Product Description
Product Overview
VCR Pneumatic Diaphragm Valve constructed from ultrahigh purity 316 EP stainless steel, designed for critical applications requiring leak-tight performance and contamination control.
Key Features
- Metal-to-metal sealing for leak-free service from vacuum to 10 bar (150 psig)
- Small internal volume with complete flow channel purge capability
- Fully wrapped valve seat design with superior anti-expansion and anti-pollution properties
- Nickel cobalt alloy diaphragm for enhanced durability and corrosion resistance
- Standard surface roughness Ra0.25μm (BA grade) or electropolished Ra0.13μm (EP grade)
- Helium test leakage rate < 1×10⁻⁹ std cm³/s
- Pneumatic actuator compatibility with working pressure 4.2-6.2 bar (60-90 psig)
- Extended service life up to 3 million cycles
