Upgrade your rotary valves and your GC performance.
The PLSV drop-in replacement valves series is designed to improve trace GCs performance. To help all GC applications, our valves are backward compatible with third-party actuators.
Because third-party actuators failed to fulfill our requirements, we designed a high-quality, long-lasting actuator. It can do over 1,000,000 actuations at extreme temperatures (180 °C) and is built to survive as long as our GC valves. Upgrade to our CPA for a longer lifetime.
With its purging channels located between two adjacent valve channels and valve head purging pockets machined into the GC valve head, our PLSV’s unique, patent-pending design does away with leaks. The pockets connect the purging inlet and outlet through the channels, allowing purge gas to flow freely. Since the volume around the insert and in between ports is continuously removed, there are no more inboard/outboard and cross-port leaks.
Using finite element modeling (FEM) and real-life testing, we optimized the sealing lip size and shape. The result is a sealing surface area that’s 14% the size of a standard conical rotary GC valve, decreasing wear and tear and friction on the valve. What’s more, the insert material is specially treated by a proprietary process that improves the surface finish, hardness and creeping.
This latest innovation in diaphragm valve technology uses actuation gas to purge the valve’s inner volume
This durable, high-performance valve’s variable load mechanism releases the sealing pressure during actuation for an unprecedented lifetime
Our innovative, proprietary Purged Lip Sealing Valves offer all the simplicity of conical rotary valves – and last longer than diaphragm valves
