The model 93 is a range of high specification yet low cost Double Block & Bleed Valves for instrumentation applications that are available in any combination of Ball or Needle Valve assemblies.
The units are available in a full range of materials and options to meet the individual user requirements. The compact slim line design enable them to be used in wide range of applications particularly where space and weight must be kept to an absolute minimum.
All valve assemblies are housed within the single forged barstock body whilst the end connections incorporate the valve sealing face to ensure a single piece of material up to and including the first Primary Isolation Valve.
The end connectors are available in choice of screwed, weld or custom connections that are pinned to prevent accidental removal. A full range of testing, certification and documentation can be provided to suit the individual project requirement.

Many industrial applications require very robust valves which are resistant to thermal shocks and dusty or damp conditions.
They must be able to transport liquids such as steam of more or less good quality, high pressure hot water, hot or cold liquids, corrosive liquids, inert gasses or the vacuum.
Application sectors involved:
- rubber vulcanization
- dry cleaning and industrial cleaning
- iron and steel
- sugar
- boilers
The new 298/398 range with its stainless steel body, has all the qualities that these industries require.
- a resistance of 2 million cycles of saturated steam
- a working pressure up to 40 bar
- a bidirectionnel passage
- anti-pressure surge by design
- a large operating pressure range from 1 to 10 bar
- use of noble materials in order to work with liquids with temperatures from - 10 to more than 250°C and in atmospheres with temperatures from - 25 up to 180°C.
Thanks to its water and dust protection system, the valve when mounted in any position may be placed on the outside.
Robust but also highly effective, the 298/398 range is equipped with the latest technological advances which markedly increase its reliability (new generation valve). |

Valves raclables and components for scraped lines
Solutions of multi-products transfer and cleaning in place of pipings consisting in moving a tight mobile called scraper inside a piping in order to allow a complete draining, a cleaning in place of the line or a separation of fluids - compatible or not - transferred in the same line.
Components of scraping: stations of departure and arrival, scrapers, valves and t-pieces of distribution, valves 1,2 or 3 ways, valves in cross or H, manifolds and collecting raclables
Applications
ABB proposes the technique of scraping in following industries:
N lubricating and greases,
N paintings and varnish,
N paste and paper,
N chemistry of specialities,
N perfumes,
at all the stages of the process, for the transfer of raw materials (unloading of tankers), of semi-finished products (vat transfer to vat, proportioning) and of end products (transfer to the machines of conditioning).
Strong points
Exceptional output matter: 100% of the transferred product are used.
Quantity of liquid of washing minimized.
Network of piping simplified and small overall dimensions.
Security of the transfers of liquids because closed system.
Tool of process: change and proportioning of product without cross contamination.
Environmental protection: minimization and recovery of the effluents.

The versatile and lightweight Type TLD Valve is typically used for processing light density materials such as foods and pharmaceuticals and on rotating and mobile equipment where weight is a concern. It is available in a range of cast and weldable alloys including 316 stainless steel and Hastelloy. The sanitary version of the TLD Valve has full interior and exterior polishes. ANSI and DIN drilling patterns are offered in addition to the Gemco standard pattern. The valve is offered for dust tight, full vacuum and low-pressure (1 bar) services. Common installations of the TLD Valve include inlet/outlet valves on rotating or stationary blenders and Intermediate Bulk Containers.

Gemco Airlocks are designed to control the flow of material between two atmospheres or pressures. They typically consist of two standard Type T Valves connected by an intermediate chamber and are often used instead of rotary feeders, which are prone to high maintenance and leakage of material and gases. Normal cycling varies from one to three times per minute. Slower cycling is possible and nominal material flows of one half to ten cubic feet per cycle are available. Chamber purge, sight glasses, clean-out ports, and automatic cycling controls are among the custom engineering options available.
