Valco Valves

Types

Valco valves are distinguished by a negligible dead volume and allow gas chromatographic determination with column switching, column sequence reversal, the sampling of definite gas volumes and so on.

Material and stability

  • valve body: Hasteloy C®, which has excellent resistant to most acids, including oxidizing acids with chloride ions and strong oxidizers such as ferric chlorides, or Nitronic 60 (stainless steel with high chemical resistance)
  • rotor: Valcon E (polyaryletherketone/PTFE composite)
  • temperature/pressure limit: 225 °C / 2.758 · 103 kPA (valves with higher values for temperature and pressure stability are available upon request)

Actuation options

  • pneumatic: for 2-position valves only; compressed air or nitrogen is recommended (275-550 kPA), operates up to 70 °C; requires a manifold solenoid valve assembly (see order no. in the table)
  • mikroelectric: microprocessor controlled, features a built-in RS-232 serial port

Scope of delivery

  • appropriate nuts and ferrules are supplied with all valves

 

 Vici2PositionsVentil

    two position valve with air actuator

 

 

Two position valves operate in two defined positions: "load" and "inject", position A and position B etc. They are available with 4, 6, 8, or 10 ports and can be installed to perform multiple functions, such as sample selection and column switching.

W type:  1/32"  fittings   0.25 mm Port ID for capillary GC (0.25/0.32 mm ID)
                 1/16" fittings   0.40 mm Port ID for capillary GC (0.53 mm ID) 

UW type: 1/16" fittings   0.75 mm Port ID for packed column GC
                  1/8"   fittings   0.75 mm Port ID for packed column GC

 

ViciMultipositionsVentil

 

    multiposition valve with microelectric actuator

 

 

 

Multiposition valves (6 to 16 positions) step incrementally through continuous revolutions (bi-directionally with the microelectric actuator) and are delivered with different flowpath configurations.

SD type ("dead-end") : selects one of 6-16 dead-end streams, directing it to a sample valve, pressure sensor, detector, column, etc.; the configuration is also used for fraction collection

SF type ("flow through"): is similar to the SD type, but it allows the non-selected streams to flow through individual outlets instead of a common outlet

 



Two Position Valves

Valves without actuation can be controlled by an Agilent air actuator.

Valves with air actuator require a manifold solenoid valve assembly (MSVA) to be controlled by the GC (see table, last line).

In the table below, order numbers are only given for valves with 4 ports and valve body made of Hastelloy C®.
If you wish to order another number of ports, please change the last two figures of the order no. as follows: "06" (6 ports), "08" (8 ports) or "10" (10 ports).
If the valve body should be made of Nitronic 60 instead of Hastelloy C®, the first figure of the order no. "0" should be replaced by "1".
Example: V 1018 01 08 = alve type W with valve body of nitronic 60, air actuator and 8 port
