Working Mechanism

  • Johnson Controls 3-way ball valves have three ports: an inlet, an outlet and a third port called the diverter or common port.
  • The ball inside the valve can be rotated using the handle or actuator. Its position determines the flow direction.
  • Position 1 - Straight Flow: When the ball is in one position, it allows fluid to flow straight from the inlet to one of the outlets, blocking the other outlet.
  • Position 2 - Diverted Flow: When the ball is turned to a different position, it diverts the flow from the inlet to the other outlet, blocking the original outlet.
  • Position 3 - Closed: In a third position, the ball can be turned to block both outlet ports, preventing any flow through the valve.

Features

  • Johnson Controls globe valves are available in bronze and cast iron construction variants for corrosion resistance.
  • They are available with either brass or stainless steel trim and are suitable for saturated steam applications up to 100 psig.
  • These valves have been factory tested to ensure tight shutoff and leakproofing, ensuring occupant comfort and energy conservation.

Standards and Approvals

  • ANSI Class 250

Frequently Asked Questions

How do you select the right three-way ball valve for a specific application?

Factors to consider include the type of fluid, pressure & temperature requirements, flow rate and the desired flow pattern (diversion or mixing).

What is the difference between a manual and an automated (actuated) three-way ball valve?

A manual three-way ball valve is operated by hand using a lever or handle, while an automated valve is controlled electronically, pneumatically or hydraulically using an actuator
