Innovative Our Valves
Purged lip sealing valve (PLSV)
Our innovative, proprietary Purged Lip Sealing Valves offer all the simplicity of conical rotary valves – and last longer than diaphragm valves
- Unique purge technology eliminates leaks
- Long lifetime: Over 3 million actuations
- Constant pressure drop
- No dead volume
Purged lip sealing valve Drop-in replacement
Our innovative, proprietary Purged Lip Sealing Valves offer all the simplicity of conical rotary valves – and last longer than diaphragm valves
- Unique purge technology eliminates leaks
- Long lifetime: Over 3 million actuations
- Constant pressure drop
- No dead volume
Purged pulse diaphragm valve (PPDV)
This latest innovation in diaphragm valve technology uses actuation gas to purge the valve’s inner volume
- Static purge design reduces operation and integration costs
- New plunger design increases lifetime
- Long-term storage pressure relief
- Can be retrofit to replace any diaphragm valve
HPLC Wear proof valve
This durable, high-performance valve’s variable load mechanism releases the sealing pressure during actuation for an unprecedented lifetime
- Up to 5x longer lifetime than other valves technology
- Better performance and quality
- Variable sealing pressure technology
- No dead volume
Wear-proof actuation mechanism
What makes our GC and HPLC valves so unique is that they use a revolutionary, frictionless actuation mechanism – a proprietary technology that allows the force profile to release pressure during actuation. The result is that high pressure can be used for sealing and a lower pressure can be used during rotation, reducing the insert’s wear and increasing its lifetime.
Key features:
- Field-adjustable sealing force allows valve to be tuned for each application, avoiding excessive sealing force
- Extra-long lifetime: lasts well over 2 million actuations
- Smooth rotation, no gear-style CAM
