4001-F2 High-Pressure Combined Solenoid Valve (1-in, 2-out) - Stainless Steel 316 · Independent Control · Zero Leakage · Customizable Product Overview The 4001-F2 High-Pressure Combined Solenoid Valve is a 1-in, 2-out (diverging type) combined solenoid valve specifically designed for high-pressure fluid systems. The product features a stainless steel 316 valve body and integrates dual solenoid coils for independent control of the two output channels. The working medium pressure covers 0–80 kg (0–8 MPa), making it suitable for diverging and directional control of water, gas, oil, steam, and various corrosive media.
This product integrates functions that traditionally require two single valves into one, offering advantages such as smaller space occupation, easier installation, and lower cost compared to installing two solenoid valves separately. The valve body adopts an integrated and compact design, featuring a reliable structure and convenient installation.
Technical Parameters: Item | Specification | Product Model | 4001-F2 | Control Mode | 1-in-2-out (diverter type) | Valve Body Material | Stainless Steel 316 / 316L | Working Medium Pressure | 0 – 80 kg (0 – 8 MPa) | Applicable Medium | Water, gas, oil, steam, corrosive fluids, etc. | Temperature | Customizable (-40℃ to +350℃) | Power Supply Voltage | DC12V, DC24V, AC24V, AC110V, AC220V, AC380V, etc. | Connection Mode | Threaded (female/male) | Leakage | Zero | Valve Body Type | Combined / Integrated Valve Group | Wiring Method | Plastic-sealed box plug / Iron-covered lead | Protection Level | Customizable | Note: The above parameters are standard configurations and can be customized according to customer needs.
The working principle of the 4001-F2 high-pressure combination solenoid valve is a 1-in-2-out control mode, with two sets of independent solenoid coils built-in, which control two output channels respectively:
When the first circuit coil is energized: the inlet (P) → outlet A (first circuit) is opened, and outlet B (second circuit) is closed
When the first circuit coil is powered off: the inlet (P) → outlet A (first circuit) is closed, and outlet B (second circuit) is opened
The two outputs are controlled independently and do not interfere with each other. The product adopts a pilot-operated piston structure, utilizing medium pressure to drive the main valve spool, enabling sensitive and reliable directional and flow control even under high-pressure conditions.
Product Advantages:

* Integrated Design: Dual valves are integrated into one, saving installation space and reducing pipeline complexity.
* Independent Control: Two outputs can be controlled independently to meet diverse flow distribution needs.
* High-Pressure Capacity: Operating pressure ranges from 0 to 80 kg, covering a wide range of working conditions from low to high pressure.
* Corrosion Resistance: Stainless steel 316 valve body, suitable for corrosive medium environments.
* Zero Leakage: Precise sealing design ensures system safety and reliability.
* Flexible Customization: Voltage, interface, explosion-proof rating, etc. can be customized as needed.

Application Fields: The 4001-F2 high-pressure combination solenoid valve is widely used in various industrial automation systems that require high-pressure medium flow distribution and directional control
Petrochemical industry: Diverging and reversing control of corrosive media
Water treatment system: Flow distribution and switching of fluid pipelines
Power equipment: On-off control of cooling water and sealing water
