Pinch Valve
Pinch Valve
The market for Single-Use Systems (SUS) is rapidly increasing. More and more Bio-Pharmaceutical companies have adopted this relatively new concept. It is a method of better controlling the cleanliness of a production unit. Cleaning a conventional stainless steel vessel with all its components is a difficult task, not to mention the potential risk of cross-contamination from batch A to batch B, caused by absorption of some of the build-in components. Typically a SUS is built with new components, never exposed to any other drug before. These components are non-metallic and are usually cold sterilized by gamma irradiation. Steam sterilization is most of the time not possible because of the limited temperature resistance of some of the plastics used.
Pharma-Clamps
The Pharma-Clamp® is made from glass-filled nylon. This material is extremely strong and is stable during heat exposure and mechanical load. Traditional non-metallic clamps for single-use systems (SUS) are executed with a wing-nut. Operators who are putting Single-Use Systems together often complain about the number of wing nuts they have to assemble. It is time-consuming and can lead to repetitive strain injury (RSI).
Our Pharma-Clamp® is easy to use because there is only one way to close it, no adjustments are possible. Because of this over-compression and destruction of the gasket is prevented. The Pharma-Clamp® cannot be installed incorrectly, when closed it can take 10 bars of pressure without any problem.
The Pharma-Clamp® can be exposed to 50kGy Gamma radiation. It can be autoclaved and can withstand up to 150°C.
Available Sizes
- DIN32676 A, B, C same TC diameters
- 1/2″ through 6″ (TC 25 -TC 167)
Available Compound
CMD-1057 Nylon Glass Filled
Pinch Valve
The Pinch valve is made from the same glass-filled nylon as our Pharma-Clamp®. This material is extremely strong and is stable during heat exposure and mechanical load. The pinch valve has the same closing device as the Pharma Clamp®. Both have a locking device preventing unwanted opening during storage or transportation. A tie-wrap can easily be installed.
The Pinch Valve can be exposed to 50kGy Gamma irradiation. It can be autoclaved and can withstand up to 150°C.
Available Sizes
- Minimum tubing wall thickness is 2,40 mm maximum is 3,40 mm
- CMD-1057 Nylon Glass Filled
Pressure Gauge
This pressure gauge was developed specifically for Single-Use applications. It was designed so operators could see that the system was pressurized. The gauge indicates pressure. It is a mechanical device with low accuracy (±15%). The housing is filled with liquid silicone oil, so we recommend us a Gauge Guard Isolator gasket to prevent potential system contamination, in case of a gauge membrane rupture.
Available Sizes
- 3/4″ MINI TC connection
- 1″ -1.5″ TC connection
Available Compound
- CMD-1028 PTFE (non gamma sterilization)
- CMD-XXXX PP (under development)
