Gaskets for Clamp Fittings are available in several different materials, EPDM, Silicone, Vition®, and Viton®. Lightweight and heavy-duty clamps complete the unions. EFT’s Clamp Fittings meet all 3A requirements.
The Small flange or KF standard (DIN 28403, ISO 2961) is the standard connection for vacuum pipes up to the nominal diameter of DN50 used in low, fine and high vacuum.
A seal is positioned between the flanges. The seal consists of a centering ring and the O-ring stretched upon. The flanges are held together by a clamp. The clamp has an inclined interior surface adequate to the conical outer surface of the flanges.
Usually centering rings and standard clamps are used with wing nuts. They enable a quick and easy assembly without any tools. Trapped centering rings and special clamps or clamp chains are offered for special applications.
Claw clamps or so-called bulkhead clamps are available for wall mounting.
ISO KF vacuum systems employ components with metric interface dimensions which have been defined by the International Standards Organisation (ISO).This ensures a high degree of compatibility between components obtained from different sources.
EFT Vacuum ISO KF are compatible with Klein Flange (KF) types. Use ISO KF for tube sizes DN16 to DN50. Our standard range of KF flanges and fittings are manufactured from 304 (1.4301) stainless steel.
Maximum temperature for sustained use is 150°C. They are ideal for vacuum systems requiring regular assembly and disassembly. Each vacuum seal is made by compression of an O-ring on a centring ring between mating flanges. The seal is made in seconds
by finger-closure of a wing nut on the all-metal hinged aluminium clamp.
The ISO KF family of modular building block components includes all commonly used standard fittings, feedthroughs and accessories. Reducing flanges are available to connect different size components.
Mating flanges are offered to interface with pipe and other flange systems including LF and CF.
The generation of ultra high vacuum (UHV) makes great demands on the material and connections. Therefore the CF standard was created in the UHV technology (ISO 3669; enhancement ISO/TS 3669-2).
CF flanges are manufactured from circular blanks of stainless steel on CNC machines. Rotatable flanges are bipartite and consist of an inner part with the seal face and an outer part with the bolt holes.
CF flanges have an annular groove on the vacuum side for the reception of the gasket and a knife-edge.
EFT provides CF flanges and components of the dimensions DN10 to DN250 according to the pre-norm ISO/TS 3669-2. Please consider that individual standards of institutions are also available in the market. Please add the auxiliary dimensions
(DN25, DN50, DN75, DN125) in case of requests and offers of CF flanges and components. In addition please add the size and the number of required bolts and the necessary copper gasket for dimensions from DN250.
EFT follows the widely used convention of categorising different sizes of UHV flange by using a ‘DN’ specification.‘DN’ is the acronym of the French term ‘Diamètre nominal’ which translates as ‘Nominal bore’. The bore referred to is that of the tube that fits inside the designated flange. The bore is ‘nominal’because of the variation in tube wall thickness.
EFT 304 (1.4301) stainless steel tube is suitable for all high and ultrahigh vacuum applications. The material is priced per metre.
EFT is pleased to showcase this range of edge-welded bellows connectors for UHV.
These allow lateral movement, off-axis movement and vibration isolation.
Offered with four standard fittings Weldable CF or ISO KF and LF flanges, our bellows are manufactured to the highest standards of cleanliness for UHV applications. All bellows are constructed from stainless steel grade AM350 with connectors in SS304 material.
Special bellows assemblies and custom fabrications are also available on request.
EFT's ISO KF and ISO LF tube fittings are convenient building-block components. They offer great flexibility in the design and construction of high vacuum systems. All fittings are fabricated from 304 stainless steel drawn and welded vacuum tubing. Flanges do not need to be rotatable since they are completely symmetric. If desired, rotatable bolt ring assemblies can be retrofitted to existing claw-clamp style flanges to add bolt holes to ISO LF fittings. Reducers are used for a change in size of flanges within a single method of sealing, such as elastomer sealing of ISO KF and LF flanges

