Product Details:

Johnson Controls V46AR-1C water regulating valve is a 2 way pressure-actuated valve used on open or closed refrigeration systems to regulate the flow of head pressure while transferring water to a water-cooled condenser.

Working Mechanism:

  • Johnson Controls V46AR-1C valve employs a hydraulic actuator, composed of a diaphragm assembly and a control chamber. The diaphragm assembly is responsive to shifts in pressure and it reacts to alterations in the control signal.
  • The control signal, often presented as pressure, is fine-tuned according to the desired water flow rate. As the control signal shifts, it influences the pressure on one side of the diaphragm assembly.
  • Changes in pressure on one side of the diaphragm prompt its movement. This movement subsequently adjusts the valve's aperture, governing the water flow rate.

Frequently Asked Questions:

Q. What is the difference between a regulating valve and a reducing valve?

A. The contrast lies in the intended medium and purpose of these valves. A regulating valve is crafted to manage pressure within a gas medium, whereas a pressure-reducing valve is constructed to function with liquids. Both valves are typically in an open state, as evidenced by the arrow intersecting both the inlet and outlet ports.

Q. What are the three types of control valves?

A.

  • Manifold Valves
  • Ball Valves
  • Double Block and Bleed Valves

Q. How do I increase the water pressure in my tank with this water controlling valve?

A.

  • To increase pressure, a pressure pump connected to the discharge line can be beneficial. This pump will elevate both water pressure and the volume of water flowing from an overhead tank.
  • Ensure that the valve is in the correct position on the discharge line. A properly positioned check valve prevents water from flowing back into the tank, maintaining pressure.
  • The elevation of your overhead tank impacts the pressure. A higher tank placement can generate more pressure due to gravitational force.
  • Blockages or debris in the pipeline can hinder water flow and pressure. Regularly inspect and clean pipes, filters and valves to prevent obstruction.
  • Adjust the pressure pump settings to achieve the desired pressure level. However, be cautious not to exceed the system's design limits.

Q. How do I choose a control valve size?

A. Selecting the appropriate size for a control valve involves considering its operational range. Opt for a valve size that enables operation between 60 and 80 percent open during peak flow rates. Additionally, aim to avoid selecting a size that falls significantly below 20 percent open during minimum flow rates, whenever feasible.
