FSY7000 series bottom plate piping type(7140 Series)
Detailed description
The SMCSY series 5-way solenoid valve, direct piping type (single unit), is a high-efficiency pneumatic control component designed for stand-alone equipment and small-scale automation scenarios. Its core advantage is that it does not require a base plate and can be installed directly by pipe. It combines compact structure, quick assembly, high reliability and low power consumption, making it a perfect fit for pneumatic circuits with limited space and a small number of valves. It is the preferred control component for small-scale automation systems.
Core Features
1. Easy installation, no additional accessories required
The valve body features a full set of interfaces: P (inlet), R (exhaust), and A/B (operating port). It requires no additional mounting base and can be directly installed via air hoses or threaded connectors for independent use. It also supports parallel installation of multiple valves or integration with a 3-way valve, offering high installation flexibility and significantly reducing assembly time and space costs.
2. High reliability and long-term stable operation
With an IP65 dustproof and waterproof rating and a flexible soft-seal structure, it effectively resists dust and moisture intrusion, making it suitable for various industrial environments. The oil-free lubrication design reduces maintenance costs, and the commutation life can reach tens of millions of cycles, ensuring long-term stable operation and reducing equipment failure rate.
3. Energy-efficient and easy to operate
The standard model consumes only 0.4W, while the model with a power-saving circuit consumes as little as 0.1W, significantly reducing energy consumption; it also boasts a fast response time.(≤19~30ms, 0.5MPa operating condition), with a maximum operating frequency of 5Hz, suitable for high-frequency operating scenarios. It comes standard with a non-locking push-type manual operation button, allowing for quick manual switching of the valve position during commissioning. Some models support push-to-lock for even more convenient operation.
Electrical and control characteristics
• Control type: Supports single control (reset type) and dual control (memory/retention type) to meet different control needs.
• Power supply voltage: Mainstream DC12V and DC24V, optional AC100/110/220V, compatible with general industrial power supplies.
• Safety Features: Standard LED status indicator light clearly displays valve position; built-in overvoltage protection circuit (with "Z" suffix) effectively prevents coil burnout, enhancing operational safety.
• Wiring methods: Supports multiple wiring methods such as L-type sockets and direct cable output (G-type), making wiring convenient and adaptable to different installation scenarios.
Applicable Scenarios
The SY series 5-way solenoid valve, with its direct piping type, is widely used in various small-scale automation scenarios due to its compact size, quick installation, and flexibility, and is especially suitable for:
• Standalone equipment and small automated workstations (such as small assembly machines and testing equipment)
• Pneumatic control circuits with limited installation space and a small number of valves
• Field applications requiring rapid installation, commissioning, or frequent valve replacement
• Small pneumatic systems with low energy consumption requirements and high reliability
