C52
Cheminert Model C52 injectors are integrated motor/valve assemblies designed specifically to be built into an OEM system. Control is simplified to require a single contact closure; the injector's position is determined by whether the closure is held high or low.
Valves include 1/16" stainless nuts and ferrules. Order sample loops separately.
Available in 4 port, 6 port, 8 port, and 10 port valves.
Basic Design
The Cheminert design by VICI Valco Instruments involves a flat rotor which is engraved with slots to connect the ports and a stator which is held against the rotor at a constant, preset force.
When repairs are required, just take out two or three screws, replace the rotor, and put the screws back in and tighten them. No adjustments are possible, much less required. Other advantages of the design include easy panel mounting, low actuating torque, and compact size.
