4001-P4 combination solenoid valve (1 inlet and 4 outlets, PTFE corrosion-resistant, specialized for corrosive gases and liquids)
Product Overview
The 4001-P4 combination solenoid valve is an integrated solenoid valve group designed specifically for corrosive gases and corrosive liquid media. The product adopts a structure of one common input port and four independent output ports, integrating four solenoid valves into the same valve body to achieve independent on-off control of multiple corrosive media. The core material of the valve body is selected from polytetrafluoroethylene (PTFE), which has excellent corrosion resistance and can withstand long-term corrosion from strong acids, alkalis, and various organic solvents without damage. Widely used in fields with strict requirements for corrosion resistance, such as chemical fluid control, pharmaceutical production, environmental water treatment, analytical instruments, experimental equipment, etc.
Core advantages
PTFE material, truly corrosion-resistant
The valve body and core components in contact with the medium are made of PTFE (polytetrafluoroethylene/plastic king) material. Unlike traditional metal solenoid valves, PTFE material can effectively prevent electrochemical corrosion and withstand long-term corrosion from concentrated sulfuric acid, concentrated hydrochloric acid, strong alkali, and various organic solvents without damage. The fluid medium only comes into contact with PTFE and specialized seals, achieving true corrosion-resistant isolation structurally.
1 in 4 out integrated design, multi-channel independent control
Adopting a structural layout of 1 common input port and 4 independent output ports, integrating 4 solenoid valves into the same valve body. Each solenoid valve is equipped with an independent coil, which can be opened separately or simultaneously to achieve independent on-off control of 4 outputs. Integrated design significantly saves installation space and simplifies pipeline layout.
Quick response and zero leakage guarantee
The direct acting working principle ensures that the valve responds quickly, sensitively, and reliably after being powered on. The combination of precision machining technology and high-quality sealing materials ensures zero leakage of valves in the closed state, especially suitable for safety control scenarios of toxic and corrosive media.
Low power consumption, long lifespan
Optimized electromagnetic coil design with low power consumption and minimal heat generation, suitable for long-term continuous operation. PTFE material and high-quality seals ensure that the valve maintains a long service life even under frequent switching conditions.
