<sub>Wafer Type Check Valve SR, ZRK, ZRD
Whether as a standard product or as a custom order: RITAG wafer type check valves are available in any nominal diameter, pressure level and material for your processes.

The development and manufacture of our high-quality valves are in compliance with all international standards and regulations.</sub>

• Robust and reliable

• For horizontal pipelines and vertikal pipelines  

• Flanged body

• Design according to DIN and ASME

• For liquids, gases and vapours

The Type BA bottom valve cone opens into the container. Only the spindle remains in the housing. In addition to the drive power, the container interior pressure helps in sealing the valve tightly.

Type BAS cone valves open into the valve. This has the advantage, in the case of containers with agitators, that the agitator is able to operate all the way to the wall. The container interior pressure acts here against the cone.

Type BV piston valves as a rule open into the valve and therefore keep the entire cross section of the housing open. Furthermore, it is possible to use the piston to break through a crust and then open into the valve.

If the container is covered with soil it is difficult to install a valve under the container. Therefore, for Type BVS valves, the valve had to be placed into the tank. Weights make sure that the valve is closed securely in case the controlling air pressure should fail.

<sub>RITAG Type EPOS® – Easy POsitive Sampling
The RITAG EPOS® sampling systems are of a modular design and offer a wide range of combination options for all requirements.

The EPOS® basic unit consists of 2 modules: the control unit and the housing in five variants. All EPOS® control units – hand wheel, "dead-man's" lever and pneumatic operation – are all equipped with spring-to-close hand wheel and close after each operation. Strong spring assemblies make sure of this; they cope with these tasks perfectly in conjunction with the standard components. All operating units are combinable with all housing variants. Furthermore, the system can be combined with accessories like adapters, containment tanks, piston injector, heating jacket, laboratory bottles in various sizes and much more.

When the medium itself constitutes a seizable risk for the operator and / or the environment, or if the medium itself has to be protected from outside influences (e.g. oxygen injection), the EPOS® cabinet system and the EPOS® piston injector are to be recommended.

The EPOS® cabinet system has a special locking mechanism: the cabinet will stay locked during the sampling process and the bottle is sealed from the outside. After opening the door, the bottle can be safely removed. In addition, it is possible to rinse the bottle, as well as the cabinet system with nitrogen before any sampling takes place.

The large EPOS® piston injector has self-locking threading, which makes a rebound of the piston practically impossible in the injector under pressure. The large EPOS® piston injector closes itself off by means of a spring-to-close hand wheel after sampling has been completed.</sub>

_{The RITAG cone and piston valves are exceptionally well suited for sampling from containers.
The RITAG Type BAP sampling valves has been designed as the cost efficient container sampling option from DN 25 on. In this case the cone opens into the container.
A sampling valve from the product range Type BVP operates with a piston. The entire line diameter can be cleared by the return of the piston. Good sample dosing is made possible with a crank or a hand wheel, in contrast to a ball valve.}

_{RITAG Type HYPOS 100 check valve was the first product developed by our team of engineers for the Clean Service industry sector. The former EHEDG certificate verifieed the proper CIP functionality of the valve.
Based on this experience with the prototype we designed check valves, sampling valves and bottom valves; their distinguishing characteristics are no-dead-space and nearly no gaps, which makes them especially secure and reliable during cleaning.}
