Series ZC Characterized Ball Valves

IMPORTANT NOTE: Part number listed is a suffix to be added to full manual or actuated valve model number. Price listed must be added to complete valve assembly for total list price.



  • Based on the Plast-O-Matic “Engineered” True Blue Ball Valve with dual floating seats and Trunnion design
  • Choice of 15º, 30°, 45º, 60°, 90° V-Balls or Linear Flow Balls
  • Sizes from 3/8″ to 4″ in PVC, CPVC, Natural Polypro and PVDF
  • Manual or Actuated
  • Electronic flow control via Plast-O-Matic Air or Electric Actuators with optional 4-20mA or 0-10 DC digital positioning
  • Manual flow control via Plast-O-Matic Metering Manual Ball Valve


  • Ball design can be customized to provide virtually any flow rate
  • We use pre-tested combinations of holes and cuts to deliver precisely the type of flow your application requires
  • Custom slots or angles for atypical flow rates
  • Special valve materials available


Standard Flow Performance Curves with V-Balls

Note: For 3/4″ Valves with Mini Sanitary Connections, please refer to 1/2″ performance curves above.

To Specify a Standard Characterized Ball:

Begin with the regular EBVF or MBV part number, or Air Actuated Valve with Electro-Pneumatic Positioner, and add the appropriate suffix for the desired characterized cut:

Ball Cut Suffix
15º Angle V-Cut -C1
30º Angle V-Cut -C3
45º Angle V-Cut -C4
60º Angle V-Cut -C6
90º Angle V-Cut -C9

Linear Flow Cut

Full Port No suffix



For example, a 1″ threaded PVC/EPDM ball valve with a 30º characterized angle, including a 4-20mA control electric actuator would be EBVF1-3-100EPT-PV-C3

Standard V-Ball Cuts

Standard V-Ball Cuts are used to provide a pre-determined flow rate based on the angle of opening. Flow rate increases as an increasingly ascending curve as the valve is opened. Below are the V-Cuts offered as standard.

Linear Flow Cut

Standard Linear Flow Cuts are used to provide a pre-determined flow rate based on the angle of opening. Flow rate increases on a linear curve as the valve is opened.

Custom Cuts

Flow rates and actuation can all be customized to provide a unique control valve to meet your needs; below are examples of custom-designed valves for very specific flow requirements:
