels. Siemens globe valves have the highest close-off in the industry. This high close-off maintains operations to support actuator functionality in the most rigorous hydronic applications. All Siemens globe valves are offered with 100:1 rangeability, giving our offering the highest level of control in the market. The larger rangeability allows for finer control tuning of the system and helps eliminate control valve hunting which leads to premature failure. For wider selection, reliable shut off and precision control, choose Siemens globe valves.

Range from ½- to 1-inch sizes with Cv from 0.4 to 10.  These valves can be used to control hot and chilled water with up to 50% glycol and low-pressure steam <15 psi over a temperature range of 35°F to 250°F.

Range from ½- to 6-inch sizes with Cv from 1 to 400.  These valves control hot and chilled water with up to 50% water-glycol and saturated steam up to 100 psi and over a temperature range of 35°F to 337°F. 

These 2-way and 3-way valves range from ½- to 1¼-inch sizes with Cv from 0.9 to 16. Used to control hot or chilled water with up to 50% glycol and low-pressure steam <15 psi with a maximum temperature of 250°F.

Largest selection

Siemens offers the largest selection of globe valves to suit any heating or cooling application using water or low-pressure steam. Globe valves are offered ranging from 1/2" to 6" sizes with multiple Cv options per size. The large portfolio allows customers to flexibly select the product that best fits their design and needs.

High close-off

With our 200 PSI high close-off offering, Siemens globe valves ensure actuator functionality in some of the most rigorous hydronic applications.

For applications up to 200 PSI differential pressure, the high close-off globe valve actuators will maintain operations to ensure the hydronic system is working properly. This in turn assures that the heating and cooling system is operating at its optimum level.

Accurate flow control

Globe valves have linear stroke design and provide 100% flow controllability. Globe valves have no dead band.

Field repairability

Siemens Flowrite valves are designed to be field repairable in the event of operational issues. Our kits feature a higher close-off rate, rangeability, and a larger selection offered in multiple sizes and configurations to allow for field repairs without intensive labor and time compared to other globe valves on the market. 

Free factory assembly and valve tagging

Valves and valve actuators are assembled and tagged for direct delivery to any jobsite, free of charge. All you do is specify each valve’s location when placing your initial order and we will tag them before shipping to save you installation time and expense. For questions call 800-516-9964 or email bgcustomersupport.us.sbt@siemens.com
