Choosing the Right 
Directional Ball Valve

Diverter Ball Valve

  • Separate Seats and Body Seals
  • One Flow Direction

The diverter valve is designed to accept media through a bottom inlet port and direct it out either of two outlet ports. It is commonly used for alternately diverting flow from a single source to two different lines, for example dumping operations in which one outlet permits media to flow from a common source to the process while the other outlet alternately dumps or recirculates excess media. The Diverter Ball Valve is available with two different porting configurations. Vl Porting is 90o operation for manual, pneumatic or reversing type electric actuation. The flow from the bottom inlet port cannot be shut off, only diverted to either of the two outlet ports. V2 Porting is 18011 operation for manual or 180o electric actuation. With this configuration, the flow can be shut off by simply operating the valve 90o. However, there is no mechanical stop arrangement for this position. The diverter valve is constructed with separate seat and body seal. 

3-Way Ball Valve 

  • One Piece Seat and Body Seal
  • Bi-Directional Flow

The 3-way ball valve provides greater flexibility in operation. Constructed with a one piece seat and body seal, the 3-way valve permits flow in both directions. It can function as a selector valve, 

alternately accepting media from either of two inlet sources and directing through a single outlet. Or, it may be used as a true 3-way valve, accepting media from two inlet sources for alternate discharge through either of two outlet ports. For example, in a pressurized line or system, the inlet port pressurizes or fills the system. The valve is then operated through its travel to allow the pressurized contents to be discharged through the second outlet port with the original outlet port now functioning as the inlet. 

The 3-way ball valve is available with two different porting configurations. Vl Porting provides 9011 operation for manual, pneumatic or reversing type electric actuation. With Vl Porting, alternate side ports are shut off at the 0o and 90o positions. V2 Porting shuts off one side at 0o, the opposite side at 180o and both sides at 9011, but there is no mechanical stop at 90o. V2 Porting permits Oo and 180o operation for manual or electric actuation only. Both positions can be shut off completely. 

Automation

Diverter and 3-way valves with Vl Porting (90o operations) may be automated with Series 34 or 39 pneumatic actuators or Series75 electric actuators. For V2 Portingconfiguration (180o operation), use the Series 75 electric actuator, also available with center-off option. Series 36 electric actuator is not suitable for use with Worcester Directional Ball Valves. 18011 pneumatic actuators are available through custom products.