EFT hybrid adaptors provide a transition from one method of sealing to another. The hybrid feature of these adaptors is that the geometries at each end of any component are different.
This is more than a change in size within a particular sealing method.
They are available in most of the common interface transition pairs.
There are two major categories of adaptors: one combines pairs of standard vacuum flanges and the other combines standard fittings with flanges.
A frequent transition is from a metal seal flange to an O-ring sealed flange or fitting. Specifications are generally limited by the introduction of an O-ring seal. include at least one nonmetal seal and are therefore limited to high vacuum applications.
Refer to individual component sections for specifications. Reducers are a change in size within a particular flange sealing method, such as metal-seal to metal-seal. Reducers within a specific sealing method can be found in the fittings portion of each flange section.

EFT has developed a line of valve bodies that help address the needs of the Bioprocessing and Pharmaceutical industries for high quality, welded process systems.
By providing valve bodies with controlled sulfur SS316L stainless steel material and weld tangents long enough to accept the most common orbital weld heads in the industry, we have eliminated two of the most common concerns in valve-to-tube welding known today.
Automatic welding of 316L process components is greatly affected by the sulfur content of the mating process components. A disparity of sulfur content can result in reduced orbital weld quality and potentially incomplete fusion of the mating components. By controlling valve body sulfur content to the same chemistry as that required for ASME BPE fittings, welding problems due to material chemistry differences will be greatly reduced.
The EFT of valve bodies fully complies with the controlled sulfur requirements for chemical composition of SS316L material, set by the ASME Bioprocessing Equipment Standard 2002. By increasing the valve weld end tangent lengths to the values required for ASME BPE fittings, we made the valve body compatible with virtually any orbital weld head utilized in the industry. Special offset or narrow heads are no longer required to weld a valve into a process system.
Ideal for uninterrupted production in a broad range of hygiene-critical applications, Unique single seat valves are pneumatic seat valves used to shut off or change product flow.
EFT Seat valves are the extremely reliable all-rounders in the valve world. Our range includes on/off and control valves in stainless steel, with a stainless steel bonnet or a lightweight plastic actuator. They are available with a threaded or Tri-clamp connection, actuation is either pneumatically or motor-driven and they can be supplied with a flanged body. EFT Seat valves has very flexible design which meets sanitary requirements, and is mainly used in pipeline systems without contaminant or mixture. As a modern and widely-used valve, it is mainly used in the wine brewing, dairy, beverage, and pharmaceutical industries.
EFT Seat valves is remotely operated by means of compressed air. By controlling the relative position of valve plug, it makes the valve open or closed, or changes the flow direction of media. EFT Seat valves is equipped with our smart controller, which not only remote controls the single-seat valve, but can also perform real-time monitoring of the valve working conditions and timely feedback of signals. It can also be equipped with the position sensor only.

EFT is a pneumatic seat valve with sanitary and flexible design. Based on the mature single seat valve design platform, few and simple moving components make the valve reliable, and reduce the maintenance cost. FS3 tank bottom valve is used to close or open the pipe leading to the tank. It is widely used in brewing, dairy, beverage, and pharmaceutical industries.
EFT tank bottom valve is remote controlled by compressed air, which consists of one valve and one tank bottom flange. In order to reduce the abrasion of seal components, the compression to seal components is performed through touching between metals.
The modular design of the valve in connection with the radial seal to the tank now make it possible to close reliably against higher pressures than before. The reliability of the process is also enhanced: the balancer fitted in the closing direction prevents the double disk from closing too fast, thus reducing the risk of pressure hammers.
EFT took great care in making them industry appropriate, operator friendly and yet sturdy enough to withstand some pretty rough treatment. We made sure that our pneumatic actuators are not spring loaded, they all are machined from 304 Stainless Steel and are designed to withstand some dings and drops. All actuators have a position indicating shaft that extends when the valve is open (for visual confirmation of valve position) and contain as few o-rings and seals as possible which require very simple maintenance on an annual basis. Additionally, to prevent any galling, we machine all our actuator bodies out of 304 Stainless Steel, All EFT actuators meet 3A requirements and can withstand operating pressure of 250 psi and operating temperature of 135° C (or 275° F).
