Dani HSS-86.50 Pressure and Vent Valve for 7694E and G1888 Headspace Samplers

Description

Dani HSS-86.50 pressure and vent valve is supplied by Longi as a separately identified replacement item for industrial or laboratory equipment service. This is a pressure and vent valve listing, not a complete chromatograph or a heated transfer-line listing. The photographed component was described as suitable for Dani HSS-86.50 and HSS-86.50 Plus headspace equipment and for related Agilent 7694, 7694E and G1888 service applications. Its function in a system should be confirmed from the buyer’s own pneumatic diagram and existing assembly.

Dani HSS-86.50 pressure and vent valve identification

This is a pressure and vent valve listing, not a complete chromatograph or a heated transfer-line listing. The photographed component was described as suitable for Dani HSS-86.50 and HSS-86.50 Plus headspace equipment and for related Agilent 7694, 7694E and G1888 service applications. Its function in a system should be confirmed from the buyer’s own pneumatic diagram and existing assembly.

Function and application context

In a headspace sampler, the pressure and vent path manages gas handling around the sample cycle. The visible valve body, ports and fittings are therefore more important for matching than a broad family name. Buyers replacing a failed part should compare the old assembly side by side with the product images, including port direction, tubing connections, mounting points and any labels or valve markings.

How to match the correct part

HSS-86.50 equipment can contain several components with related names: valves, heated lines, switches, arms and sampler assemblies. This page covers the pressure and vent valve only. It is not a listing for a transfer line or a generic chromatograph spare. Confirm the exact instrument configuration, gas connections and service documentation before ordering.

Model matching should always be completed before payment or installation. Product titles are written to make the individual reference easy to find, while the physical part, labels and photos remain the final evidence. Longi can review those visible details with the buyer before dispatch, but this does not replace the equipment manufacturer’s documentation or site safety procedure.

Condition and inspection information

The item is a photographed industrial/laboratory spare part. Visible condition is represented by the images supplied with the listing. Longi checks physical condition and packing before shipment. Where a current stock item can be functionally checked, the available check is confirmed with the buyer; no unverified analytical performance claim is made by this page.

For all used or removed equipment parts, buyers should allow for normal cosmetic evidence of storage or previous installation. The listing photographs are deliberately retained as part of the identification record. If a detail is important to your repair, ask for confirmation before ordering rather than assuming that a similar family name means the same revision.

Typical use

This valve assembly may be useful to laboratory maintenance engineers, analytical-instrument service companies and facilities with a Dani or compatible Agilent headspace sampler that needs pneumatic-component replacement. It is particularly relevant where the original valve can be identified by the same physical configuration.

Before ordering

Before ordering, send photos of the removed valve, the sampler model label, the tubing layout and any part number. Longi can compare visible features and prepare protective packing for international delivery.

• Match the full model or part reference, not only the equipment family.
• Compare connectors, fittings, mounting points and the actual product images.
• Keep the removed part available until the replacement has been identified and installed.
• Confirm any required test, firmware, configuration or safety checks with the qualified installer.

Packing and international delivery

Longi packs electronic modules, laboratory components and control parts according to their shape and fragility. Protective material is used around boards, mechanical assemblies, cables and exposed connectors. Buyers can request a final model comparison or packing confirmation before shipment. International delivery is arranged after the order details, recipient information and any required quotation are confirmed.

FAQ

How is this listing distinguished from a similar product? Is this the heated transfer line? No. This page is only for the pressure and vent valve assembly. The heated transfer line is a different spare item with different connections and a different function in the headspace workflow.

Can Longi confirm suitability? Longi can compare labels, photographs and visible installation details supplied by the buyer. The final decision must be based on the actual equipment, qualified service judgement and the precise part reference.
