Product Description
The 4001-P6 two-way solenoid valve combination valve is a high-performance solenoid valve product developed specifically for precise on-off control of corrosive gases and liquid media. The product adopts PTFE polytetrafluoroethylene all plastic valve body material, with a 6-inlet and 1-outlet channel structure, and each channel is independently controlled by electromagnetic control, achieving selective introduction or centralized convergence of multiple media. Featuring three core characteristics of zero pressure differential start-up, zero leakage sealing, and excellent corrosion resistance, it provides highly reliable solutions for harsh industrial fluid control scenarios.
PTFE material, resistant to almost all strongly corrosive media
The valve body and flow channel body are made of PTFE polytetrafluoroethylene material, which has excellent chemical inertness and can withstand strong acids (such as sulfuric acid, nitric acid, hydrochloric acid), strong alkalis, organic solvents, and various corrosive gases. Different from the metal valve body+coating scheme, the all PTFE structure has no risk of coating peeling, eliminating the possibility of medium contact with metal parts from the root, ensuring the purity of the medium and the service life of the valve body under long-term use.
Zero pressure differential start, suitable for ultra-low pressure/vacuum conditions
The solenoid valve adopts a zero pressure difference design, and can be opened and closed normally without establishing a minimum working pressure difference. Specially suitable for fluid control scenarios in low-pressure liquid/gas supply systems, gravity flow pipelines, negative pressure suction, and vacuum environments, solving the industry pain point of traditional pilot operated solenoid valves being unable to operate under low-pressure conditions.
Zero leakage sealing ensures safety and environmental protection
Adopting high-performance sealing structure design and precision machining technology, ensuring that the valve body reaches zero leakage level in both open and closed states. Effectively preventing the leakage of corrosive media, ensuring personnel safety, equipment cleanliness, and environmental compliance, while avoiding media contamination between multiple channels, meeting high-purity process requirements.
6-in-1-out architecture, flexible implementation of multi-channel gating
The standard product is designed with 6 independent inlets and 1 centralized outlet. Each channel can be independently controlled for on/off, enabling on-demand selection, sequential switching, or mixing of 6 different media or 6 independent sources. Suitable for applications such as multi-media switching supply, multi station circulating sampling, and centralized discharge of multiple waste liquids.
Support non-standard customization from 2 in 1 out to 12 in 1 out
In addition to the standard 6-in-1, our company supports non-standard customization of any multi-channel combination such as 2-in-1 out, 3-in-1 out, 4-in-1 out... 12 in-1 out, etc. We also support normally open, normally closed, and hybrid valve position configurations to flexibly match different process routes and equipment space layout requirements.
