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.
