Actuator controllers and interfaces

Valco supports the actuation of valves with the controllers and interfaces listed below. Since our electric actuators are designed with more control and automation capabilities built in, most of the products in this section are for expanding the capabilities of our two position and multiposition air actuators.



Controllers

 Name   2 pos   Multi   Actuator   What it does 
 SVI
 Serial valve 
 interface
 •  •  Microelectric 
 Std electric
 Air
Controls actuators from a computer.
Can control up to 6 valves.
Air actuators require DVI interface.
 DVSP
 Digital
 valve 
 sequence
 programmer
 
 •  •  Microelectric 
 Std. electric
 Air
Programs valve switching for remote operation. For air actuators, provides pulsed and continuous control of solenoid air valves.

Solenoids

 Name   2 pos   Multi   Actuator   What it does 
 MSVA
 Manifold  solenoid
 valve  assembly
 (3-way  solenoids)

 •    Air Recommended for 2 position air actuators. Sends pulse of air to switch actuator from position to position.
 41E1
 4-way  solenoid
 air valve
   •  Air Simplest way to step multiposition air actuators.

Interfaces and accessories

 Name   2 pos   Multi   Actuator   What it does 
 DVI
 Digital
 valve
 interface
 •    Air Translates timed events from data system, integrator, or controllers such as DVSP or SVI into air pulses.
Includes LED position indicator.
 HSSA
 High
 speed  
 switching
 accessory
  
 •    Air For high speed switching.
 PFAF
 Position
 feedback
 •    Air Provides a contact closure for TTL logic level signals.
 PFW
 PFC
 Position
 feedback
 •    Manual For manual Valco W type and Cheminert C1, C2, and C4 series valves.
Continuous contact closure remote starts a chromatograph or data system.
