REDHAT

REDHAT normally open (NO) solenoid valves allow flow when the coil is de-energized and stop flow when energized. Normally closed (NC) valves stop flow when de-energized and allow flow when energized. Both configurations are available in 2-way/2-position designs. For example, the REDHAT 8210G014 is a normally open valve with a 1 in pipe size and 120V AC coil, while the EF8210G004 is a normally closed valve with similar specifications. The choice depends on the fail-safe position required for your process. NO valves are often used where flow must continue during a power failure, while NC valves are used where flow must stop.

REDHAT solenoid valves with NBR seals are compatible with air, inert gases, light oil, and water. This is indicated in the specifications for models such as the EF8210G004 and the 8262H020LF. For other media, alternative seal materials may be available. It is important to verify chemical compatibility and temperature ranges before installation. The valves are designed for on/off control in industrial piping systems, and the high-flow ratings make them suitable for applications requiring rapid response. Always consult the specific datasheet for the valve model to confirm compatibility with your process fluid.

REDHAT solenoid valves are available with a range of AC and DC coil voltages. Common options include 110V AC, 120V AC, 220V AC, 240V AC, and 100–240V AC/DC. For example, the SU8210P094 100-240 valve operates on 100 to 240V AC/DC, while the 8262H020LF is rated for 240V AC (and 220V AC at 50 Hz). Wattages vary by model, from 1.5 W to 16.1 W. When selecting a valve, ensure the coil voltage matches your available power supply and that the wattage is within your control circuit capacity. Watertight coil enclosures are available for damp environments.

REDHAT gas shut-off valve bodies are used to control the flow of gaseous media in industrial gas trains and piping systems. They are 2-way/2-position, normally closed valves with spring-return actuators. Models such as the 8158A218X1X0100 feature a die-cast aluminum body, linear trim, and a strainer. These valve bodies are typically part of a safety shut-off system, where the spring-return actuator ensures the valve closes if power is lost. They are suitable for natural gas, propane, and other industrial gases. The valve bodies require a compatible solenoid coil or actuator to operate, which may be ordered separately.

Selection depends on several factors: pipe size, flow coefficient (Cv), media type, pressure, temperature, voltage, and fail-safe position. REDHAT valves are available in pipe sizes from 1/4 in to 1 in, with high-flow options. Determine whether you need normally open or normally closed operation. Check the seal material compatibility with your media—NBR is standard for air, inert gases, light oil, and water. Verify the coil voltage and wattage match your power supply. For gas applications, consider the gas shut-off valve bodies with spring-return actuators. 3G Electric provides datasheets and application support to assist with selection. Always confirm the pressure and temperature ratings for the specific model.

REDHAT model numbers typically indicate the valve series, configuration, and options. For example, the 8210 series is a line of 2-way solenoid valves. The suffix G014 may denote a specific pipe size, voltage, and seal material. The EF prefix often indicates a high-flow version. The 8262 series is another common family. While the exact coding system is proprietary, the model number can be cross-referenced with the datasheet to confirm specifications. When ordering, provide the full model number to ensure you receive the correct valve. 3G Electric lists these model numbers to help buyers identify the exact part.
