Humphrey Balanced Solenoid Valve Series

Humphrey Balanced Solenoid Valve: Ongeëvenaarde Druk-onafhankelijke Controle

The Humphrey Balanced Solenoid Valve series represents the top of pneumatic innovation. Thanks to the unique balanced poppet design, these valves operate completely independently of pressure fluctuations. Inacom supplies this versatile series to engineers who need a constant response time and reliability, whether they work with vacuum or high pressure.

Why choose the balanced design?

Unlike conventional valves, where system pressure can affect armature operation, the Humphrey Balanced Solenoid Valve is insensitive to pressure variations. As a result, the switching time remains extremely consistent over the entire pressure range. In addition, these valves are "multi-purpose", meaning you can use them as a 2-weg, 3-weg or 4-weg valve, but also as a selector or diverter valve.

Low leak and no lubrication required

Efficiency is a core value of this series. The valves show excellent low-leak properties and are often tested "bubble tight". This minimises compressed air loss in your system. In addition, the valves are designed for use with both dry and lubricated air, which considerably simplifies maintenance.

The differences: 153/154, 193/194 and 253/254 series

To make the right choice for your application, it is essential to understand the differences in port size and flow capacity. The breakdown below shows the specifications of the three main series:

1. The 153 / 154 series (15 mm)

This is the most compact version, ideal for applications where space is limited.

• Port size: 1/8 PIPE.
• Flow (Cv): 0.25 for the 3-weg (153) and 0.16 for the 4-weg (154).
• Power consumption: Low consumption of 5W (DC) / 5.2W (AC).
• Weight: Only 0.2 lbs (approx. 90 grams).

2. The 193 / 194 series (19 mm)

The mid-range model that offers an excellent balance between size and flow capacity.

• Port size: 1/4 PIPE.
• Flow (Cv): A big step up to 0.65 (3-weg) and 0.47 (4-weg).
• Power consumption: 6W (DC) / 7.7W (AC).
• Weight: 0.4 lbs (approx. 180 grams).

3. The 253 / 254 series (25 mm)

The "high flow" powerhouse for heavier pneumatic cylinders and actuators.

• Port size: 3/8 PIPE.
• Flow (Cv): Maximum capacity of 1.20 (3-weg) and 1.12 (4-weg).
• Power consumption: 8W (DC) / 9.8W (AC).
• Weight: 0.7 to 0.8 lbs (approx. 350 grams).
