VC4043 Series Spring Return Valves

General
   The VC4043 series Spring Return Valves are used in Heating and air conditioning systems to control the flow of the heat transfer fluid. The fluid is typically hot or cold water, however treated water(Max.50% Glycol Solutions) applications are also permissible.

Spring return VC valve is one type of control valve that can do precise control refer to customer’s demands. Spring return actuator has the special function that if the power is off, the valve will return to original position by spring. This is a safe and energy saving function to customers.

In addition, this valve is capable of handling greater differential pressures without water-hammer.

WFS-1001-H WATER FLOW SWITCH
APPLICATION: The paddle type SPDT WFS series are designed to provide excellent performance where accuracy, reliability, and rugged construction are required used in liquid flow lines carrying water or any fluid neither harmful to brass and phosphor bronze nor classified as a hazardous fluids.

They can be wired to close one circuit and open a second circuit when liquid flow either exceeds or drops below the adjusted flow rate. The WFS series are recommended for liquid pressure and temperature as mentioned below and must not be used on lines carrying liquids below 0 C degree.

These series may be used on liquids with high salt or chlorine content but is not for use in hazardous atmospheres.

They may be also used outdoors but must be protected from weather or splashing water.

All series WFS flow switches are designed for use only as operating controls.

Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of user to add safety devices that protect against, or supervisory systems that warn of control failure.
