Valve Oven Overview

Options

The type of valve enclosure can be selected among three different options depending on the analytical requirements.

1.TRACE GC Ultra Valve Oven

It provides an additional isothermal heated zone to accomodate valves and columns. It consists of an inner heated enclosure and an external unheated area. The former is designed to house up to four heated valves, restrictors and 1/8” OD packed columns. The latter houses up to two valves and pressure regulators. This option is therefore particularly suitable for applications such as natural gas or refinery gas analyses where, together with the GC column oven, an additional isothermally heated area is required for gas sampling, column switching, storing or sample cutting valves. It can accommodate up to four constant pressure regulators, up to eight needle valves, plus front and rear sample and carrier gas inlets/outlets.

2.TRACE GC Ultra Valve Box for Up to Six Valves

This version is the same as previous option (TRACE GC Ultra Valve Oven) but without heating elements. It provides an additional cold zone to accommodate up to four gas sampling/switching valves, up to two valves for liquid sampling, restrictors and 1/8” OD packed columns.

It is therefore particularly suitable for engineered applications that can be exploited at ambient temperature, for which multi-column and/or multi-valve configurations (sampling, switching, storing or heart-cutting) are required. It can also accomodate up to four constant pressure regulators, up to eight needle valves, plus front and rear sample and carrier gas inlets/outlets

3.TRACE GC Ultra Valve Box for Up to Two Valves

This version is the same as previous option (TRACE GC Ultra Valve Box for Up to Six Valves) but can accomodate ONLY up to two valves, thus providing a customized solution for not highly demanding engineered applications. This version does not include any electronics; the drivers for the two three-way- valves controlling the pneumatic actuators are installed on the TRACE GC Ultra.

It is able to accept restrictors and 1/8“ OD packed columns; it can also accommodate up to four constant pressure regulators, up to eight needle valves, plus front and rear sample and carrier gas inlets/outlets.
