Product Description
ASCO 210 Series 2 Way Brass Solenoid Valve Pilot Operated Normally Closed Water Air Gas Fluid Control
Product Overview

The ASCO Series 210 (also known as the 8210 series) is a line of high-flow, pilot-operated solenoid valves designed for general service. Featuring a robust forged brass body and advanced hung diaphragm technology, these valves provide reliable on-off control for a wide variety of industrial applications involving air, inert gas, water, and light oil. It is the global standard for performance and longevity in fluid automation.

Key Features
  • High Flow Capacity: Optimized internal design allows for maximum flow rates with minimal pressure drop
  • Durable Construction: Forged brass body and stainless steel internal parts ensure excellent corrosion resistance
  • Zero Minimum Pressure: Available versions that operate from zero differential pressure, ideal for low-pressure systems
  • Reliable Sealing: High-quality NBR (standard) or FKM seals provide leak-proof performance and long service life
  • Compact Design: Space-saving architecture allows for easy installation in tight industrial cabinets and manifolds
  • Global Compatibility: Available in multiple AC and DC voltages to meet international electrical standards

Frequently Asked Questions
Q: Can this valve be used for steam applications?

A: The standard 210 series is for air, water, and oil. For steam, we recommend the ASCO 8221 or 8222 series specifically designed for high temperatures.

Q: Is a minimum pressure required to operate?

A: Most 210 series valves are pilot-operated and require a minimum differential pressure (usually 5 psi). However, we offer hung diaphragm versions that operate at zero pressure.

Q: Are replacement coils available separately?

A: Yes, we provide genuine ASCO replacement coils (e.g., 400425-117) for all Series 210 valves.

Q: Do you offer NPT or G threads?

A: We provide both NPT (standard for US) and G/BSPP (standard for Europe/Asia) thread options. Please specify when ordering.
