HVAC Valves
A valve is a device that regulates the flow of a fluid by opening, closing or partially obstructing a passageway.

Modern control valves operate on sophisticated automation systems that are based on external input. The valve is used to regulate flow based on previously-determined setpoints or variables, for example. These types of valves require an actuator, which will position the valve accurately depending on its input and setup. Actuators can be electrical, hydraulic or pneumatic, depending on the application and its environment.

Valves are critical in HVAC applications, and paired with actuators are designed to regulate the flow of both hot and chilled water in HVAC systems. Ball valves are most common for HVAC systems, able to regulate flow in several different directions with just one fitting.

SAX Series Image
  • Electro-Mechanical Switches Protect Components from Overload and Stall Condition
  • Automatic Calibration (SAX61.03U Only)
  • Visual and Electronic Stroke Indication
  • Proportional or Floating (3P) Control
  • 180 lb (800 N) Nominal Force
  • Direct-Coupled Installation
  • Non-Spring Return
  • Maintenance-Free
  • Manual Override
Designed for use with Pressure Independent Control Valves with a 3/4-inch (20 mm) stroke. The SAX Electronic Actuator requires either a 24 VAC or 24 VDC supply and receives a 0 to 10 VDC or 4 to 20 mA control signal to proportionally control the valve or a floating control signal to provide floating control of the valve.
GDE Series Image
  • Chrome-Plated Ball and Brass Stem
  • Non-Spring Actuator
  • Two Way Ball Valve
  • Normally Open
  • 200 PSI
V5011N Series Image
  • Direct and reverse acting
  • Sizes range from .5-2 inches
  • High pressure steam models with stainless steel trim
These valves are used for two-position or modulating control of steam and water and glycol solutions in heating or cooling systems. These valves designs provide equal characteristics of flow for close control of water and linear characteristics of flow for close control of steam or chilled water.
  • Not suitable for combustible gases
  • Spring-loaded, self- adjusting packing
V4044 Series Image
  • Compact construction
  • Manual opener for power failure
  • Suitable for heating and cooling applications
These on-off and diverting line voltage valves consist of an actuator motor and valve assembly for controlling hot or chilled water. All models may be installed without disassembling the valve.
