Overview
The ASCO 8210B058 is a general-service, 2-way normally open solenoid valve from the world-renowned Series 8210 product line. This pilot-operated diaphragm valve features a brass body, NPT threaded ports, and reliable solenoid actuation for precise control of air, inert gas, water, and light oil in industrial automation, pneumatic systems, and commercial fluid control applications. The 8210B058 requires no minimum operating pressure and may be mounted in any direction, making it a flexible choice for system integrators and maintenance technicians.
Key Features
- 2-Way, Normally Open Design: Valve returns to open position on de-energization
- Pilot-Operated Diaphragm Action: Low coil power consumption and smooth, quiet operation
- Brass Body Construction: Lead-free brass with NBR seals for durability and low internal leakage
- 1-1/2″ Female Pipe Thread (FPT) Ports: 1-1/2 in. Female Threaded connections for straightforward installation
- High Flow Capacity: 1-1/4 FPT line, 1-1/8 in orifice, 15.0 Cv for efficient flow control
- No Minimum Operating Pressure: Requires no minimum operating pressure and may be mounted in any direction
- Durable Construction: 305 stainless steel core tube, 430F stainless steel plugnut, and resilient seals minimize leakage and extend service life
