MPD Series Solenoid Pinch Valve

The MPD Series Solenoid Pinch Valve is a magnetic-latching, normally-closed micro pinch valve with zero holding-state power consumption. It features a fully isolated fluid path design, supports panel mounting and an optional position feedback sensor, making it ideal for fluid on/off control in biochemical analyzers, IVD instruments, and microfluidic laboratory equipment.

METICULAB MPD Series Solenoid Pinch Valve – Zero-Power Holding, Normally Closed, Tube OD 1.6–12.7 mm

Brand: METICULAB ｜ Series: MPD ｜ Type: Latching Solenoid Pinch Valve ｜ Origin: China

MPD Series Solenoid Pinch Valve

METICULAB MPD Series is a latching-type miniature normally-closed pinch valve, specifically designed for laboratory fluid equipment and in-vitro diagnostic (IVD) instrument integration. The valve adopts a pulse-driven latching mechanism — no continuous power is required to maintain the open or closed state; power is consumed only at the moment of switching. This significantly reduces the overall power consumption of the host instrument and makes it ideal for built-in compact analytical devices.

The valve features a fully isolated flow path: the fluid medium flows only inside the tubing, while the valve body and metal magnetic circuit components never contact reagents or samples. There is no valve core structure, eliminating media crystallization and cross-contamination. The compact body supports panel-mount installation, occupying minimal internal space. An optional position feedback sensor is available to output real-time open/close status for system monitoring and logic control. The tubing is a consumable item — maintenance only requires tube replacement, with no need to disassemble or clean the valve body.

The MPD Series is compatible with various tubing specifications. Different tube materials can be selected based on media characteristics, covering corrosive reagents, biological samples, aqueous solutions and other low-pressure fluid transfer scenarios. The factory default is normally closed — the tube is clamped to cut off the flow path when de-energized. A pulse signal opens the valve, ensuring safe and reliable operation.

• Non-standard custom solutions are available based on customer equipment structure requirements.

❓ Frequently Asked Questions (FAQ)

Q: What does "zero-power holding" mean?
A: The MPD series uses a latching solenoid. Once the valve switches to open or closed, no continuous power is needed to maintain that state. Power is consumed only during the switching pulse, greatly reducing the host instrument's energy consumption.

Q: Is the valve normally open or normally closed?
A: The MPD series is normally closed (NC) by default. When de-energized, the tube is clamped and the flow path is shut off. A pulse signal opens the valve.

Q: What tube sizes are supported?
A: Four models cover tube OD from 1.6 mm to 12.7 mm: MPD-04 (1.6–3.2 mm), MPD-06 (3.2–6.4 mm), MPD-08 (6.4–9.6 mm), MPD-10 (9.6–12.7 mm).

Q: Can I get a position feedback sensor?
A: Yes. An optional position feedback sensor is available to output real-time valve open/close status.

Q: Do you offer OEM / ODM customization?
A: Yes. We support OEM / ODM customization based on customer drawings and equipment structure requirements.

Q: What is the lead time?
A: Standard models are usually available from stock. Custom orders typically take 15–30 working days depending on complexity and quantity.
