AUTOMATIC SWITCHOVER system
High performance analytical instruments require high purity gas supplies. Our ultra high purity switchover system and valves series are especially designed for trace impurities analytical devices.
The LDASS (automatic switchover system) series is specially designed to provide continuous gas flow from two high pressure sources. They are complete high purity changeover system which combines the changeover regulator and a line regulator into a compact wall mount system for ultra high purity and specialty gases.
Diffusion-resistant metal diaphragm seal ensures gas purity and integrity. Mounting bracket is standard and internal parts are stainless steel 316L and suitable for cylinder gas, bulk gasline, mixed gas or any other type of gaseous mixtures.
