Back New Product Launch: FITOK Economic Diaphragm Valves
Introduction
DE series economic diaphragm valves are typical products for ultra high purity gas fluid systems. Reliability and economy are achieved by reducing the number of components, optimizing machining methods and mass production, while maintaining the same basic performance by using the same materials, cleaning and packaging processes as the other series of FITOK diaphragm valves. FITOK's advance manufacturing processes and stringent quality control ensure the products meet the application needs of ultra high purity gas fluid systems for the semiconductor industry.
Features
- Minimum particle generation and dead space
- Cobalt alloy diaphragm with high strength and corrosion resistance to ensure long cycle life
- No springs or threads in wetted areas improves cleanliness
