ASCO Red Hat 8210B057 1″ 110/120V 125 PSI Brass Solenoid Valve

The ASCO Red Hat 8210B057 is a 2-way, typically open, pilot-operated general service solenoid valve that can be used to reliably turn on and off air, water, and light oil in industrial systems. The 1″ NPT brass body, 110/120V AC coil, and 0–125 PSI rating make it a great high-flow, long-lasting valve for OEMs, maintenance, and replacement. The Red Hat general service Series 8210 family includes this ASCO 8210B057 valve. It is often used to manage high flow in circuits for compressed air, process water, and light oil. It has a diaphragm design that is operated by a pilot and has a flow path that is generally open. This means that when the power is off, the flow is full, and when the power is on, the flow is positive shutdown. The valve has a tough brass body and NBR (Buna-N) elastomer seals, so it can last a long time in tough places including industrial facilities, utilities, and commercial equipment. The 20 W Class F coil and Red Hat inclosure can work continuously and in a wide range of temperatures.   Asco 8210b057 Solenoid Valve Specifications Parameter Value Model ASCO 8210B057 Red Hat Series 8210 general service solenoid valve  Valve type 2‑way, 2‑position, pilot‑operated, normally open  Function On/off control for air, inert gas, water, and light oil  Pipe size 1″ NPT female (inlet and outlet)  Orifice size 1″ full port  Flow coefficient (Cv) 13 Cv high‑flow capacity  Body material Brass  Internal wetted materials Brass, stainless steel disc‑holder, NBR (Buna‑N) seals  Seal / seat material NBR (Nitrile/Buna‑N) elastomer  Media Clean air, inert gas, water, light oil  Pressure range 0 to 125 PSI for air/inert gas, water, and light oil  Max fluid temperature Up to 180 °F (82 °C)  Supply voltage 120 VAC 60 Hz / 110 VAC 50 Hz coil (110/120 V AC)  Coil wattage 20 W, Class F insulation  Enclosure rating Red Hat enclosure, NEMA 1/2/3/3S/4/4X; watertight, dust‑tight, corrosion‑resistant (coil‑dependent)  Min differential pressure 0 PSI (zero‑differential operation)  Applications General purpose on/off service for clean water, air systems, and light oil circuits    Features: 1) Design for high performance High-flow 1″ porting with Cv 13 for smooth flow in medium- to large-bore lines, which helps keep pressure from dropping too much in process circuits. The normally open setting allows for fail-open behaviour (flow when de-energized), which is perfect for venting, dumping, or other situations where flow is needed when power goes out. The pilot-operated diaphragm architecture allows for zero-differential operation from 0 to 125 PSI, making it easier to design systems where line pressure changes. 2) Building and strength The brass body and stainless steel disc holder make this product very sturdy and resistant to corrosion in industrial settings. NBR (Buna-N) seats and seals work well with air, water, and light oil over a wide range of temperatures. The 20 W Class F Red Hat coil is designed for continuous duty, so it works well even when it is cycled often. 3) Electrical and environmental: The dual-frequency coil (110 V 50 Hz / 120 V 60 Hz) makes it easier to store and repair parts in installations around the world. The Red Hat inclosure comes in NEMA 1/2/3/3S/4/4X variants and protects against dust, water, and corrosion in tough places. Quick-acting solenoid response allows automated systems and PLC-driven processes to turn on and off quickly. 4) Advantages of using As a general service valve, it is used a lot in industrial air compressors, power washing systems, industrial water control, and pump skids. This standard, industry-proven form factor is good for OEM machinery, utilities, and maintenance replacement, which cuts down on downtime. Works with a lot of ASCO Red Hat mounting and conduit accessories, making it easier to add to existing panels and manifolds.   Usage in Industry: Control for general service on and off for clean water distribution loops, process water skids, and utility water lines with a pressure of up to 125 PSI. Control of air and inert gas in compressed air headers, manifolds, and feed lines for pneumatic equipment that need to fail open. Light oil service in lubrication circuits, low-viscosity oil transfer, and hydraulic pilot lines within the rated pressure and temperature range. Venting and drain/dump chores where full flow is needed most of the time and shutdown only happens when the system is powered on. OEM equipment, skids, and panel-mounted assemblies that need a small, high-flow, AC-powered general-purpose solenoid valve with a 1″ NPT.
