 | TYPE F3 STANDARD and F3 W
Threeway-Plug-Valves vertical and horinzontal
Nearly all cases of application can be solved with the AZ-threeway-plug-valves type F-3-Standard with third vertical flange. Only in rare cases type F-3-W with third horizontal flange has to be used. We always recommend, whenever possible, to use type F3-Standard with third vertical flange. With this type of valve the service life of the PTFE-sleeve is much higher. AZ-threeway-plug-valves are available in a large range of materials and material combinations (valve body and plug),e.g. carbon steel, stainless steel, special alloys etc.
Further advantages of the AZ-threeway-plug-valves are the possibility of mounting actuators. Adjusting nuts are freely accessible, also when actuators are mounted. A speciality of AZ-threeway-valves: The position of the plug can be seen by a short glance at the position indicator.- Cavity free

 | Screwed-Plug Valves
1 with threaded connection ¼" to 1"
AZ screwed valves have the same special advantages as all AZ plug valves.vThe construction of these screwed valves distinguishes itself through very high precision of the supporting sleeves pressed into the body. Without touching the conical plug the supporting sleeves adjust themselves exactly to the form of the plug. This excludes distorsion of the PTFE-sleeve in the valve body and PTFE cold flow. Special alloys like: Titanium, Nickel, Monel, Tantal, Hastelloy on request. AZ Screwed Valves are available as 2, 3, 4 and 5 way valves, with male and female thread. Special connections on request. On request we can also supply the type "MB" with AZ round lever.- Vacuum tight

AZ-Crossover-Valve-Combination - the logical consequence of application of AZ-valves!
The extent of application is logically and substantially enlarged by the combination of AZ-valves. A lot of problems can be solved favorably by application of AZ-crossover-valve-combinations. AZ-crossover-valve-combinations, installed in filter and reactor cycles make a connection between two filters without any problems without closing during the phase of switching. Therefore it is possible to change the filter easily without stopping the process. In the same way it is easy to change safety valves by application of AZ-crossover-valve-combinations for reactor cycles. All AZ-valves are combinable, also different nominal sizes, therefore nearly unlimited possibilities of application. AZ-crossover-valve-combinations are available as hand-operated, gear-operated as well as with actuators.- All types of AZ-valves combinable
- For cooling and heating cycles
- For pump cycles
- For safety-valves
- For filter cycles
- For reactor cycles
- Available hand-operated, gear-operated and with actuators

 | TYPE SAVA
Special cross-over combinations for Safety (Relief) valves
The proven 3-way plug valve, type F3-EXTRA with full round bore, has been further developed for the change over of safety valves, in close cooperation with the Engineering Department of a big chemical concern and TÜV-Southwest. The basic principle of the safety valve exists therein, that dependent on the construction, a least cross section (A) is guaranteed during the cross-over phase from safety valve I to safety valve II. Therefore a minimal flow (protection of the vessel) is always given.- Full-flow, round bore
- Cavity free (which means: accretion at valve seat impossible)
- 100% tight shut-off even after a long stationary period (DIN 3230 T3 Leakrate 1)
- Harmless to human being and environment by disassembling one of the safety valves
- Fully transflow during the whole cross-over action
- Operation errors impossible because of position indication
- Safe backflow of blow off capacity
- Reasonable priced combination; different sizes uncomplicated linkable (reducers not necessary)
- TÜV approved

 | TYPE SAMPLING
Sampling System
The development of the AZ-Sampling system is based on decades of experience in the production of AZ Plug Valves in cavity free design with self lubricating, maintenance free PTFE sleeve, consequently the logical result of the practice-based application of these valves. The AZ-Sampling system can be installed directly into the process pipe or in a bypass. During the production process, the plug of the sampling system is in open position, which means that the balance pipe and the sampling port are closed. For drawing a sample the plug must be turned 90° by means of the lever. Because of the positive overlap, the intersection of the process pipe is guaranteed. During the switchover a specific defined sample quantity (30-50 ml or more) is contained in the plug. After reaching the 90° lever position, which is exactly restricted by limit stops on the cover, the sample quantity is transferred through the process needle into the sample container. The air in the bottle, which can be mixed with gas or steam, can escape through the balance pipe into the closed system.- Closed system
- Cavity free
- Spilling eliminated and contamination free (TA Luft)
- Specific defined sample quantity
- Pressure free sampling (positive overlap)
- Simple and safe operation
- Absolutely tight
- Representative sample by extraction from the process of Bypass pipe
- Vertical and horizontal installation possible
- Pneumatic or electric actuation possible

 | TYPE VARIO
Sampling System
Due to the integrated stainless steel sample container it is now possible to take “bigger” sample quantities. The quantities are exactly defined by the size of the sample container. The type “VARIO” is available in 2 different designs (VARIO and VARIO G2) and both of these can be provided with 2 different bottle systems.- Closed system
- Cavity free
- Free definable sample quantity
- Pressure free sampling (positive overlap)
- Spilling eliminated and contamination free
- Simple and safe operation
- Absolutely tight
- Compact design

|
 | TYPE CONTIFLOW-TRF
Sampling System
For the first time - with the “CONTIFLOW-TRF” - a sampling system has been constructed which is piggable and absolutely cavity free. This was made possible because of the special design of the fully PFA- or PTFE lined plug. Furthermore this construction allows a representative extraction from the process pipe without interruption of flow.- Cavity free
- Piggable
- Simple and foolsafe handling
- Pressureless sampling
- No flow interruption
- Defined sample quantity
