VNV Series Pressure Gas Needle Valve>> Compact design, stable pressure control
The VIGOUR VNV Series needle valves are engineered for high-precision flow control in demanding industrial and laboratory applications. Designed with performance and durability in mind, these valves offer reliable operation under pressures up to 345 bar and across a wide temperature range from -54°C to +232°C.
Key Features:
- Live-Loaded Packing System: Ensures consistent sealing and reduces maintenance needs.
- Multiple Stem Options: Choose from Vee, regulating, or soft-seat stems to match your application requirements.
- Compact & Versatile Design: Available in straight, angle, and cross flow patterns with panel-mounting capability.
- Robust Materials: Constructed with 316 stainless steel body and PCTFE seating for superior chemical and thermal resistance.
- Low Leak Rate: Certified leak rate of 0.1 cofmin for safe and efficient performance.
Typical Applications:
- Component Testing
- Calibration Systems
- Laboratory Pressure Control
- High-Pressure Sampling Systems
- Service and Test Equipment
