MAC solenoid valves Series 34

MAC solenoid valves Series 34 represent high reliability and performance in industrial automation and are designed for applications requiring fast response and stable airflow control. The following is a detailed analysis of its core features and technical details, as well as a list of typical models and application scenarios:

Product Positioning and Core Design

The 34 Series is a direct solenoid-operated, 3-way, 10mm poppet valve, with a patented design that realizes a high flow rate in a small package. Its core advantages include:

Direct Actuation Technology:

No pilot air line is required, the solenoid acts directly on the spool, resulting in an extremely fast response time (3.4 ms on, 1.5 ms off). This feature allows it to excel in high-frequency commutation scenarios such as packaging machinery and tire curing.

Counterbalanced Poppet Construction: The symmetrical design of the

spool automatically compensates for fluctuations in air supply pressure (vacuum to 120 psi), ensuring stable commutation under varying operating conditions. The valve maintains precise flow control even when source pressure varies.

High flow capacity:

10mm diameter with optimized flow path design, the maximum flow coefficient (Cv) of 0.12, far more than the same size competitors. For example, in the automotive parts assembly line, it can quickly drive the cylinder to complete high-precision gripping action.
