New valves meet medical requirements

New valves meet medical requirements A new development by ASCO Scientific greatly reduces the possibility of seat leakage in solenoid valves due to the action of particulate matter. The development is an inert isolation valve (series 462) that uses a “Resilient-Seal” against the valve seat. The series 462 uses a soft Kalrez1 disc inserted into a PTFE diaphragm. The PTFE diaphragm provides the rigid structure that isolates the fluid from the solenoid components while the Kalrez1 disc provides a very tight seal on the valve seat. Since Kalrez1 is an elastomer, it has excellent sealing characteristics. It is also a very inert material; therefore it is compatible with the majority of solvents and reagents used in analytical instruments. In addition, the resilient nature of the Kalrez1 disc means that particulate matter does not easily scratch it, as is the case with a complete PTFE diaphragm.
